2.0L (M35i xDrive) - High-performance M-Performance variant
Petrol
Spend a few minutes in heavy stop-start traffic to check for any jerkiness in the 7-speed dual-clutch transmission; while usually smooth, some minor hesitancy can occasionally occur as the system adapts to your driving style.
Navigate over some uneven NZ backroads to ensure the adaptive M suspension feels composed. Listen for any persistent knocking sounds, as the complex suspension geometry in the U11 can be sensitive to heavy impacts.
Before your drive, toggle through the 'My Modes' settings on the curved display to ensure the system is responsive and that there are no software lag spikes, which can occasionally happen with the iDrive 9 operating system.
During the inspection, check the inner edges of the performance tyres for uneven wear, as the xDrive system and the M35i's aggressive factory alignment can sometimes cause tyres to reach their end of life sooner than expected.
Usually involves a standard engine oil and microfilter service, plus a visual check of the xDrive drivetrain components.
Often when you would consider a more comprehensive service including spark plug replacement and potentially brake fluid flushing to maintain peak performance.
Typically the stage where you might start looking at a full transmission fluid service to ensure the dual-clutch system continues to provide crisp shifts.
Keep a close eye on your oil levels between scheduled services, especially given the high-output nature of the B48 engine.
Ensure the coolant levels are monitored as part of your regular under-bonnet visual checks.
Regularly clean the camera lenses and sensors for the Driving Assistant features to ensure the advanced safety systems remain accurate.
Check the tyre pressure monthly, specifically using the recommended pressures inside the driver's door jam to help preserve the performance rubber.
Update the vehicle software whenever a notification appears on the iDrive screen to keep the connectivity features running smoothly.
Estimated repair costs if issues arise
Future Budget Planning: Because the M35i is a performance variant, the brakes are designed for stopping power; eventually, you might need to budget for high-performance pads and rotors once they reach their wear limit.
Future Budget Planning: High-performance tyres provide the grip necessary for the M-tuned chassis, but they can wear faster than standard tyres; it is wise to set aside funds for a quality replacement set every few years.
Future Budget Planning: To keep the shifts crisp in the long term, you might eventually need to budget for a professional transmission fluid and filter change to ensure longevity of the gearbox internals.
