check your oil level and pan plug. also,

check the your old oil filter o-ring did not stay
on the filter housing, when you installed the new filter this will cause an oil leak possibly a fire.

Did you use a cheap oil filter have seen cheaper oil filters cause problems with oil pressure

I havnt changed the oil filter actually because we changed the oil in a rush so we didn't have time we wer SUPPOSETO change it In a few days I don't think the oil filter has ever been changed car has done roughly 85,000 kms
Maybe that's what causes the oil button to flash before it turned off? Cause the filter is old or maybe too dirty ?

Re: Audi a4 b6 2002 2L
 

very possible! the oil filter has a filter element inside, that filters contaminants out of the oil, and keeps the oil clean. When the oil filter gets too dirty to filter, there is a bypass in the filter that allows dirty oil to pass through the filter, to the engine.

after the filter has plugged up, and the bypass opens the theory is... dirty oil is better than no oil.

I would change the oil filter and change the oil again. it may have plugged up and
cause a problem with oil pressure. which oil and filter change may or may not fix.

85,000 km is a long time to go without and a lube and filter.

good luck !

Thanks a lot for your help I'll let you know what the problem ends up being, it's currently with the mechanic.
And if it was the oil filter being dirty causing it to ruin the pressure would that cause it to not turn on anymore?

Re: Audi a4 b6 2002 2L
 

it would cause alot of problems, but I think it would still run, unless the engine seized. which would be bad. Honestly, I would have to see to diagnose the problem properly. I would be interested in knowing what the problem was though!

once again good luck!

Hi again, just letting you know my mechanic has checked it and it turned out to be the head that's gone. Still willing to change the oil filter too though .. Thanks a lot for your help :)

the particular acrylic filtering features a filtering component interior, which filter systems contaminants from the acrylic, and will keep the particular acrylic clean. If your acrylic filtering gets also filthy to be able to filtering, there is a get around inside the filtering which allows filthy acrylic to feed the particular filtering, to the serp.
