Fixed my problem and charged me nothing

Thank you very much Andy and Rob. I was advised by another brake specialist that my BMW didn't have warped discs but it was the drive shaft which will probably need replacing as the rubber boots had split/come loose. Cost circa £1500. I took the car to Deepdale Service Station and they replaced the clips, serviced the drive shaft and test-drove the car to make sure everything was as it should be. The car problem (vibration) has been rectified. They charged me £0. These guys are awesome. Already booked my car in for its next service. Top quality. Top service. Top guys. Highly recommended.
