Just planning a few preventative maintenance operations and was wondering about peoples experience with the oil pick up pipe problem.
My A4 1.8t (190) is coming up to 99k miles. It has had regular oil changes every 7.5k miles (along with spark plugs, air filter) How succeptable would you expect this car to be to the sludge in the oil pick up pipe? If i increase the oil changes to every 5k miles do you think i can avoid the problem?
It's due an oil change next week and i was going to put the larger transporter oil filter on giving the increase in oil capacity, is this filter a definate fit on this engine? filter reference 501440080, or would people recommend just going with the slightly larger filter reference 068115561F?
I was doing to do an engine flush at the same time, is this advisable? would this just likely dislodge any sludge and make any existing problem worse? Should i flush it twice?
Also if i do go the whole hog and get the pick up pipe replaced, is it advisable to replace the oil pump at the same time? Is it ok to keep the same pump?
