Thanks. Although, I have acknowledged a problem to BMW, when they get it and analyse it the ECU is not reporting any faults, so BMW are not saying anything is wrong with the car. I have resorted to taking photos of the iDrive display when a fault comes up to prove that I am experiencing problems.
I was hoping to be able to glean some expert advice from you guys so I could print off a list of things which I wanted them to check! Thanks so far for the help.... any more ideas? Look forward to hearing the outcome from bobst
