Changed the oil this weekend on my 1.8T BEX. It's been changed every 9k miles with Mobil 1 5W30 for the last 90k miles. Car is currently at 160k. I've owned the car for 11 years. Sadly found some unwelcome objects in the oil for the first time. Black plastic, with score marks. Very small. I am 98% sure these objects are from the oil pump chain tensioner (because they are coloured black, not brown like the cam chain tensioner, and because they have score marks likely from the oil pump chain). This is a file photo of the oil pump chain tensioner: In situ: Some other guys' broken one which he found after stripping an engine (he had no symptoms). I think mine has broken in the same way (going on the dimensions of the deposit of plastic bits in mine): I have (touch wood) no oil pressure light at any speed or idle. No ticking or rattling. It's a major job getting to the tensioner, way beyond me, and decently beyond economical repair given the car is worth around a grand (whole of the front of the engine has to be removed). So since finding only small bits I'm sat here telling myself that only a small section has broken away and flushed out, and that the tensioner will not continue to disintegrate, and my oil pickup screen is surely clear. That the Gods will continue to smile and the 200k dream is still alive. Does Audi-Sport concur?
