E63 AMG 5.5L Biturbo V8
Petrol
Listen closely while at a standstill and during slow maneuvers for any clicking or clunking sounds from the front end. | Description: It is worth noting that the W212 E63 uses air suspension, and on examples of this age, it is quite common for the air struts to eventually show signs of wear or leakage.
Check this by accelerating firmly on an empty, safe road while monitoring the dash for any engine management lights. | Description: The M157 5.5L Biturbo engine is a powerhouse, but it is sensible to look for any signs of hesitation or misfiring that might suggest the ignition coils or injectors are due for a service.
During the test drive, shift the transmission manually through all gears to ensure the changes are smooth and predictable. | Description: The MCT (Multi-Clutch Transmission) is a unique piece of engineering, and it is helpful to verify that it transitions between modes without excessive jerkiness or delay.
Examine the service history specifically for records of coolant or oil leaks near the turbocharger oil lines. | Description: Due to the extreme heat generated by these biturbo setups, it is a prudent practice to keep an eye on the seals around the engine bay as the vehicle matures.
Consider a full transmission fluid and filter flush to keep the MCT gearbox shifting optimally.
Monitor the engine mounts, as the high torque of the V8 can occasionally lead to them softening over time.
A good point to inspect the secondary air injection system and confirm the integrity of vacuum lines around the engine.
Prioritize a pre-purchase inspection from an independent specialist familiar with high-performance Mercedes-Benz platforms.
Ensure you have a record of regular oil changes using high-quality synthetic oil, as the biturbo engine benefits greatly from clean lubrication.
Check the condition of the brake rotors and pads, as they are substantial performance items that require specific care.
Verify the age and condition of the tyres to ensure you have the best grip possible for that V8 power.
Confirm that the COMAND infotainment system and all electronic driver aids are functioning as expected during your initial inspection.
Estimated repair costs if issues arise
Because these systems involve complex air bladders and sensors, it is wise to keep a buffer in your account just in case one of the corners starts dropping overnight as the car reaches higher mileage.
Regular maintenance is the key to longevity here. Depending on how the car has been driven, you might eventually need to budget for a thorough service of the transmission solenoids and fluid.
The E63 stopping power is exceptional, but the large discs and performance pads are wear items. It is helpful to plan for these ahead of your WOF or annual service.
