Observe the gear shifts while moving from a standstill. | Description: The 9G-TRONIC transmission is generally robust, but some owners report occasional hesitation. Ensure the changes feel seamless and not jerky under gentle acceleration.
Operate the Vario-Roof through a full cycle while parked. | Description: Check that the roof latches and unlatches without excessive groaning. Ensure there are no warning lights on the dash once the operation is complete, as microswitches can occasionally get grumpy with age.
Listen closely for any rattling sounds coming from the timing chain area during a cold start. | Description: While the M274 engine is solid, it is common to consider the health of the timing chain tensioner in higher mileage units to ensure everything stays in time.
Inspect the interior door seals and the boot lid area for signs of water ingress. | Description: Check for any dampness in the boot carpet. It's a good practice to ensure the roof seals have been looked after to keep the cabin dry.
