2003 BMW 5 Series Sedan 530i 4dr Sedan (3.0L 6cyl 5M)
Electronic Problems
 We picked up A CPO 530i just off of lease. Records were clean & initially car lived up to the BMW standards. 3 months in the electrical system started going haywire (sensors) & has been a pain ever since. It has gotten to the point I contacted the CEO of BMWAG in Germany. Very disappointed they threw it back on dealer. It is the mfg. fault, not the dealer. At present working with dealer to roll out into another. Dealer is being very helpful & I hope for a resolution soon. Other than this the car is what you expect from a BMW.
