Audi 100

I recently had a question answered by Kebabmeister (i think) regarding the oil light flashing and a bleeper going when you went above 2000rpm. There is plenty of fresh oil in the engine, I tried disconnecting the pressure sender to see if that was faulty but it made no difference, the engine is the 2.6 V6 one is there an other switch other than the one next to the oil filter, hopefully somebody can help. The problem appears more annoying than serious as the car has done 10000 miles like this

If the oil warning light comes on it usually means a drop in oil pressure to below 5 bar, any lower, or continue driving and you risk blowing the engine, removing the pressure switch is a bad move, I would find out why it is coming on, i lost an engine at hig speed only a few seconds after the light came on, the pump had failed and this resulted in the engine losing its lubrication and the piston finding its way out throught the block, very messy and very final, I know of a guy who had a similar problen to yours, his oil light would come on and he would stop, then it would go out and off he went, this went of for quite some time until he went to a garage and they couldn't find any problems, and suggested he just ignore it, but leep an eye on the oil level, next time it came on , he ignored it and bang a few miles down the road his engine went bang.

Further inspection of the remains of the engine found that the sump was full of dirt and debris, they figured out that as the engine speed increased, the iol pump pumped harder and the dirty and debris was sucked up into the iol strainer, and actaully blocked it, causing a drop in pressure, a simple engine flush, with a new filter and fresh oil would have fixed the problem.
