Hello,


I have a 97 Audi quattro 1.8 turbo with 97,000 miles. The oil temperature indicator keeps turning on and off. I replaced the oil temperature with a genuine replacement. I also changed the oil and coolant but the issue continues. Does anyone have any hints as to what could be causing this?


Thanks,
Francisco

 

You sure its the temp and not the pressure light?

 

Yeah it's actually the pressure light. I changed the pressure switch and put in new oil plus a filter. The light is on while driving but it actually comes on when I come to a stop.

I took the pressure switch out and put in a pressure gauge. It's reading okay at 2k rpm although at idle it reads 10 PSI. It also currently has a tiny oil leak.

 

Well.. being an older 1.8 I would start looking into the "sludge" problem. Do a search on the board and google. You'll find tons of info.
