A097,A0A7,A0B7,A0C7 PGS (Passive Go System),so door handle failure may cause battery drain.
9C64,9C56 Climate control
9C76 Aux water pump
9CBC: LM: Communication with SMC, left, disrupted

 

Thank you very much, really helpful.

So door handles is where I will start (I assume that the 4 codes relate to each of the handles).

Any clues specifically on the climate control? - I'm trying to build a parts list so I can get them all sorted and replaced.

Aux water pump seems easy enough.

9CBC - Still a bit puzzled on this, any idea what it practically means?

 

9C64 - Automatic recirculated-air control (AUC) sensor code
9C56 - check here

9CBC - adaptive headlight problem, mostly a bad light control module.

 

Ok - thanks so far.

So I'm going to try over the next few months DIY this - and I've brought in another couple of issues from another thread. Thoughts / help / opinions very welcome.

Battery Drain & 4 codes

I'm now convinced this is down to the 4 error codes that fired from door handles (A097,A0A7,A0B7,A0C7) - I removed the fuses for the right hand side of the car and haven't had any battery drain since. What are the chances of it being both front driver and rear driver? Slim I imagine so I'm going to try replace the drivers front handle.

Is the correct part number 51217191900?
Do I need any coding or are these plug and play?

Key Fob

I know the obvious answer to this - I'm getting a battery low warning, but it's not been long replaced. I'll try again with another new battery and switch between the fobs, but is this likely to be linked to the door handle issues or is it something else?

9C76 Aux water pump

Seems straight forward enough, is the correct part number 64116922699?

9C56

Was sketchy on this one but would this be the part number to cause the issue 64116910342

9C64 - Automatic recirculated-air control (AUC) sensor

Again is this the correct part 64116933052?

9CBC: LM: Communication with SMC, left, disrupted

Still no real clue on this on, despite the help

So does the above all sound correct before I start spending money on parts?

Thank you very much

 

Bump: any help on the above part list would be much appreciated. Thanks.
