Hi people. I am new to this forum.
I have a problem with my Audi 80, 1.9 TDI from 1992.
When I bought the car the temp. was constantly at 80. One year ago I got problems with the temp. going up to about 95 under heavy load. I contacted my Audi dealer, which changed pump and thermostat, but the problem was still there. They then told me that the water was leaking into the engine, and that this repair would cost 2,500$.
I went to another mechanic who told me that the problem was not with the water leaking into the engine's oil, but he was unable to fix my problem.
Then came winther, and it got a little better, so I didn't worry about it, until this summer, when the problem again got worse.
When I drive up-hill I get temp. around 95, which is too much. Sometimes it reaches 100.
Anyone got any ideas? How high temp. can the car take before I should worry about it?
There are 2 fans in the front. When are these supposed to start working? Yesterday I started the car in the carage, and the temp. got up to 100 degrees, but the fans were not moving. Is this normal?
Overall it seems that the car enjoys beeing between 80 and 95 degrees. If I don't put load on the car, the temp. will fall to 80. When driving up-hill it goes up to 95 - 100.
Any kind of reply is appreciated.
Thanks,
Limbo

It may be simple as a fan switch, also check if thermostat is open when hot, just check if bottom hose is hot.
It also might be simple as fuse, chech them first.
then if okey just turn the key on, dont start the car just light up the panel, disconnect fan switch and shorten it so that it would start the fan. if works its good, doesn't bad. check the ground and positive wires under and on driver side in front.

Check the obvious first. Check the radiator so that you can see through the fins and that the fins are not corroded and/or disintegrated. Then check the duct work, on some models there might be air ducts and deflectors. Often these either break or fall apart. Next is the thermo switch. I don't know if the TDI is equipped with a single, dual or even triple stage cooling fan. All three stages should work. The temperature(s) should be stamped on the body of the switch. If you have a continuity meter and thermometer, drop it in boiling water and see if it works.
