After posting,way bck in 2012,on the M hesitation thread,that my M Roadster didn't suffer this,as some others had.......
It started doing so last summer... Went to BMW Indy who initially couldn't find any issues,as no fault code came up,but after a couple of attempts at clearing DME etc,to see if it would resolve it,decided to renew a sensor in the exhaust manifold,which was not working correctly( running hot and cold),but this did not help much/any.
Fast forward to now,and it had been getting gradually worse,and more annoying...pulling out of junctions,roundabouts it would hesitate/bog down(not good),and then over rev and take off like a scalded cat....
Happy to say he then cleaned the Idle control valve,just recently,and the car is now FIXED...AND BACK TO ITS GOOD RUNNING SELF
Feels like it used to all the time/ until late last summer.....now a joy to drive all the time again,wooho.
I know this has been a fix for some,but not others.,.....worked for me though,so definitely worth a try.
