Timely maintenance is essential for any vehicle, but especially for high-performance AMG models like the ML63. Neglecting it can lead to some pretty significant issues down the road. So, let’s dive in!
Mercedes ML63 Essential Maintenance Tips
Regular Servicing: Maintenance is key to keeping your ML63 AMG in top condition3. Sticking to a regular service schedule will help prevent major issues down the road.
Full-Service History: When purchasing an ML63 AMG, look for one with a full-service history4. This indicates that the car has been well-maintained.
Engine Issues: The M157 bi-turbo V8 engine in the GL63 AMG (similar to the ML63 AMG) is known to have some problems.
Plastic Coolant Lines: The engine has small plastic coolant lines that are prone to failure, so keep an eye on them.
Cam Covers: Front cam covers tend to leak and may need to be buffed and resealed.
Cam Adjusters and Cylinder Liners: The cylinder liners, particularly on cylinder number five, can develop scoring over time, leading to low compression and misfires
Oil Changes: Use race oil, which may help the engine run and last longer
Air Suspension: Many ML63 AMG models have air suspension8. Be aware of potential repair costs as the car ages.
Link Arms: Check the link arms connected to the ride height sensors; they can wear out and cause the rear end to sit lower9…. Replacing these can solve ride height issues.
Brakes: Regularly inspect the brakes and replace worn pads and rotors.
Tires: Check tire date codes to ensure they are not too old.
Lug Bolts: Replace security socket-style lug bolts with standard ones to avoid issues during servicing.
Be Prepared for Expenses: AMG models are high-performance vehicles with high-performance price tags7. Repairs can be expensive, so set aside a budget for potential issues.
Proper Warm-Up: The presenter of the “Brothers On A Budget” YouTube channel suggests that letting the car warm up is a great habit to get into.
Mercedes-Benz ML63 AMG Potential Issues to Monitor
Engine Problems: Keep an eye out for low compression, misfires, and unusual noises, as these could indicate issues with the cylinder liners or other engine components.
Air Suspension Problems: If the rear end of the vehicle is sagging, inspect the link arms.
Oil Leaks: Check for oil leaks, especially around the axle seals.
Brake Wear: Monitor brake pad and rotor thickness and replace as needed.
MPG: Expect around 18 mpg.
Service Costs: High4. Services can range from £170+VAT to £270+VAT, excluding additional items like gearbox oil, air filters and spark plugs.
Mercedes-Benz ML63 Suspension, Brakes, and Lug Bolts.
Air Suspension: Many ML63s have the AIRMATIC air suspension, which can develop problems as it ages. Look out for sagging, especially comparing the front to back and left to right. Often, it’s worn links on the ride height sensors that cause this. Replacing those links can be a much cheaper fix than replacing the entire air strut.
Brakes: Those high-performance brakes need attention too. Inspect the rotors for grooves and the pads for wear. Replace them as needed, and remember that high-quality brake components are crucial for a vehicle like this.
Lug Bolts: Finally, a quick word about lug bolts. It’s surprisingly common for the security socket to go missing. If yours is missing, consider replacing those security lug bolts with standard ones to avoid headaches down the line. But make sure you keep the code or letter for the security socket and buy a spare, just in case!
Remember, the ML63 is a high-performance vehicle, and that comes with a high-performance price tag. Budget for repairs and maintenance accordingly. By staying proactive and tackling these common issues head-on, you’ll keep your M-Class W164 running smoothly for years to come.
The Importance of ML63 Preventative Maintenance
Preventative maintenance is crucial for extending the life of your ML63 AMG and avoiding costly repairs3. By addressing minor issues early on, you can prevent them from escalating into major problems.
Is it Worth it?
Despite the potential maintenance costs, many owners find the ML63 AMG worth it for its performance, luxury, and overall driving experience2…. As the presenters on the “Brothers On A Budget” YouTube channel explain, the ML63 feels luxurious, powerful, and turns heads.2
