Oil light came on. Immediately pulled over and checked engine oil level. Not low. Took the car to the dealership. Originally diagnosed as needing a new oil pump due to oil sludge. On further inspection the dealer found scarring on the engine bearings and wear on the camshaft. Upon flushing all the pre-existing oil out of the engine, metal filings were found. New diagnosis: completely new engine required. Audi, USA knows this is a prombem with A4 1. 8t. They've extended warranties as a direct result. Yet becuase I'm the second owner and can't produce all previous oil change receipts, I'm being required to pay for the new engine. This is a poor engine design that I shouldn't be held liable for.
Audi A4 1. 8t oil pump failure causes cam adjuster failure, causing possible $8000 in damage to cams in 1. 8t motor.
