One problem related to instrument panel has been reported for the 2006 BMW 325. The most recently reported issues are listed below.
Since I purchased my BMW 325i (2006) in Aug. 2007 new, I have had problems with a 10% inaccuracy of the speedometer, that the dealership reluctantly replaced (with no improvement) and BMW of north America finally admitting that there is no solution to the problem and I was stuck with the problem. The speedometer is 10% off an actual reading. So if you want to 65 mph and set the speedometer at 65mph you only go 58 mph. In order to go 65mph you have to drive at 73 mph on the speedometer.
