Last week my son bought an A4 Quattro with 109,000 miles on it. The engine sounds good & it drives fine. [There is a whine from the rearend, but another Audi owner told him that is normal. . . ? It was unlicensed so driving any distance before we bought it wasn't possible. ]
At about 180 degrees [oil temp] the oil light comes on. It goes off and on randomly after a few minutes. Somtimes it will stay on/off for a couple minutes, sometimes seconds. The water and oil temp stay steady, so I'm guessing that the light is lying and the lubrication is still working.
I've tried to see a pattern on what makes the light go on and off but accelleration, de-celleration, up hill, or down hill make no difference. It comes on regularly at 180 degrees-- but then it is completely random.
The car had been sitting for 4-5 months & still has the same oil in it. Tomorrow that gets changed.
It seems to be going on and off more frequently the more he drives it, but it still comes on regularly just as the oil reaches about 180 degrees.
I'm thinking that it is probably a clogged screen that is slowly unclogging itself-- or a sticky sending unit. Any other thoughts-- or a thought on how major a job dropping the pan is on this thing?
Thanks- Jim [This is my son's first car & though I tried to talk him out of it, the Audi is growing on me fast--- The sound of the doors shutting is a simple pleasure by itself.]
