2006 Audi A4 Quattro (Knocking)
I have a 2006 Audi A4 2.0T Quattro
Every time I turn on the vehicle and I hear knocking
I recently replace the radiator with a brand new one
and a water pump sure it doesn't have anything to
Do with one of those.
I have a couple of videos.
But I've been told it's "normal" but it doesn't sound
No I would not think it is normal. If you have isolated the sound to the engine, and not coming from anywhere else, like the exhaust or something, then it could be a rod knock.
ill have to look more into it thank you Rowefast
check your timing chains as well, any rattling during startup could indicate needs to be replaced soon... that will cost well over $1k in parts and much more in labor, as it requires an engine pull.
