: knocking and fan squeak

I have a 2008 Q7 Premium 3.6 S-line and love it! But, when I start the car cold, there is a slight knocking sound in the dash. Also, when the climate control is on auto and the car comes up to temp, there is an annyoing squeaking (sounds like a fan) on the passenger side. Any advice? Anyone out there ever change a rear 12V plug? My cap broke and my slack dealer sent me the insert and said it was a "breeze" to install...nice.

I think they all like that. it's take a few seconds for the oil pump to do its job. My 08 Q7 also loud when I started cold.

Did you ever get it resolved?

I had a fan squeek as well. There is a nice tutorial on youtube how to take the fan apart and lube it.. took me 1 hour and that annoying squeek is now gone. All you need is a Torx15 and a 5.5mm socket.
