2002 vw jetta tdi - problem with rpm gauge?

I've had this car for over 3 years; had 89000 miles in 2005 when i bought it & now just passed 202000 miles! automatic, few problems, mostly highway miles, very well maintained...

noticed today when driving home on the interstate (usually about 75-80mph), that the rpm gauge which is about 2800 - 3000 rpm's at those speeds, was moving around a lot even when i was on flat ground & maintaining same speed... it was registering higher rpm's than normal & the needle seemed to fluctuate more than normal; didn't seem to be the tranny stuck in 3rd or anything??

wondering if it's a gauge problem, a sensor problem, tranny problem, turbo problem or something else???


thanx, kenn

    2000 TDI, when driving down the rode, maintaing same RPM, fluctuates back and forth around 300 to 400 RPM. Example would be i maintain 2000 rpm, it will fluctuate between 2000 to 2400. The engine responds with the RPM flux. DOes not do it at idle, It idles around 800.

Hi, Did you notice the motor actually reving higher when the tachometer was reading a higher rpm.. If it was it could be your transmission slipping.. Set your cruise control and listen to your motor while the tachometer starts moving erratically.. Good Luck

Should a 2002 jetta tdi- automatic at 87,000 miles


That specific transmission is known for failure. Sometimes it's premature failure (in your case) and sometimes they have 150k miles, but that specific automatic transmission will always fail.
There are plenty of stories online about premature failure of the 01M VW transmission...
