new to m5 ownership so not to good with before and after here is problem no 1
when engine is cold there is some kind of fast idle program coupled with this there is a decernable hold of revs noticeable as you change gear this reduces as the engine warms up in time with the lights going out in the rev counter when warmed up everything is fine
if i fill up with shell optimax there is a definite improvement in running compared to other super unleaded fuels
what is the piont in having all this power if every time you accelerate the traction control cuts in if you turn it off the only way round a corner is looking out the passenger window
