Hello, in my 01 TT the tech works when ever I hit a pothole and living in NYC potholes are something you cant avoid. So if its a big one. The tech begins to works with out the problem. If I hit another big pothole the tech gauge moves in an irregular way basically its like sticking and then it drops to zero. From the another car i have a data logger so when I plug it in I get full rpm reading. Now I know that gauge issue is a common problem with the TT's but maybe someone also had a similar problem. and If the question arises the fuel gauge reading reads all the way up all the time unless ive driven about 200+ miles the needle drops to 3/4 full. In the FAQ's i read that its the sending unit problem I cleaned the brush but it seems that it had no effect. I didn't remove the sending unit out of the tank. If anyone have any advice about both of the problems any help would be appreciated.

on top of the battery. They can get corroded and cause electrical gremlins...

Also replace your temp sensor with a green one...

I will check the fuses thanks for you reply, but what do you mean replace the temp sensor with the green one ? whats the green one and where do I get it.

and the temp sensor has been a problem for many, and cured MANY different electrical gremlins....

Search the forum archives, plenty of info on it....general pricing, location and how to fix is well documented.

Thanks I just searched and found the part number and location of it. Going to go to a dealer and pick it up. Its about 10$ price difference from other prices Ive seen, thanks I hope that will fix the problems.

Well I replaced the temp sensor and the problem is still there. So is it possible that its the gauge cluster. And is there a way to find out if it is?
