Question about 1999 Audi A6
I have a 1999 Audi A6. The aux fan that goes on when the car is first started works fine except it is VERY loud. Sounds like the motor bearings are bad. I know this is a common problem for this model. I would like to replace. It is in a tight location. Any advice/pictures/ youtube videos on the easiest way to replace would be greatly appreciated. Thank you in advance for your help.

The guage and fan speeds work on independant sensors. If you can remove the plastic engine cover and locate the "sending unit" for the gauge disconnect it and restart the engine. The gauge should remain cold and not move. If this is the case replace the sending unit. This should be a single wire sender located in the waterjacket of the intake manifold look in the area where the upper rad hose enters the intake.

Sounds like the gas presser valve or weak fuel pump. When it dose it again turn the switch on and leave it on for about 3 mins. and see if it will start. If it dose I would say the pump is weak.

Have you checked to see if there is spark at the plugs? If not, simply take out 1 plug (can be any one of them), connect the plug wire to it and just let the threads of the plug rest anywhere on the engine block. Have someone turn the motor over while you are looking at the gap on the spark plug. If your distributor is sending sufficient power, you should see a nice healthy spark! If no spark, then your problem is either bad coil, bad distributor, distributor cap, rotor, or ignition. But first things first, check to see if you are getting spark.
