AMG A45 S 4MATIC+ 2.0L Petrol - AWD
Petrol
While cruising at lower speeds, listen for any 'clunking' from the suspension, as the adaptive dampers on these AMG models can be sensitive to New Zealand's varied road surfaces over time.
Check the MBUX infotainment system by cycling through the menus; ensuring the touchpads and voice commands are responsive is important as these sophisticated systems can occasionally require software updates.
Observe the transmission shifting from a cold start; the 8-speed dual-clutch gearbox should engage smoothly, as jerky shifts in these high-output performance engines are worth investigating with a pre-purchase inspection.
Inspect the alloy wheels and tyre sidewalls for 'kerb rash' or uneven wear, as the A45 S is often driven spiritedly, and alignment issues are common in performance-tuned setups.
Usually the time for the first major brake fluid flush and a comprehensive inspection of the AWD drivetrain components.
A significant service interval where the transmission fluid and filter service is typically recommended to keep the dual-clutch shifting crisply.
Consider having the spark plugs replaced and a thorough check of the turbocharger cooling lines to ensure the 2.0L engine continues to perform at its peak.
Stick to the strict Mercedes-Benz service intervals, as the high-output M139 engine relies heavily on premium, fresh oil.
Keep an eye on your tyre tread depth, as the 4MATIC+ system performs best when all four tyres have consistent, high-quality rubber.
Every six months, treat the interior leather and trim with a quality protectant to keep the cabin looking as sharp as the day it left the showroom.
Regularly check your coolant and brake fluid levels between services to ensure the engine and performance braking system stay within their optimal operating range.
When parking, try to keep the vehicle away from heavy grit or road debris, as the performance brake rotors and pads can be sensitive to trapped foreign materials.
Estimated repair costs if issues arise
Given the stopping power required for the A45 S, the high-performance braking components will naturally wear faster than a standard car. You might eventually need to budget for a complete set replacement as part of your long-term ownership plan.
If the suspension starts to feel less composed or if a damper seal begins to weep, it is common to consider replacing them in pairs to maintain the car's refined AMG handling characteristics.
To keep the dual-clutch transmission shifting smoothly for years to come, it is common to plan for this specialized service at the 60,000km mark to clear out old fluid and ensure the clutch packs remain healthy.
