After consulting with BMW and obtaining a key printout, it would seem the fault centres around 3 possible issues 1. Oil in the diff (lack of oil maybe the problem) 2. Possible wheel bearing malfunction (loudest whine is when I make a right turn) 3. Fault with the speed sensor resulting in other electronic functions (cruise control, stability control, abs, brakes) appearing on the dashboard as faults Due to the distances travelled, it is important for me to get an idea that these can be sorted out in a day, the price range before committing to driving there Vehicle is a 2012 F30 BMW 320i luxury line automatic with 143000km on the clock Vin is NP41369
