Hi all hope you can help.
Just bought a Mini Cooper d 2010 March and its got a stutter did some googling and then disconnected the maf sensor car then runs fine with maf unplugged thought yes I’ve found my fault so bought a new maf sensor fitted it and arghhh it still stutters at low revs. Confusing me as it runs perfect with maf unplugged but puts the engine light on. Really hope some of you can help.
Thanks
John

Could it be that when the maf is unplugged it bypasses the egr valve I’m wondering if egr valve is sticking open as when I checked codes egr valve was there. Thanks for your reply mike just wanting to try other things before spending £3/400 on a dealer maf
