Hey all,

I bought a 2007 X5 3.0si a couple months back. Along with a couple other issues, I'm getting occasional "blips" or dips in the RPMs. They only seem to show up when in gear and at idle (ie when stopped at red lights). The blips aren't triggering any CELs and I'd say are nuisance more than anything else. I recently replaced both Vanos solenoids with genuine OEM BMW hoping that might help. Although my fuel economy has improved significantly since, the blips still persist.

Any ideas where to look next?

Thanks in advance,

Cedric
