I bought Used Audi A4-2.0 issues right from get go..low oil 1 quart. Took car to Audi dealer they inspected it for me. Everything looks great! 9500 miles later check engine light comes on. Take to Mechanic to run code. Code is saying belt slippage. Took to dealer right away. Waterpump, timing belt replaced. Noticed timing not correct still so they tore valve covers off, replaced timing chains and tensioners. Found debris in screens around cam gear. Found debris in oil pan from oil filter? Changed oil with only synthetic oil every 3000 miles so i dont get it?
I am out $2500.00 dollars still and car in shop still with timing problems? Done with AUDI buy a BMW with timing chain and dependable.
Had timing belt replaced at about 120,000 miles on dealer advice. Engine immediately had a higher pitched whine and several thousand miles later the engine oil symbol flashes and several blocks later the engine is toast. Local garage says it looks like the timing belt. Have it hauled to the Audi dealer and they claim its the oil pump.
