Inspection checklist
M6 F13, 2012 to 2019
Before you go
- Open recalls. Run the VIN through NHTSA or a BMW dealer and ask for proof every recall was done.
- History report. Check the title, accidents, owners and mileage record.
- Service records. Ask for them in advance, ideally from a BMW dealer or specialist.
- Independent inspection. Book a pre-purchase inspection with a shop that knows this engine.
Known problems on this car
- Fuel injectors and high-pressure fuel pumps about $2,500 to fix
Ask for injector and pump history and scan for misfire and fuel pressure faults.
- Turbo coolant line leaks about $2,000 to fix
Confirm by VIN that the turbo coolant line service action (SI B11 08 17) was done, look for cooling work in the records, and watch the temperatures on the test drive.
- Rod bearing wear about $5,000 to fix
Ask whether the rod bearings have been replaced, look at oil analysis, and treat a tune or track use as a reason for caution.
- Carbon buildup about $800 to fix
Ask about mileage and whether walnut blasting has been performed.
At the viewing
- Injector and high-pressure fuel pump history and a scan for misfire and fuel pressure faults.
- A VIN check that the turbo coolant line service action (SI B11 08 17) and the recalls are done (the oil pump on some early 2013 cars, the driveshaft on some late-2014-built 2015 cars, the third brake light on every Gran Coupe).
- Rod bearing records or oil analysis.
- A clean-shifting gearbox.
- A documented and untuned car.
- The condition of carbon ceramic brakes where fitted.
