2.5L V6 (M272)
Petrol
Check engine cold start for rattling | Note: The M272 engine is notorious for balance shaft gear wear. Listen for a distinct rattle or check for P0016/P0017 OBD codes.
Observe coolant temperature needle | Note: Thermostat failures are common; if the needle doesn't reach the middle promptly, the engine runs rich, leading to poor fuel economy.
Verify smooth gear changes | Note: The 7G-Tronic transmission needs clean fluid. Hesitation or 'thumping' between 1st and 2nd gear indicates valve body or conductor plate issues.
Inspect interior trim and electronics | Note: Check that the COMAND system and seat adjusters function properly, as SAM (Signal Acquisition Module) modules are prone to moisture-related faults.
