i think we should bet, do the $5 diy senosor and see what happens or let him replace the t-stat and all and see what happens. i gots a $50 on the sensor. coincidence maybe but i think it will work.

RE: Coolant temperature fluctuates
UPDATE on this issue...SAudi, I think you should've taken the bet.
I took my car to the dealership for some under-warrenty repair, and I mentioned my temperature fluctuations. I described the problem, told him I replaced the sensor, and then told him about the whole "ECT doesn't control the gauge temperature" theory.
His reply: "We checked the coolant system, and its working fine. Normal temperature and no codes. And the ECThas two leads coming off of it, andis connected to both theengine control moduleAND the temperature gauge in the dash. I'd recommend you stop listening to those guys on the car forums, most of them don't know what they're talking about."
[:@] I hate having a dealership service tech making me look dumb.
Anyways, this guy seems to disagree with AudiTech79...and it would be in his best interests to find a problem with my car, so he could charge me for it. PLUS the problem has gone away since I replaced the ECT. So based on those two factors, I'm gonna have to disagree with you on this one, AudiTech.
Just adding this in case someone is searching the archives in the future...and if you have conclusive proof to rebutt, by all means please share it.
Nothing but love...

Im gonna call Hienz again and see if its wired differently from year to yearand engines.
It might be different from model to model too so i'll get to the bottom of this retarded debate.

Yeah, I'm just mystified at this point. It wouldn't surprise me at all to find out that the dealership was full for crap, so by all means, let us know if you find out.
