Snag list
Today I decided to create a list of faults my car is currently carrying.
Most if not all are electrical and all are intermittent, no real pattern. Adaptive headlight fault and bulb failure (NS) Driver door handle LEDs Auto boot just unlocks but not open, doesn't even whine/strain DIS blank/black on start up for 2-3 mins Rear windows sometimes will not fully close at one touch Could a weak battery be the cause or is the A8 prone to elec gremlins? An additional question. Should the boot and fuel buttons in the drivers door illuminate? Mine do not. Other than that engine pulls like a train, gearbox is great and MOT due on Friday! Many thanks.

I would say probably yes, I get intermittent low battery charge warnings and the boot only opens automatically when the car is running or has been running for a while. Put it on a CTEK the other day, seemed to solve the issue, 3 days later, same problem, got the battery low charge warning again today. Charged her again and all is now well once more!
Good luck with the MOT |

Does the button on the inside of the boot lid illuminate?

Just go into the battery coding and change the end digit to +1 from where it is and you'll probably find all is well again for a long while

I bought a new bootlid motor not realising the reason my bootlid didn't rise electrically was because of a battery with little charge!

A new battery solved over 50% of the initial electrical gremlins after i bought mine

Only happens when the battery is low on charge. Happens to me often..there is something draining the power somewhere but the Energy management system does a good job at keeping enough charge to start the engine.

Got the Weak Battery message today for the first time. I do not have the ability to code so looks like I'm heading to a main dealer. Thanks all for the input.

Aren't you pretty close to me? I'd be happy to code your new battery for you, if required. I just need my VCDS from my glovebox first.

Yep, thanks for the kind offer. I am in Putney weekdays, SW at the weekends. That would be great if you could, imagine it would save some £££.
