#19 of 24 Oil pressure light coming on...among other things by dianebou Jun 18, 2007 (12:28 pm)
I am new Audi owner of a pre-owned 2001 TT Quattro (sedan). It's a manual 5-speed. I am experiencing several problems, the first (and most alarming) of which my mechanic has no solution for.   --The oil pressure warning light comes on intermittently, just about every time I drive the car. It seems to happen in a couple of different circumstances: a) When I am coming off the highway after being in 5th, and must come to a stop at the end of the ramp. Then, it will go off again when I move forward, but will come on again relentlessly every time I must come to a stop; b) when I encounter a lot of stop-and-go traffic and continually accelerate/decelerate.   In the 2nd instance, recently, I was driving in the city, in extremely heavy traffic, and the oil pressure light went on and off continuously. Not only that, but the engine started to overheat.   I have checked the oil, and the level seems fine. Also, I am using the highest quality synthetic oil available (according to my mechanic...I couldn't tell you what kind specifically).   Is this an oil pressure problem? How serious is it? (i.e., how expensive?) Thanks so much for your help! Replies to this message: Mr_Shiftright (Jun 18, 2007 12:48 pm)

Replying to: dianebou (Jun 18, 2007 12:28 pm) Well you might have to install (temporarily) an analog oil gauge (one with numbers) to read what's going on, to make sure it's not just a loose wire grounding out. If the gauge drops every time you maneuver, then that is a bit troubling. Possibly you have some kind of blockage or malfunction to the oil pump pickup screen, or a broken baffle in the oil pan (that should keep the oil from sloshing around in there).   So I'd check for a loose wire or bad sensor first off, then screw in an analog gauge for testing.

Replying to: joepablo (May 03, 2008 8:00 am) One thing about Audi engines, you MUST use the OEM oil filters or exact equivalent to assure that you don't get funny lifter noises. Apparently, some off-brand oil filters aerate the oil, and the lifters tend to collapse.   Before digging into the engine by all means go buy an AUDI filter and the oil weight recommended in your owner's manual and see if this corrects your problem.
#23 of 24 im using fram and its doing fine by savannah_tt May 28, 2008 (3:25 pm)
my 2001 uses no oil and it has 74K. (225hp) i guess im lucky. the fram filter is working fine with no oil light probs.fyi there is like 3 fram filters that fit the car. one is for the VW's one for audi and one is just huge that some use for higher oil capacity.

Replying to: savannah_tt (May 28, 2008 3:25 pm) I think the V-6 is more susceptible to non-factory oil filters, from the reading I've been doing on the subject.   If the non factory oil filter is causing problem, you'd know it. The car would either run badly or not at all. It might not even start. One has to see a non-start Audi cured simply by replacing an oil filter to believe such a thing is possible, but I lost a bet with a mechanic on that very incident.
