Red oil pressure warning

mekyjesy · 11-08-2011, 12:15 PM

Hello all,
I have been getting intermittent oil pressure warning on the dash. It is the red oil can and it beeps three times then goes away. I just replace the oil pressure sensor to see if that was the issue but I guess not. It takes about 20 miles or more for it to activate the warning, then it will go on and off with no specific duration. When the warning sounds, the vehicle is stopped, then restarted and it seems to be fine for a while. The light never seems to stay on, as after the three beeps it turns off and no indication on the dash. I've read about the o rings at the oil pump being a probable cause for pressure issues. Does this sound like the case? Where are these o rings and where is a good place to order them from? Does the pan need dropped to get to these rings? How many are there to replace?
The vehicle is an '03 A6 3.0 engine with 160K miles.

By the way I have been using 5W-30 oil in it since forever. Should I try a heavier oil with this many miles? Is so what should I use?

You may want to stop driving it. 1.8T and 3.0 cars seem to have an issue where the oil pickup tube will become blocked. Will start with the red oil light occasionally, especially when hot or drivin awhile. You need to drop the lower oil pan (easy as hell) remove the oil pickup and inspect and clean it, or replace it. You WILL destroy the engine soon if you ignore it. I have seen and repaired several of these engines with this exact issue. So address it quickly
