I have had this problem off and on in almost three years. First it was warped front discs, had them skimmed which gave a marked improvement. About 12 months later same problem, this time discs and pads replaced, again marked improvement. Recently feedback on brake pedal and steering gave the impression of brake problem again which really pi**ed me off. The car has passed its MOT with no problem. I went back to my mechanic conveying my frustration, he identified a problem with front upper suspension arm, I told him to replace both n/s and o/s. What a difference the braking and steering is so smooth, like a new car 😊 thought i would share in case anyone else has a similar problem.

Hi did you ever get this problem resolved?

Thank you ! I have just ordered a replacement starter motor, will see what happens once it is fitted.  

Hi Jim, An excellent and likely diagnosis of the cause. I'm grateful to you. I am encouraged in that there are no messages on the on board computer which is not slow in coming foreward on just about every possible topic - except this one !! So if it is real, cannot be serious. The car is running fantastically well, recently serviced plus gearbox with new sump pan etc., I usually achieve on a run of mixed roads 32 - 34 mpg, as shown on the onboard computer. Thanks again Jim, Kind regards   Dominic
