Sanky Posted January 16, 2022 Report Share Posted January 16, 2022 (edited) So went for a drive this morning, and noticed my interior are not going with the engine running. Or timing out when you close the door. They do go off if I lock the car. Looking for some pointers, before I go studying the circuit diagrams. Also, can’t recall if they are meant to fade out once the car is locked. As they are just going off now.

½cwt Posted January 16, 2022 Report Share Posted January 16, 2022 Moisture (or at least corrosion resulting from) in the alarm control unit under the passenger seat was found to be the source of my interior lights problem, but this was them not working at all....

edc Posted January 16, 2022 Report Share Posted January 16, 2022 Does the door microswitch trigger the turn off light sequence? Quote Link to comment Share on other sites More sharing options...

Not sure, as there are 2 connections for the interior lights that come from the alarm module. But they also power other stuff that are working. Will try and disconnect the door lock modules to see if it makes any difference. Or I could just use it as ambient lighting 🤣 Quote Link to comment Share on other sites More sharing options...

No. I do not think so. If you unplug one of the modules, you will introduce other alarm/central locking issues. As per FB, have you got Durametric or access to it or PIWIS? If so, it will probably come back with a lock synchronisation fault but only PIWIS will be able to tell you which side is your culprit. 1 Quote Link to comment Share on other sites More sharing options...

Might have to give it in for diagnostic at specialist. Edited January 16, 2022 by Sanky Quote Link to comment Share on other sites More sharing options...
½cwt Posted January 16, 2022 Report Share Posted January 16, 2022 Hope Paul's info gets it sorted. On my 2000 car the interior lights and sun visor vanity lights all go back to node B7 in the main fuse box. The only circuit from this is back to a single connection in the alarm module. The luggage space lights are on a separate circuit however. Took some time to prove but with wiring diagrams for Richard Hamilton it was sorted eventually. May ahve been some changes for face lift with CANBUS introduction etc. However this was for the lights always off, not experienced a door latch issue first hand (yet ?!?). 1 Quote Link to comment Share on other sites More sharing options...

So left the car unlocked and the front open with a trickle charger. All lights went out after a couple of hours. So the problem is with the door lock module. I’m thinking the drivers side, as it’s the one that’s used most and the fact the passenger door hasn’t been opened in awhile. So next question, are the VW door lock modules any good?

I replaced mine with a Golf Mk5 lock and it’s been fine in the 2-3 years since. I did need to trim off a bit of plastic before fitting as otherwise it would have jammed. Easy enough to see when you compare with original. I seem to remember that I had to check whether 7 or 8 pins were present in the current lock to ensure I ordered the right one, maybe a MkIV lock for the 7 pin?

iborguk Posted January 17, 2022 Report Share Posted January 17, 2022 Also invest in some door card clips ahead of the swap-out, they can break as soon as you look at them. 1 Quote Link to comment Share on other sites More sharing options...

You’re right, It’s changed since I did mine when the Boxster ones were all £80-90. Quote Link to comment Share on other sites More sharing options...

Yeah there are plenty cheap ones in eBay, just not sure which is the correct one. As some have 7, 8 and 9 pins. Might just pick one up from OPC, as I don’t fancy removing then finding out it’s the wrong one. Unless someone can point me in the right direction for one 2003 Boxster Quote Link to comment Share on other sites More sharing options...
Sanky Posted January 17, 2022 Author Report Share Posted January 17, 2022 Does this part look right, not ordered from AUTODOC before. So a bit feedback would be appreciated as well. https://m.autodoc.co.uk/metzger/13819128 Quote Link to comment Share on other sites More sharing options...
½cwt Posted January 17, 2022 Report Share Posted January 17, 2022 AUTODOC is OK as long as you are happy with 8-10 days delivery. Their cross referencing of OE and actual manufactures part numbers (e.g. Porsche's part number and Bosch's part number for the same thing) is quite handy too. Prices are good and they have been reliable on the 4 or 5 purchases I have made from them over the last 2 years. They are on Topcashback too so you can get a bit more discount that way. 1 Quote Link to comment Share on other sites More sharing options...

Not sure what tool they used, but the door lock modules are responding as they should with the diagnostic software. Think I might have to manually check the wiring in the doors one at a time. But going to try disconnecting the battery first and see if it makes any difference. Edited January 18, 2022 by Sanky Quote Link to comment Share on other sites More sharing options...
Sanky Posted January 18, 2022 Author Report Share Posted January 18, 2022 Can someone please tell me if the interior lights stay on if the car is locked and the front trunk is open? Quote Link to comment Share on other sites More sharing options...
½cwt Posted January 18, 2022 Report Share Posted January 18, 2022 Luggage space and interior lights are on separate circuits. You show as 2003 on My Ride is it an '03 model year or and '02MY on an '03 registration? I have the '00 and '02 Alarm wiring loom circuit diagrams as a PDF if it would help, otherwise calling @Richard Hamilton. Quote Link to comment Share on other sites More sharing options...

Just need some pointers in the normal behaviour so I know where to look next. Could do with a donor car LOL Quote Link to comment Share on other sites More sharing options...

If it were feasible I'd suggest meeting up with him but he's in Maidenhead... Edited January 18, 2022 by ½cwt Quote Link to comment Share on other sites More sharing options...
Richard Hamilton Posted January 18, 2022 Report Share Posted January 18, 2022 I recall having a problem with a 986 a few years ago with very similar symptoms. The alarm module had slipped into transit mode, and needed the vehicle handover routine to wake it up. 1 Quote Link to comment Share on other sites More sharing options...
