Finally got our X5 back after over 2 weeks waiting on a replacement Bridgestone 315x35x20 Run flat tyre.

My original request was for the dealer to replace all 4 with a tyre brand that they could source e.g. Dunlops but they responded that the Bridgestone is arriving within the week - they didn't say which week!

I was provided with the dealers rental X5 for the entire duration and BMW UK paid the dealer the rental fee for this period. At £770/week!! I reckon the dealer could have returned my car within 2 days had they opted to replace all 4 tyres. Average cost of a tyre would be £300, plus one happy customer back on the road.

In fairness BMW kept us on the road in an X5. Thing is I didn't pay to drive around in someone elses X5 and quite frankly it was embarrassing after a week never mind 2 weeks to have to tell people that I was still waiting on a new tyre. BMW also choose to ignore the technical info that could have seen the puncture repaired. Overall it has been a very dissappointing experience and it may not be over yet. I have not seen the car yet as I work away from home but I am informed that they have scratched the wheel rim replacing the tyre.

Am I being unreasonable to expect BMW to have the most up to date technical information on RFT technology (and the repairs thereof), for BMW to be able to replace a tyre within a reasonable time - I would suggest 48hrs as reasonable and for BMW to take more notice of customer satisfaction in after sales?

It's a great car but not such a great company.
