I downloaded the manual for my B5 from this site : Service Manual PDF Audi A4 B5 1994 2001 pdf download
and I'm very satisfied about it! Very easy to use and also you will get it instant.

one of two things...cheapest is to change your transmission fluid and filter first. or your pick up modulator is going bad.

you probably have a bad wheel sensor

Water Thermometer by cooling system is called Engine Coolant Temperature (ECT) sensor, and is placed in the right back side of the cylinder head on 2000 Audi A4 - B5 1.9 TDI. See picture below:



Please do rate my response. Thanks!

Hi, the sensor on the engine (right at the rear end of the cylinder head) has two separate outputs. One drives the temperature gauge and the other provides data for the engine control unit. The output for the engine control unit is almost certainly faulty and the sensor will need to be replaced. It isn't an expensive item and's not time consuming to replace (1/2 hr) - so you could ask Audi to do it for you when they replace the ignition coils.
Hope that helps Matt..
