Hello all you 1.8t oil warning light people.Today i took some photos of the oil pump strainer blockage,as you can see the new strainer is clear and the old one has the sludge deposits that block the oil feed and create the pressure problems and the noise from start up.This A4 also needed the sump steam cleaning out and the breather pipes de coking and i fitted the modified oil filter and jobs a good un. Hope you might solve the low oil pressure on your 2001 audi a4 with my tips.

Service solution

Check whether the engine has mechanical damage, for example through significant rattling noises. In this case repair accordingly.
If there are no signs of mechanical damage, only replace the oil intake strainer . A replacement of the complete oil pump is not necessary. An ****ysis of oil pumps has shown that sludging does not affect the oil pump operation.

Fit a bigger oil filter to increase the oil quantity (see ETKA) at the oil change service.

Production solution

Service solution

Check the oil pressure and compare it with the required values in the workshop manual. If there is pressure at idle speed, but it collapses at higher revs, remove the oil sump and check it for coking residues. If oil mesh and snorkel are coked-up, clean or replace them. Also take off and clean the valve cover.
After these measures change the oil. Repeat the oil change after 1000 km at the latest.

Bigger oil filter since November 2001.
