now here's my question. i notice rubbing when i turn my wheel all the way and drive. also, the light only comes on after i've made some sort of turn and seems to go away when driving straight. Is it possible that there is not enough offset and the tire is rubbing causing it to turn slower than the rest and therefore throwing an error code because of different tire speed?

 

what was the code??? how long does it take the light to come on when you cleared it??does it only come back on when you drive it?? if so its a wheel speed sensor then you should have a relevant code

 

the only code i got was the p1606. unfortunately i don't have a audi specific diag machine to give me a more specific code.
light does not come on when i first start the car. Only comes on after i have been driving. then the light will come on but it will go away when i get on the highway.

 

ABS module fault

 

so its safe to say that the wheel rubbing issue is not the culprit?

 

clean all the pins to ensure a good connection but you will need vag to reset

 

to clarify.
clean all the pins means make sure all the sensor's are clean? i cant use a generic ODB2 diag to just clear all codes?

 

correct how can you expect a signal if you have been usibg the car off road (dirt build up on the sensors) are we close??

 

i haven't been using the car for offroad by any means. It is strictly road driving. for heaven's sake - i just spent 1600 on 18" rims. the last thing i want to do is put a scratch on them. They're quite shiny

 

i dont see why not a generic obd2 reader wont do the job.
trust me... i'm a licence mechanic i dont whopp out the big guns untill i have to. i use a hand held mac tools scaner for quick diagnostics and servicing unless i go in for a closer look. the VAG toold dont have anyhting special besides the "factory shortcuts" to a certain modes for relearn and adaptations which can be donr if your knowlegeable enough with the proper tool it can be done.

off the top of my head i would grab a multimemeter and would make sure the the ABS module has a good ground, clean power and if acess to a scope would be nice to check the integrity of sensors and wiring by backprobing at the ABS control unit. if everything ok then move on to replacing the ABS control module.

heh...
my car before i bought it went to 7 ot 8 shops and 40% said that the car needs a transmission and the other 60% said that it was in dire need of a tune up...
the problem ???
2 bad fuel injectors
figgure that one out how the techs came up with the first 2 diagnostics !!!
