As you do I had the X5M in for Its MOT and mentioned the problem with reduced engine power that came up on the CIC screen about a week ago and also the indicator repeater in the near side wing looked like it had been pushed in. So the end car went in Wednesday night.
Then on Thursday I get a call from BMW to say they have investigated and the sensor is reading a fault. It could be the spark plug or ignition coil or possibly an injector on cylinder 3 on my petrol V8. So they are ordering a spark plug and ignition coil for it d then they will MOT the car after due to the emissions. They had now reseated the indicator and it was no okay.
Today, Friday I get a call and they have fitted the the new spark plug and ignition coil and it is still reading a fault on the car and so they are now ordering a complete set of 8 injectors for the car. These will be here Monday and I have been assured once they are fitted it will again be running at full power and then the car can be MOT'd.
So I am glad I got the car with the BMW comprehensive insured warranty as it should cover the cost as only done about 2,000 miles since I got it as its a weekend car

Roll on Monday
