I was wondering if anyone could help me find the location of the coolant temp sensor on an A6 4.2. also, if anyone has a detailed layout of the engine bay( different sensors).
I have 79K miles on it and is it about time to get the timing belt replaced or i still have some life left to it. what else could be done at this point(79K miles)
Is there any place in the chicago area for Audis where they do GOOD service? let me know.
thanx guys, appreciate it.

 

Temp sensor is on the backside of the engine, I believe you have to take the air intake off to get to it.Also there is something about a black or green one?
Get that timming belt job done!waterpump, thermostat, serpintine belt, Idlers, tensioners. BENG

 

thanx man...i'll look for it.

 

is it the same place for the 2.7 bc my temp gauge is acting up randomly now and then ... seems to be everytime i go through the car wash it starts saying "C" when the car has been running for a while and was just in the middle

if u have a black one replace it with the green one

i dont even know what the thing looks like

 

I think my 2.8 was in about the same place, mayby they all are. They are about the size of your thumb and are simply locked in by a C type plastic clip. BENG

 

picture??

 

Just by the part, and look for the same part on your car-and replace! BENG

 

yea i was thinking about doing that but i didnt wanna have to take that damn airbox off haha that corner clip in teh back is a pain lol

 

Actually I just looked at my 4.2 and you can see it by taking the engine cover off. BENG

 

hey Beng
my car doesn't respond right away when i try to accelerate.do u know what could be reason.its like when u press the accelerator, it takes about a sec or two to accelerate seems like there's a lag.
thanx man
