Great reliable car just been serviced and passed mot . Past services have been regular recently changed brake pads,discs and tires. 2 keys Parking sensors are faulty great on fuel 180bhp twin turbo The car has been very well maintained with regular servicing, quality oil changes, and careful driving. Like all BMW N47 engines, the timing chain is a known consideration, but there are no issues at present no noise, no warning signs, and it runs smoothly. Based on how well this car has been cared for, I'd expect at least another 30,000 miles before any chain work is likely to be needed, though of course this depends on future use.
