Sick M diagnosed- costly!

Post by d0mokun » Fri 29 Jul, 2011 12:44

Hi chaps,

Yesterday I had my M diagnosed by a BMW dealer in order to work out why the car is unhappy- it often goes into limp mode, often throws the ECU/ emissions/ traction light, and often runs a little rough.

Turns out that a new manifold potentiometer is required, along with a significant amount of labour time (and cost) to get it installed. Bad karma, man.

Is this a common fault or have I just drawn the short straw?

sorry to hear that mate. shouldnt be that expensive if you take it to a good independant mechanic and try and source the part from a written off M, according to the statistics there are quite a few of them :? I havent heard your problem that much happening to the M so must be bad luck.

Get a second opinion

"Understeer is when you hit the wall with the front of the car, oversteer is when you hit the wall with the rear of the car. Horsepower is how fast you hit the wall and torque is how far you take the wall with you"
