Justin, sorry to hijack. We've had a bit of a chinwag via pm on another forum about MAF's though.

I would be very interested at a pair of housed MAF's for £250 Cemessi.

Problem is i can't pm as my post count is too low!

Could you post on here or pm me details if you don't mind mate?

I've looked into that, and came to conclusion didn't have one?!
If I thought it had one would have checked that first - searching I've done hasn't indicated it's had one.
Another is TPS, I know on my M3 it was an insp2 item, doesn't appear to be one on this though...?

Justin, i'm sure its under the inlet plenum mate. I had mine off last night to renew the fuel breather valve and am sure i saw it.

Bit of a pita to access though as you have to undo about 60 nuts/bolts to whip the inlet off.

An hour will easy see you right in whipping it off though.

Bloody hell, I'd have checked that ages ago if I'd known!
Previously looked on realoem to see if I could find one too.

Found it now!

Have to look at this soon now weathers above freezing!
Can't believe all the hours on google didn't return ICV - just like on other cars I've had, but discounted it having one due to this.
Thanks everyone, will update when I've had a look at it

Well to update it's still doing it.

hi
it sounds as if it only happens when you remove your foot from the accelerator?
It is possible that it can be the throttle position sensor? Don't know why the car will stall though.
Cheers

This is another thing - the 3.0 M3 I had the TPS was an insp2 item, yet never seen a mention of these being changed on the M5?
Have to do more digging on that one
