2.0L M266 I4 Turbo - B 200 Turbo
Petrol
Check the CVT gearbox responsiveness by accelerating gently from a standstill. | Note: It is common in the W245 series to experience shuddering; listen for inconsistent revs or hesitation, as the Autotronic transmission may eventually require professional attention.
Operate the panoramic sunroof through its full cycle while the vehicle is stationary. | Note: These complex mechanisms often require periodic lubrication; ensure there are no grinding noises or signs of water ingress around the headliner during wet weather checks.
Listen for a rhythmic 'ticking' or 'rattling' sound while the engine is at idle. | Note: The M266 turbo unit benefits from regular oil changes to keep the timing chain tensioner healthy; sounds that persist after warming up are worth discussing with a local specialist.
Observe the instrument cluster for any warning lights, specifically steering or stability control icons. | Note: The steering angle sensors on these models can occasionally report faults due to age-related electrical wear, so verify that the steering feels consistent and error-free.
Consider a full transmission fluid and filter service to ensure the CVT longevity.
It is wise to inspect the cooling system hoses and the water pump for any signs of perishing.
Typically a good interval to have a specialist check the turbocharger housing and intake seals.
Verify the service history specifically for high-quality synthetic oil usage.
Inspect the condition of the cabin air filter to ensure the climate control operates efficiently.
Check the brake pads and rotors, as these can wear slightly faster due to the vehicle's weight.
Test all electronic seat adjustments to ensure the motors are tracking smoothly.
Confirm that the battery holds a stable charge, as the W245 electronics are sensitive to voltage drops.
Estimated repair costs if issues arise
While the Autotronic transmission is clever, it does require specific fluid changes to stay smooth. If the vehicle hasn't had this done recently, it's good practice to set aside funds for a specialist service.
Given the turbo setup, rubber lines and gaskets can become brittle over time. If you notice a loss in boost or an oily residue in the engine bay, you may eventually need to budget for a refresh of these seals.
With NZ road conditions, rubber suspension components can wear out over many years. You might eventually notice a slight clunk over bumps, which is a sign it's time to refresh the bushings.
