Title: Central Locking VCDS-Lite codes
Post by: itsahabit on July 10, 2018, 12:14:58 PM
I have a central locking issue where the driver's door, fuel flap and tailgate all work without issue but the passenger and rear doors do not work.
I've checked under the door/tailgate gaiters and there are no obvious breaks in the wiring.
 
VCDS shows the following errors:
01145 -  Central Locking Motors; Unlock Rear Doors        29-10 -  Short to Ground - Intermittent
01179 - Shareware Version. To Decode all DTCs        35-10 - Please Register/Activate - Intermittent
01146 - Shareware Version. To Decode all DTCs        29-10 - Please Register/Activate - Intermittent

As I can't afford to register VCDS-Lite atm I looked up the other codes on Ross-Tech. The second code is key programming (My spare refuses to program so that figures) but the third code (01146) isn't listed.
If anyone knows what it is it would be really helpful.

I'm considering taking off the door cards and checking the resistance of the wires to see if a cable is at fault below the insulation next. Any ideas on what else to do next appreciated.

Hi.

I had some wiring issues with the doors. I found that the breaks in the wires were very obvious in the bellows between the door and body through constant movement. I soldered in a new bit and sealed them with heatshrink. My drivers door has started playing up so I will be doing the same on that one sooner or later.

Cheers

Sorry, Just read the bit where you already checked for broken wires.... :-[

I think the 1146 code is just generated by it not being a registered copy of vcds and can be ignored.

Check fuse 27 on the fuseboard - see this post for more info on why I've said that

Fuse 27 checked and all appears OK.
Worked out that the VCDS error code 01146 is the front door central locking motor.

Looks like all the door cards off next. Seems odd that three motors might fail at once so I'm still thinking there's some invisible damage somewhere.

More likely one of them has failed in such a way it knocks the others out.

Does it do anything if you try to lock from the passenger side door?

It's a later model with no lock barrel for the passenger door, but operating the door lock internally does nothing but lock the passenger door itself.
I've decided that the next step will be to take off the passenger door card and see if the there's a voltage at the door lock motor when the locks are operated. That might quickly rule out a lot of chasing of wiring seeing as all the other door electrics (mirrors, windows, etc). are fully functional.
It could be as obvious as the lock motors at fault!

Have you had any looms disconnected at A or B post?

When I repaired some wiring on mine I still had issues and was convinced a motor had gone down,turned out inside the socket on A and B post the electrical connection is made up of several contact blocks within the socket. On refitting one of them had pushed back,had to gain access from rear to push back in and hold in place while reconnecting the plug.

Even if you haven't had the connector apart, someone else previously might have been in there, so check as Johnny says above. I'd suspect its one of the front doors at fault, usually the rear doors if they play up just don't lock or unlock, they don't usually affect the other doors. It could be a lock motor, unplugging the motors should give you an idea which one if so (if you unplug the drivers motor and try the passenger one if that then works I'd suspect the drivers door to be at fault, either wiring or the motor itself)

I think if i remember rightly you have only recently got the car, and it came with the faults listed?

Yesterday I disconnected the front passenger door loom at the A pillar. To the best of my knowledge they've never been disconnected before. The car is single owner (known well to me) and the central locking issues started recently and haven't been investigated.
I found nothing obviously amiss but I did clean the connectors with switch cleaner before reconnecting (not as easy as it sounds).

Amazingly after reconnecting the loom the passenger door now works! Maybe it was just as simple as a bad connection.


So now I just have the back doors failing to lock/unlock on the central locking. As soon as I get time I'll try the same trick on them to see if it helps again.
