VW SHARAN FRONT SEAT FORE AND AFT ADJUSTER SEIZED
« on: February 25, 2017, 02:12:39 PM »
Hello, This is my first post on this forum but i admit to lurking in the past, sorry. I bought my 2005 Sharan 1.9 TDI 130 brand new and have now done 154,000 miles of relatively trouble free motoring; i bought it principally to haul my family of six up and down from Lincolnshire to Bergerac in France where we lived for a time, this task was performed admirably although the interior has literally fallen to bits in the near 12 years i have owned it. The point of my post is that she finally failed the MOT test this time round on front suspension bushes, top mount bearing play, non opening passenger door handle and seized front seats;  i have fixed all these but the seat problem persists despite all manner of attempts to free them. Neither front seat will adjust fore and aft when the adjuster bar is raised, no amount of lifting and shuffling and swearing will move either seat forward or backward and both are seized in the forward position. They have been like this for at least EIGHT YEARS!! but it has never been an issue before as i am the only driver and the passenger seat has always been fine where it is. It has never been mentioned in previous MOT tests, but the tester this time appeared to be around 8 years old and obviously needed to adjust the seat to reach the pedals hence the fault was found. I can not find anything anywhere which explains the workings of this seat adjustment, it can not be that complex surely but the problem is compounded by the fact i can not get access under the seat rails to remove the seat and hopefully sort the problem out. Is there anyone out there who can guide me in sorting this issue out as currently it is the only thing preventing me from the re test and getting me back on the road. I have managed to remove the two torx bolts on the front of the seat uprights giving limited access to the forward area under the seat by tipping the seat back on its two rear mounting points. I have put stiff wire down the upper and lower tracks but nothing is lodged in there and the release lever mechanisms appear to be working but they are not releasing the locking device to enable me to slide the seats. From memory they both jammed within six months of each other. PLEASE HELP. Regards to all.  John

the bar has some square teeth that locate in toothed tracks to hold in place securely,these are retracted when handle is operated to allow the runners to slide. If it will not budge then you will struggle to access the rear bolts,I would try filling runners with wd40 and letting it soak in for a few days. When you try the seat get someone to hold lever while you put some weight against rear of seat to see if you can free it.

Hello, Thanks for the info, i am a little wiser as to how the mechanism works but not sure how the lever disengages the two rails. I probably shouldn't have used the word 'seized' as the runners are not seized as in rusted together, the seats are locked in position due to the release mechanism not unlocking the sliding rail to allow the seat(s) to move, everything is moving in relation to itself just not far enough to unlock. As i have no idea how this locking system works and as it is hidden below the top rail i can't see what i am dealing with, so i really am peeing in the dark.
Any ideas on how to get the seats unlocked or how to remove them would be a bonus. I can not find a workshop manual that covers my 2005 car, are they available? Thank you. Jon

Does yours have swivelling front seats? If so this will give you a bit more access. I've not had mine apart to inspect it first hand but by the looks of it the 'teeth' of the mechanism engage in recesses on the top part of the runner rail instead of the bottom, which is a little alien to me as the Fords I've worked on had teeth that engaged in the bottom of the rail. Therefore I'm thinking that the sprung loaded release handle 'teeth' that engage in the runner rail are on the opposite side of the pivot point to the handle, so that when you pull the handle up to release the mechanism the 'teeth' are lowered clear of the runner rail recesses allowing the seat to slide.

Thank you for your reply; what you say makes sense as regards the lever action lowering the locking teeth from the upper bar indents but you can not see this action in progress because of the upper rail covering this mystical process! i have just spent another hour this morning on it and still no joy! does anyone have a grenade which should move them?!!!!
I can not see how to progress this other than to dust off the disc cutter which seems a little extreme! am i the only Sharan owner to suffer this problem? Thanks again for your time. I am just having a cup of tea and a lay down before having another go at it. Is there a Haynes manual for my car or does anyone have access to the VW works manual which shows an exploded diagram of the mechanism so that i can see how to attack it??? thank you.
Best.  Jon

Haynes manual (at least the Mk2 Galaxy one) is zero use I'm afraid, all it covers is basic seat removal and installation (I've just looked). Parts diagram is no help either.

Do your seats swivel? As this improves access.

Had mine off several times but never really noticed before, there's a cable that operates the lock on the opposite rail to the handle see pic below maybe the problem is that cable is not attached or broken?
try reaching under the seat crossmember and pull cable at the same time operate the handle.

@Chrispb, do your seats have release handles that actually look like the ones in that overview you posted? Mine aren't like that, the one handle pivots on both sides of the frame as per the parts diagram I linked above.

Hello, My seats do not swivel and my seats on the 2005 model are unlocked by a bar which runs the width of the seat at the front but PLEASE don't waste any more of your precious time on this .... PLEASE READ ON......Good news, i have both front seats sliding back and forth as intended and as the MOT test requires! now the embarrassing bit.... just before i started the disc cutter with the intention of cutting the seat out (yes, really, i had fueled it up!!) i decided to put the metal prodder down the passenger side seat rail as up to this point all my efforts had been concentrated on the drivers seat, i pushed the rod in from front to back and was astonished to see a pencil emerge from the back of the seat track, 'eureka'! i thought, lifted the bar to release the seat but it was still jammed and would not budge, **c*. However i knew this was not right especially as it was a 'My Little Pony' pink pencil!! i found another similar piece of metal rod and poked both down the seat rail 'tunnel' twisting them as i pushed and low and behold out the back came a crushed pencil, a ball point pen and two pen tops, i repeated the exercise down all four tracks and the total haul is three pencils, two pens, three pen tops in various colours, a one Euro coin, a plastic top off a tictac box and a legless Smurf plastic figure!!!!!  Joy as the seats glided back and forth turned to anger and much swearing as it dawned on me that this scenario could not possibly have happened by accident; perhaps the coin but not all the pens, this was definitely perpetrated by two particularly nasty little Gremlins who i calculate would have been around 3 and 4 years of age at the time the seats were first noticed to be stuck. Despite thumb screws and a water boarding session this afternoon neither Gremlin will admit to stuffing the seat tracks with said items. It would seem it was the crushed pencils which were preventing the lever from unlocking the seats. Suffice to say i am pleased this particular saga is over, and i am very grateful to those who took the time to reply to my post for help and look up manuals and scratch their heads on my behalf; kids, who would have them!!!!
 Best regards to you all, and thank you again.
Jon

I am pleased you all saw the funny side of this, i am just starting to have a quiet snigger to myself now but if the Gremlins are about i give them a 'still angry' stare! the seat problem caused me a weeks delay on completing the list of 'FAIL' items on the MOT test notification, it was a real disappointment after 12 years and 154,000 miles of relative reliable motoring as the car has never let me down in that time. HOWEVER in sorting the front suspension bushes out i have now introduced a new problem, the ABS warning light is on and it stays on. I had to disconnect both ABS sensor connection plugs to remove the front suspension legs to change the top mount rubbers and bearings, i had an awful lot of trouble parting the connectors mounted to the inside of the wheel arch and i am wondering if i have damaged the connectors or wiring in some way?? This light has never been on in 154000 miles, what have i done to awaken it?? should i just replace the two sensor leads or is this a more serious problem?? i understand it will not pass its MOT test with this light illuminated so i am still off the road, unfortunately i cant blame my two younger gremlins this time!! i read somewhere that the system needs some miles under the wheels to 're-set' after re fitting these items, is this correct? am i panicking too soon. HELP!!
Just thought, should i be starting a new thread for my latest problem??
Thanks
Jon

I would have a check of the 2 connectors first as they were disturbed during suspension work, did you have shafts out of the hubs at same time? Failing that disconnect battery for 10 minutes and see if that clears the fault,if not get codes read before opting for changing parts.

Thanks JR, i tried disconnecting the battery and starting her up but the ABS warning is still illuminated; i have read much about these readers and diagnostic tools but personally i have little experience of them; do i have to take it to a VW garage for this to be done and what is the likely charge? or would any local well equipped garage have a code reader that would give me a clue? Many thanks for your prompt response, i didn't realize how much i relied on the Sharan until now.

Any decent local garage should be able to plug in for you,alternatively someone on here might have vcds and live local to you?
At least if you get a fault code it points you in right direction rather than not being sure if a sensor or something different.

thanks very much i will have a word with my local 'specialist' ..................and yes, i did have the drive shafts out of the hubs when i removed the suspension legs, i also replaced the lower ball joints and wish bones; i have checked the abs rings and taken out the sensor heads and cleaned everything up, rings look in good condition and no metal particles on the sensor head; plugs look good but i did break both plastic retaining clips on each connector plug in my efforts to remove them but they have gone back in tight and have been pulled up with the aid of a cable tie. what is going on ???????????????

Defo need it plugging in as nothing is obviously wrong with it,could be something else wrong with system and just coincidental happened after suspension work.

Did you have the ignition on at any point whilst the sensors were disconnected? As that could have done it if the ABS control module saw that the front sensors had gone open circuit.

One of the first things i did was to disconnect and remove the battery to give access to the left hand top mount nut (right as you look at it) and i didn't connect up again until everything was back together and she was on her wheels again, so i am more or less certain that i did not switch on with sensors disconnected. what re sets the control module if everything is back as it was assuming i hadn't connected one of the connectors properly?

Once everything was back together and the wheels refitted could the front wheels have rotated independently of each other with the ignition switched on (e.g, if you started the engine with the front wheels still jacked up) ? This could also cause a fault to be logged.

Certainly its possible since starting to investigate the ABS warning light issue that the wheels may well have been turned independently of each other in fact certainly they have as i have rotated the hubs to clean the sensor rings but i am not sure this has been done with the ignition ON. Where would any imbalance or  fault be 'logged' and can this be re - set? if so how? Thanks very much for your help with this, as you may realize i am floundering, turning spanners i can do but electrics / electronics is a dark art as far as i am concerned.

Depending on how the system works (and assuming that the wheels being rotated independently of eachother with the ignition on was the cause), if it (the ABS module) sees no further faults the lamp may go out by itself after a few miles of driving. Otherwise you'll need VCDS to check and clear the codes yourself, or you'll need to take it to a dealer.

Those wires are quite fragile and can quite easily break off at the multiplug.
If it's not obvious which lead is broke vagcom/vcds will pinpoint it for you, once the fault has been repaired you will need to drive the car a short distance (probably less 100 yards) at around 20MPH to reset once the light has gone out stop the car and turn off remove key, now insert key to turn on ignition without starting engine observing the ABS light, it should illuminate briefly the go out, if it does then job done.

ALHAMBRA Front Seats Jammed - Easy Fix
« Reply #33 on: April 27, 2017, 01:10:44 PM »
Hi, Signed up to the forum to say a huge thank you to Sharronducatti for the amusing story about the pens down the seat. My passenger seat has been seized for months now. I had a look and couldn't see anything that would be jamming the runner. Today the driver's seat jammed....... so I was  lucky enough to find Sharoonducatti's thread and went back out with torch to have another look. This time, under the drivers seat, and on the runner nearest to the handbrake, I could see something round (looked like a screw head). Found a wire to push down the runner and could see movement on the object when nudged. Took a long time but eventually I managed to push the offending object back..... it was a pen! Then I tackled the passenger seat. Same thing, found a pen in the runner.

All is now fixed thanks to you guys. And I don't think it was the little ones lol.... both runners affected on mine were next to the handbrake.. I reckon that the pens/ pen lids/ etc slip down onto the runner from the central area.

Saved ££££ on the garage fix. Thanks!

That's a result then! [GJ]

As an FYI, I had the driver's seat out of mine recently to replace the base cushion foam, and took a few pictures (click to view at full res.) of the base and runner mechanism whilst it was in bits- this is the later type seat with the broad release bar which unlocks both seat runners when it is pulled upwards rather than the earlier type which have a release handle on one side only and then a cable which unlocks the second runner:

Seat base as viewed from the underside showing the release bar (the bit sticking out on the left):
5503-0

Close up of the release tabs (arrowed blue) and the teeth in the runner that they engage into:
5505-1

If the runners are jammed and you can't find any obstruction or free them in order to be able to make the seat slide and access the bolts which hold the seat assembly to the chassis, access to the locking tabs can be improved by removing the side trims which run around the side of the seat base cushion, removal of these trims requires any adjuster handles on the seat sides (for height adjustment and seat swivel- if fitted) to be removed, they were simply held on by size 25 torx screws on my model, you just need to pop the covering cap off first. The seat back angle adjuster wheel is held on by 3 plastic tabs, a yank did not release the wheel though so I had to use a fine screwdriver to gently ease the tabs clear, and the trim itself is secured by a single phillips head screw at the front and 2 trim clips on the sides into the seat base. These trim clips do not release easily and the slots in the trim they slide into are opposed to eachother so you cannot undo the screw and slide the trim free of the clips (leaving the clips sat in the seat base) unfortunately.

View of the seat base side with adjuster handles/ wheel and side trim removed (note the 2 yellow trim clips in said trim), showing the improved access which can be gained by removing the trim. If the seat has a height adjuster, ensure the seat is at it's highest as this gives more clearance between the seat cushion base plate and the runners:
5507-2

Excellent information! Same long single bar mechanism as I have. I have seen quite a few people trying to work out how to unjam these seats. I couldn't find anything as clear as your post and photos showing how the mechanism works. Luckily we didn't get that far this morning.... I was on track to start removing the seats when I found the thread about using the wire to push through any debris, had one last go and discovered the pens. Many thanks.

Interesting that this base appears to have provision for the seat to swivel but I can't see any controls for that.  Or is the circular form just a strengthening rib?

The swivel mechanism is controlled by a release lever (the spindle which one of said levers is mounted on is circled blue below) on the side of the seat, not all Mk2's had the swivel option, more basic models didn't (I think), nor models with the factory fitted DVD player with screens in the headrests. The rotary channel which the seat swivels in is arrowed red in the below image (with a corresponding channel visible on the other side of the base), the white part (visible right at the head of the arrow) I'm assuming is one of several nylon bushes which guide the upper seat assembly around in said channel, whilst the circular white nylon bush in the centre of the base is obviously the central pivot point.

So the control for swivelling is on the inner part of the seat, next to the central binnacle?  Explains why I've never been able to find it.

Talking about convenience features, I discovered recently that my wife's focus has the cooled glove box.  It's easy to retrofit to the Mondeo and possibly the Galaxy.  I'll be trying it out soon....

On my Galaxy, it's the lever on the outside facing (i.e, door facing) edge of the seat that releases the seat swivel mechanism. The inside edge (the edge facing the handbrake lever) of the driver's seat has another lever which is the seat height adjuster, this lever is absent on the passenger seat which does not have height adjustment, at least on my model. There is a recess in the trim for the lever to sit in but the hole where the release spindle would pass through is blanked off. The swivel mechanism release handle on the assembled driver's seat is circled blue in the below picture.

R.E fitting the pipework for the glovebox air con/ cooling, IIRC on the earlier models (eg, Focus) it made the pollen filters somewhat more tricky to change, not sure if the design has been changed or the pipework routing altered on more recent models?

Thanks for the info.  I've seen that lever on a few examples but it has never seemed to do anything.  Maybe it was the curse of the pencil.....

If the pollen filter was more tricky to change on the Mondeo, I would need to grow at least one extra hand.  I need to be upside down in the passenger footwell as it is.  "Daddy's pretending to be a beetroot again!"  Presume it's similar for the MkIII (onwards) Galaxy?  Never done it on the Focus, as my wife insists on having a "real man" (TM) from the Ford dealer do it.  I presume it's never been touched.....

When you pull the release lever upwards to release the swivel mechanism it does need a fair old shove to get the seat moving, not only that but the seat back and position of the seat fore and aft on the track runners is critical, otherwise the seat hits either the steering wheel (driver's side only obviously) or the door pillar. Unlike the seat tracks I don't think foreign objects could easily enter the swivel track or latch and jam it up.

Yes you do need to be a contortionist to get up into the passenger footwell to renew the cabin filters on a lot of the newer vehicles, the Mk2 Focus etc. you had to lower/ disconnect/ take the fusebox/ 'body control module' out of the vehicle to replace the filter, and as you say for this reason a lot of technicians on time save bonus never bothered changing 'em, just like the Mk2 Galaxy. Not sure if the newer stuff is the same but if it is then the same applies! The Mk2 Focus with glovebox cooling was made even harder by an air-con pipe which ran close to the filter cover, reducing access and working space further!
