Need Help Audi S4 2002 B5
I just got a 2002 S4 and need some help. The car temp needle is dead center when driving but at idle sometimes it start to move half way to the hot side. The timing belt , water pump , all that was done at 75k there is 103k on the car now. What areas can I check, clean or replace? Could it be the thermostat not opening up all the way, could evap pump for the PVC be clogged? Any suggestions would be greatly appreciated. Also whatever pictures showing these items would be a HUGE help. Thanks

Check that all your fans are working. The thermostat "should" have been replaced also when the timing chain was replaced. The passenger side electric fan should engage when the A/C is turned on. The driver side electric "puller" fan is to assist the engine driven fan to cool the engine coolant. I believe it is a two speed fan. Could be a bad fan or just a fuse. I replaced the A/C fan on my 2000 S4 at 170K because the brushes were conpletely worn down and no longer contacting the commutator. Actually got the brushes from a junk yard '98 A4 fan and swapped them in for a $5.00 fix. No one had a new motor in stock.

Only real problem I had was getting the strap that surrounds the filter off. I had to use a 5mm allen key. It was working fine until the back part of the screw started to turn w/ the front part.. then I wasn't unscrewing anything. I had to cut through the middle of the screw and then when I put it all back together, I used tiewraps to keep it tight up there. other than that... not too bad.
