stalling at a stop and when accelerating

[craigellis]

Hello All, I have recently brought a 2007 630i, it has started to stall when i pull to a stop at lights or about to start pulling away, the garage has said they can't find any fault codes and they are a little baffled has anyone else had this problem?

Hi Craig

Welcome to the Forum

You need someone with BMW diagnostic software to scan the car, there is a Register of BMW Specialists Google and find the nearest to you.

Unless you are able to DIY? If you are then get yourself a copy of BMW INPA/ISTA or Carly for BMW, iCarsoft or Autologic the investment will save you a fortune in the long run

Your stalling could be a clogged fuel filter, failing fuel pump, MAF sensor, Throttle body the list is long so diagnostics are important.

Nice Car

Have a look for a split in the air intake after the maf sensor. It would cause stalling as the engine would run lean. Also check throttle position sensor and perform a reset and test. 
sound like an idle issue caused by incorrect air flow. 
unplug the maf and see what happens
