neilmcf72 N Morning - I've been suffering with battery drain issues, intermittently for a while now. I borrowed a friends Carista diagnosis tool and my car has thrown 8 Errors out, I've done a lot of googling but the info is sketchy so wondered if anyone could shed light on what they are and what parts I need to fix. Also would be interested to know if these could cause battery drain issues / or are caused by it. Car is a RHD '03 e65 730d. Codes are... A097 A0A7 A0B7 A0C7 9CBC 9C64 9C76 9C56 Any help is appreciated #1 · Nov 14, 2018 Morning - I've been suffering with battery drain issues, intermittently for a while now.

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? 0 Reply #4 · Nov 14, 2018 9C64 - Automatic recirculated-air control (AUC) sensor code 9C56 - check here 9CBC - adaptive headlight problem, mostly a bad light control module. #5 · Nov 21, 2018 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 #6 · Nov 26, 2018 Bump: any help on the above part list would be much appreciated. Thanks. Insert Quotes Post Reply
