2.0L (B48) - M135i xDrive Performance
Petrol
Listen for any subtle clunking from the front suspension over speed bumps; while the xDrive system is robust, the adaptive dampers can occasionally show wear in vehicles with higher mileage.
Check the infotainment system by toggling through the iDrive settings; ensure the screen brightness and responsiveness are consistent, as some units have been known to show minor display quirks in varying climates.
During low-speed maneuvers, observe the transmission shifting; the Aisin 8-speed is generally excellent, but feeling for any hesitation during the 1st to 2nd gear change can provide insight into the condition of the transmission fluid.
Inspect the alloy wheels and brake rotors carefully; the M135i is a performance-oriented machine, so check for signs of spirited driving or uneven rotor wear that might indicate a need for a brake service sooner than expected.
Consider a proactive transmission fluid flush and check of the cooling system hoses for any signs of aging.
It's a good time to evaluate the suspension bushings and verify the integrity of the xDrive transfer case oil.
Keep up with the 'Condition Based Service' (CBS) indicators shown on your dash, as the B48 engine performs best with fresh, high-quality synthetic oil.
Check your brake pad life periodically, especially if you enjoy the twisty coastal roads of New Zealand.
Inspect the cabin air filter annually to ensure the climate control system remains fresh and pollen-free.
Monitor the coolant level occasionally, as modern turbocharged engines run warm and appreciate a healthy cooling system.
Regularly clean and treat the leather or Alcantara upholstery to keep the cabin feeling brand new for longer.
Estimated repair costs if issues arise
Given the M135i's performance capabilities, you might eventually need to budget for a complete brake set. It's a standard part of owning a high-performance vehicle in New Zealand.
If this component needs attention in the future, it is worth noting that adaptive suspension is more complex than standard setups. It's sensible to set aside a buffer for eventual damper servicing.
