2007 A8 3.0 TDI - VCDS questions from a beginner
Bought my first A8 at the weekend, and had my first VCDS scan on Tuesday night (thanks go to tc4332 - Ray you are a gent and I owe you one).
After we cleared the old codes out, only had 2 persistent faults showing up: 1. Voice control was in CP (which seems a bit weird but Im not bothered cos I wont be using it) 2. Engine Mount solenoid valve short - should I be worried about this or can I safely ignore it? I'm hoping to borrow a VCDS from a workmate, and would like to know if the following options can be coded on an A8 D3 2007:
Ive done loads of reading in other forums but cant seem to find anything specifically relating to a 2007 A8, so any advice on any of the above would be much appreciated. Thanks Adam

Mirrors can't fold in by locking the car without adding a module being wired in. A few owners have done it but it's a shame this can't just be coded in.
More bass from Bose - just turn up the bass a bit? Lol Needle sweep is standard on facelift S8s and W12s but can't see a reason why it couldn't be coded in to other models by going to module 17 (instruments) then coding (07) and follow the simple instructions.

As Ollie has said mirrors need electrickery to make them do that, its not a feature that can be coded.
I know nothing about the bose, but you can test the audio system with vcds Needle sweep is a function of the cluster firmware, later years and can not be coded or adapted

Hi Adam This seems to come up on many D3's, its a fault in one of the active engine mounts and requires the mount in question to be replaced. Most people tend to wait until they are doing something that requires the engine lifting a tad or front end off etc (like cam belts etc) and do it then. You can continue to ignore it if it doesnt worry you and you can live with the fault code

I changed one side on mine and a year later the other side went. Can't say I noticed any difference before or after the change

Cheers guys for the advice. Don't think I'll be worrying too much about the engine mount then!

Adam,
I have something similiar that has not deteriorated during our ownership. 1 Fault Found: 18278 - Transmission Mount Valve 1 (N262) P1870 - 001 - Open Circuit Freeze Frame: RPM: 777 /min Torque: 46.8 Nm Speed: 0.0 km/h Duty Cycle: 1.0 % Voltage: 14.52 V Bin. Bits: 00101100 Torque: 202.8 Nm Temperature: 54.9°C Readiness: 0 0 0 0 0 I think that it is the sensor that goes faulty rather than the actual mount.

There is no sensor in the mount, only valve. At idle valve opens to allow liquid in the mount move more freely and absorb vibration. Under load valve closes to reduce engine movement. I think by default valve is closed so if it has failed you will have more vibration at idle but it's hard to notice. Sometimes it's just corrosion in the plug.

Ainar, thank you - what you describe is exactly what is happening with my car. I think I can cope with the slight vibration at idle, next time I have any work done on the engine Ill ask for a price to replace mount.
Thanks again
