Big big problem!!!

I was driving in town one day and in one minute all the lights came on...i have no ABS no ESP...the brake light i know what it is(hand brake i tooked out the motor on the right hand side loooong time ago), airbag- it's the right passenger side igniter something...i care about abs esp and the headlight thing ohhh the range for the fuel sometimes is 0 and the speedometer is not working but only sometimes...this happens since the abs and esp and headlight range thing came on...please give me any ideas cuz i'm speechless

A bit of a WAG without a scan,
 
but a likely guess is the combo clock spring/angle sensor that sits behind the steering wheel assembly. The clock spring interconnects the horn, airbag and steering wheel switches, while the angle sensor reads the steering wheel position for stuff like ESP and adaptive lighting. Hence why you are seeing that range control warning, plus some of the other symptoms you describe that overlap other elements of that component.

It failed once on my W12 during warranty, and apparently again recently for the clock spring part that connects the airbag electrically. You have to remove the airbag, steering wheel and the steering column trim covers to get at it. Part costs several hundred $ and is essentially dealer only.

well let me see if i got it...all my problems (NO ABS = NO ESP = HEADLIGHT RANGE CONTROL DEFECTIVE) is from the clock spring/angle sensor? the red brake light is from the e-brake the airbag from a igniter like i mentioned...

ohhh i changed the front brake pads recently...maybe it gives you any ideas

Not sure about ABS but...
 
IIRC it may come on as a warning light when ESP light comes on. Yes, the other two warnings can come directly from the angle sensor issue.

I would get it scanned to confirm given the cost of the part.

Brake pads not relevant except for a brake pad wear warning light type issue. That would not play into any of these warnings, unless you physically damaged an ABS wheel sensor. But that still would not explain the headlight range control one, except maybe if you also managed to mess up one of the suspension height sensors...in which case it would likely show suspension height problems too.

Net, the angle sensor/clockspring remains my best guess. Scan it to get more validation, or some alternate issue.

Ok i will scan it...i am starting to not like this car...every day something new...first parking brake motor then suspension and now everything is on...i know its december and christmas is coming but i don't want lights in my car i rather have them on a christmas tree...to much electronic...:((

This are 3 codes that came out from the scan...i have no idea what they are...please help!!!

MP4.2+6.0 12-21-2013 12:18 PM

All those codes are the same, but generic...
 
That looks like a generic code reader. You need access to VCDS/VAG-COM to get the manufacturer (Audi/VW) specific info and a better explanation. The generic readers typically don't work across all the control modules of the car either, so I don't think there is adequate info. from the scan.

Ohhh ok...ill try to find a VCDS...man its like a nightmare...i need a old school car or a vacation away from this one...thank you very much for you time.

mario4.2V8 12-28-2013 01:30 PM

yes its the module...i have to buy a new one(960$ dealer price) or to get it rebuilt but i don't know where to do it. I don't want to send it to some dud with a soldering gun and beer next to him. Can someone give any advice if its closer to Chicago Illinois it wold be amazing.
