Just felt I should post some infomation about the F10 M5 that all owners should know about!! I have a 2012 M5 with 45000 miles on the clock, one day it started making a horrible turbo whine/squeel noise under hard accelleration so the car was booked into maindealers for investigation. 1st visit to BMW 2days couldnt find the cause but contacted BMW for advise. 2nd visit 3days still found no cause for problem. 3rd visit to BMW they requested the car for 10 days to make sure they had time find and sort the problem? its now been there 37days and counting!!!!!! failed turbo was found to be the problem so BMW agreed to fit two new turbo's under warantee, Great I thought brand new turbo's and should have car back in around 14days. this is where it all begins, turbos on back order sir will be next week before we can get them here. three times I was fobbed off with they will be here next week sir before they finally admitted they cannot get me the turbo's and they have no date for when they will be able to get them!!! they no longer fit this type of turbo sir, were sorry etc etc. I have so far been loaned an X1 18d a 320d X drive tourer and at min only due to constant complaining about when will I get my £80K M5 back they have lent me a 530d tourer and have generously told me theres no rush to get it back and I can use it for as long as necissary as its been loaned from BMW UK not the repairing dealership! All owners of the mighty M5 need to be very aware and concerned that despite the huge price tag of buying and running the M5 BMW are not bothering to carry the spares to honour the waranty they sell you with the car!!!!!! My car went into Stratstone BMW derby on 5th Nov 2014 and its now looking like being sometime in 2015 before I get my car back and theres no date as yet for them getting the parts. BMW and M cars are clearly not the great brand they once were! bring back the e30 days:crying:
