Congrats on your M135i - you will love it 
Cold start-up...

Harkes,
Sounds great.
Ref your comment about no CEL light, how many km's have driven with decat DP so far ?
Sometimes CEL may take awhile to light up. I ask out of curiousity as I've heard mixed stories about whther or not decat and sports cat DP's cause CEL.
Anyhow, Enjoy !
