Hi Folks, Please, before you moan at me I really cant find the answers I am looking for and think that I have a "not that common" problem with my S3 oil pressure, in a way I hope I am wrong but we will see. I recently bought my 2000 plate S3 from a one owner from new and full every bit of history that you can think of incl full audi service history using long life all the way up to its stratospheric 220k miles that it has. I had the 3 beeps and it started to sound like an old fiesta so the story begins... It only happens when warm, never when cold and the real unusual thing is it generally happens after a little squirt of acceleration (not even that hard) and on back off the throttle and the revs drop below 2000 RPM... once left overnight and cooled it is fine again until warm and the above happens. I know that this sounds like the usual "below 2k rpm" but cant find anything about the "after acceleration and backing down the revs" bit or it just randomly happens. I have had the pressure switch replaced and no joy had the sump off and OMG the gauze was chock full "no exaggeration" so really thought that would help... but no, its worse! What next guys? I have seen threads talking about PRVs, big ends, oil pumps etc etc but not sure what to try next... The thing that concerns me is that it tends to only happen when warm, usually induced after some semi hard acceleration and then only when the revs drop below 2k but it also happens when I drive like a granny (most of the time) on straights and bends. Sound like a return flow issue? when it cools and also when cold the oil flows well, the tappets fill and it is fine for a while. One last thing, it is on long life oil and has been for its entire 220k life, could this cause this? Sorry if it is going over old ground but really hope you guys are patient and have some good advice. Thanks in advance, Neil.
