Aftermarket options

Before you buy
Non-M M52TU/M54 only; M3 and M56 excluded. Match VIN and transmission, compare kit contents, and do not confuse the automatic-transmission heat-exchanger thermostat with the engine thermostat. Diagnose the failure before ordering. Cooling-system kit contents vary by engine, transmission, production date, and manual/automatic expansion-tank plumbing. Use the VIN and the exact kit bill of materials rather than treating a category page as universal fitment.
