Central locking not working

All UK A2s, irrespective of spec', have remote central locking. A majority of UK A2s were sold with climate control, and without rear electric windows. Consequently, there is a chance that a CCCU sourced from car A will be compatible with car B without having to make any coding changes. But nevertheless, it's being left to chance. Whoever fitted the replacement CCCU to @Darpod14's A2 either believed the 'plug-n-play myth' or didn't have the necessary knowledge and/or equipment to do the job properly.
Just because the doors lock and unlock properly doesn't mean everything is hunky-dory. @Darpod14's doors were all locking and unlocking just fine, but the CCCU wasn't registering their open/closed status due to incorrect coding. As another example, the owner of a car with heated mirrors fitted could find that the heated mirrors no longer work after a CCCU swap unless the replacement CCCU is correctly matched to the car.
The coding of CCCUs in the UK is drastically different to those in Ireland, despite both vehicles being right-hand-drive. 15 years after production ceased, many A2s have crossed the Irish Sea in both directions. There are a couple of Irish A2s in my area (I live on the west coast of England, near ferry ports) and there are plenty of A2OC members in Ireland who have imported UK-spec A2s. All manner of issues would arise in both specifications of car if a replacement CCCU were to be fitted without properly matching it to its new host car.
I could be in danger of labouring a point here, but we must get away from this idea that CCCUs are plug-n-play.


If a CCCU replacement is needed, there's isn't even the need to visit me. The whole process can be done remotely. Please see this thread...

Kind regards to all,

Thanks for the clarification Tom. I guess that you could say that I was just lucky with my swaps. I have never had to change the basic coding to set up the four door/ two door electrics setting. But I now know where that is.
Sincere thanks

Interesting thread on coding CCCU's on this very forum Here

Almost no traffic on the thread so not sure how many people have tried diddling around in this area, although now I've seen it I don't suppose I'll be able to resist getting in there.

I quite fancy the option to turn on the coffee-maker after driving 75 miles for instance (although I might have dreamed about that one).
Cheers,

that is a useful post. When I posted my list of the basic settings the other day, I was sure that it must have already been posted.

the second part about the 2/4 door electrics is very useful too.
Cheers

With luck like that I should pick 6 numbers for the lottery, although many A2s just have only electric fronts as you said.
I will now make double sure next time.
Cheers

Thank you everyone for the advice it's definitely given me some food for thought, I'm glad I didn't just get stuck in without asking.
Much appreciated. ?
