I see that cracked 19"alloy wheels have been causing problems for BMW owners for some time. My car recently failed its first MOT due to three cracked wheels. Two were within BMW's limit and one not. No one has been able to explain how this limit was calculated and I am left feeling angry at having to pay £400 plus VAT for the one wheel that was deemed to have been 'damaged' by me. The dealership was very helpful and indeed sympathetic to my complaint. I called BMW customer services and was told that “after investigation” (i.e. calling the dealership to check that I had given them accurate details), “the complaint was considered to have been dealt with and that it could not be escalated further". Charming.
