Hello,
I have an Audi Q5 3.2 FSI from 2011. I’ve got this weird problem with how my engine sounds after cold start.
After cold start I can hear a rattle/clicking noise for like a second or two. The sound speeds up with the revs and settles after revs go down as in the video. In the video you can kind of hear the speeding up of this rattle, but it is mostly clear after I let go off the throttle. Engine also misfires on cold. Once it went quickly to 600rpm after operating on ~1200rpm, it didn’t stall but it was jerking and „popped” like 3/4 times from the exhaust. Any suggestions? No codes.
