Have you shown us your fuse box for a reason? There's a known Mk2 instrument cluster fault, but you need to give us a fighting chance to diagnose...

I'd suggest that either the plug is loose/damp/corroded or one of the relays is stuck. The relays aren't easily replaceable so I'd probably swap the whole GEM for a good used one myself. It's definitely worth checking the plugs first, unplug and check that all pins are clean and dry. 2 Quote Link to comment Share on other sites More sharing options...

The "GEM" module is the brain of your alarm/central locking/double locking/window closing. That central red LED on the cluster is the 'alarm' LED... 1 Quote Link to comment Share on other sites More sharing options...
FociDoci Posted January 4, 2021 Author Share Posted January 4, 2021 Thanks. A bit of backgorund because the original thread seems to have disappeared - I had the cluster repaired because all the lights came on and then car wouldnt start. Car still doesnt start after repair and when scanned had following network codes:- U0131 Lost Communication with Power Steering Control Module (PSCM) . U0155 Lost Communication with Instrument Panel Control (IPC) U0140 Lost Communication With Body Control Module U0121 Lost Communication with ABS Module U0001 & U0073 are rather generic, and only confirm there is some sort of CAN bus problem. Now this after cleaning connectors. No electrics, c/l the lot and still wont start. Because the car is immobile I am at the point of scrapping if they are not easy DIY repairs as I am at my wits end now! Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted January 4, 2021 Share Posted January 4, 2021 Do you trust the place that repaired the cluster? Any warranty on it? Quote Link to comment Share on other sites More sharing options...

TomsFocus Posted January 4, 2021 Share Posted January 4, 2021 I'm not convinced tbh... Lots of CAN faults on a Mk2 generally is caused by the cluster. Presumably there was something wrong with it otherwise you wouldn't have been charged for repair? Alternatives would be a PCM fault or loom damage, neither or which would be cheap or easy to sort. 1 Quote Link to comment Share on other sites More sharing options...
FociDoci Posted January 4, 2021 Author Share Posted January 4, 2021 I took out the fuse box and there does appear to be some corrosion on some of the pins. https://ibb.co/tLYwvLB Could this be it and would you think if I clean it with some wd40 and micro drivers it may fix the issue?

Don't use WD-40, it's NOT designed for cleaning electrical contacts/connectors. Use a proper electrical contact cleaner such as this. 2 Quote Link to comment Share on other sites More sharing options...

Where exactly is the GEM module within the fuse box or is it just another name for the actual fuse box itself? Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted January 4, 2021 Share Posted January 4, 2021 The GEM happens to have fuses in it, it's a lot more than just a simple fuse box inside. Quote Link to comment Share on other sites More sharing options...

It's full of electronics inside, it's not just a simple fusebox like older cars had. Your picture doesn't work for me but if the pins are corroded that'll be at least part of the problem. The GEM may also be wet inside if the corrosion is that bad. 1 Quote Link to comment Share on other sites More sharing options...

If thats not it then off to the scrappy she will go! 2 Quote Link to comment Share on other sites More sharing options...
FociDoci Posted January 5, 2021 Author Share Posted January 5, 2021 Gone back in today and its just the same. Flashing is completely different again. Still no central locking, lights etc. Loose connection in the wiring somewhere maybe. Anyway, it pains me to do it but she will be scrapped this week, that is if theyre still open with lockdown 3.0 up on us? Won't be needing a car anyway I guess. Sad times indeed! 1 Quote Link to comment Share on other sites More sharing options...
