Hi All, I've had a 07 Plate VW Sharan for roughly 3 months now...and had nothing but electrical nightmares with it. (Two replacement door wiring looms and 2 door motors and another latch to sort the central locking out). Interior lighting not working..etc etc. I've sorted all this out as a reluctant amateur but now I am on my last (I think) electrical issue. My drivers side wing mirror indicator is not working. Front/back indicators are fine and passenger wing mirror ok also. I took the wing mirror apart and put a multimeter on the pair of wires and got no voltage with the indictators on so suggesting a wiring fault. Just on the off chance, does anyone know if the wing mirror indicators are protected by a separate fuse for each side?? If so, it might just be blown fuse. If not then I've obviously got a wiring problem in the door loom again (which I would be disappointed about as I replaced the drivers door loom on my central locking problems). I did go up the breakers today and walked out with a replacement indicator lamp from a Mk5 Golf in my pocket and tried it....so I don't think its the lamp either....but the lack of voltage had already proved that. Any help would be great on the wiring/fuse position of this.

Might be a daft question, but did the indicator work before you changed the loom? or immediately after changing it and now its stopped working?

Reason I'm asking is a mk2 Galaxy doesn't have those indicators (at least mine doesn't) as they are on the wing instead. If you have a loom from a Galaxy rather than a Sharan now fitted you might find the loom is missing those connections. Its also possible for bits of the connector to come apart, its worth double checking its all pushed together correctly if you can (they frequently fall out of the door pillar, I think you will find some bits of the connector will come apart from the rest as well so worth having a good look there).

Of course as you've already discovered the wiring on the doors isn't great, it may just be more broken wires. Not aware of a separate fuse, but even with broken wires with exposed bits they rarely blow (even though you'd expect them to).

Good point....it was working yes, I wondered if all the times I've had the looms in and out I may have broken the wiring. The loom I got was from a similar registration Seat Alhambra. It had the same item code number on a piece of paper attached to the loom but the new loom does have a connection to an interior door card courtesy light that my low spec Sharan does not have (it only has a blank glass in the door). I have a tone set so was going to buzz the wiring out in a bit....so door card off again. That will be a real pain if the loom is not compatible (though it only cost a tenner). If I'm honest, I'm not that impressed with the electrical wiring on these cars. Many years ago I had a Peugeot 405 which I thought was the pits in terms of its electrics (my heater motor coming on full blast every time I turned left being the funniest) but compared to this VW it was like a shining beacon of light. I was at the breakers yesterday and the wing mirrors on the Alhambra were both removed....so don't know if it had those side indicators.

OK, checked my loom and you were right, the Alhambra cannot have had wing mirror indicators as the plug has the wiring in a different place....mainly my black/white wire from the indicator lamp isn't connected through on my replacement loom. I can sort of get over it by cutting wires, crimping new wires on re-routing them to make a circuit but suspect it'll be a bit messy behind the door card and also at the plug end.  Might be best to just get on ebay and find the correct loom from a Sharan if I can. I have approx. 6 weeks before my MOT is due to fix it and resource the right part. VW Sharan electrics.....the gift that just keeps on giving. :(

Can you remove the indicator wiring from old plug and feed that in to replacement loom?

You should be able to remove old ones with a small screwdriver to release the tab and pull it out? Failing that cut the plug up and then push the terminals in to the new loom.

The door wiring is awful - Its partly down to design faults, but you are looking at a 11 year old car which doesn't help. I'd give what Jonnyroper has suggested a try if you have the old loom still. I think (though not sure) that the indicators in the wing mirrors happened around about the time Ford parted ways on the project, so it may be that your loom is off an older MK2 (pre 2007).

Hi All, sorry for late reply. After approx 2 months of occasional attempts at sorting out my electrical problems I have finally today sorted it all out.  I managed to obtain a proper Sharan drivers door wiring loom from a breakers about 30miles away. I decided I did not want to use the Alhambra loom I had as it was such good condition I did not want to cut it up. But, replacement loom, a complete set of original car mats and a good pair of windscreen wipers (mine were a bit smeary) all for 20.....couldn't go wrong. So today I have got it all in and we are in business. Interestingly, when I tested the voltage at the plug point where the wing mirror indicator bulb plugs in with a digital multimeter and switched the indicator on I found my meter was alternating O.L(overload) and 0v (I was expecting a 12v reading and 0v as it flashed). I took the other wing mirror apart and got the same reading. Put the indicator lamp back on and wiggled it and it started working. I always thought an O.L reading on my meter was indicative of a short circuit. Bottom line is, though, everything electrical on my car that should work now does....so at last I am happy. All that's left now is to see to my handbrake cable, which is not binding at all on one side, so suspect I need a new one.....but that might be a garage job, as I live on a hill slope and anything that involves going under my car generally gets sent to a garage as I like my chest and mobility the way it is !!! Thanks all for the help and advice I have been given.

It might be worth checking that the brake isn't stuck on one side (mine did that after it was sat for a couple of weeks without being used). Moving it about and some wd40 or similar on it was enough to sort mine out and its been fine since. It relies on the spring pushing it back to pull the cable back down, and the springs could do with being a bit more springy from what I found!

Good news on the loom, on the overload setting sounds like you had the meter set to the wrong range to me, what does it show if you put it across the battery terminals?
