Have 2001 Audi A4 Quattro 1.8 lit turbo engine light on lost power and extremely loud ticking.
sounds like something broke. see if you can check the timing belt this is most likely the culprit. luckily the 1.8 won't damage the valves if the belt breaks. to check the timing belt just remove a cover from the front of the engine. and get your codes read.
