Engine
6.2L M156 V8
- Camshaft Adjuster Bolts Failure
- Description/Symptoms: The original camshaft adjuster bolts (also known as camshaft sprocket bolts) are prone to failure. These bolts can shear off, leading to significant engine damage. Symptoms may include a ticking or rattling noise from the engine, especially on cold starts, check engine light, or complete engine failure.
- Solution: Replace the original camshaft adjuster bolts with updated, higher-strength bolts. This often involves removing the valve covers, camshafts, and installing the new bolts to the specified torque.
- Estimated Cost to Fix: $1,500 - $4,000+ (depending on the extent of the damage and if performed at a dealer or independent shop).
- Recalls: None Found
- Valve Lifter/Hydraulic Tappet Noise
- Description/Symptoms: Ticking or clicking noise, especially at idle or low RPMs, indicating worn or failing hydraulic valve lifters. The noise may diminish as the engine warms up, but often returns.
- Solution: Replacement of the faulty valve lifters is necessary. This can be a labor-intensive job, as it requires access to the valve train components.
- Estimated Cost to Fix: $2,000 - $5,000+ (depending on how many lifters need replacement and labor rates).
- Recalls: None Found
- Intake Manifold Failure
- Description/Symptoms: The intake manifold is made from plastic, and it is known to crack which can cause a vacuum leak. This will lead to a rough idle, misfires, and reduced engine performance. The check engine light will likely be illuminated as well.
- Solution: Replacing the intake manifold with an updated plastic or aluminum version.
- Estimated Cost to Fix: $800 - $2,000+
- Recalls: None Found
Transmission
7G-Tronic (722.9)
- Valve Body Issues
- Description/Symptoms: Harsh or erratic shifting, delayed engagement, slipping between gears, or complete loss of gear engagement. These symptoms often stem from worn valve body components, such as solenoids or valve bores.
- Solution: Replacing or rebuilding the valve body is usually the recommended solution. In some cases, individual solenoids can be replaced. Flushing the transmission fluid and replacing the filter is also recommended.
- Estimated Cost to Fix: $800 - $3,000+ (depending on whether the valve body is rebuilt or replaced and whether it’s done at a dealer or independent shop)
- Recalls: None Found
- Conductor Plate Failure
- Description/Symptoms: The conductor plate, which houses the transmission control unit (TCU) and various sensors, is known to fail. Symptoms include transmission going into limp mode (stuck in a single gear), erratic shifting, or a complete loss of transmission function. Diagnostic codes will typically indicate issues with the TCU or sensors.
- Solution: Replacement of the conductor plate and potentially the TCU. Requires programming the new TCU to the vehicle.
- Estimated Cost to Fix: $1,000 - $2,500+
- Recalls: None Found
Suspension
- Air Suspension Issues (Airmatic)
- Description/Symptoms: The E63 AMG is equipped with an Airmatic air suspension system, which can be prone to issues. Common problems include air leaks in the air struts, a failing air compressor, or a faulty valve block. Symptoms include the car sitting unevenly, a noisy air compressor, or the car not raising or lowering properly.
- Solution: Replacement of the faulty air struts, air compressor, or valve block. Diagnosing the exact cause of the problem is crucial.
- Estimated Cost to Fix: $800 - $2,000+ per strut, $500 - $1,500 for the compressor, $300 - $800 for the valve block (parts and labor costs vary widely).
- Recalls: None Found
Electrical
- Electronic Control Unit (ECU) or Module Failures
- Description/Symptoms: Various electronic modules, such as the ECU, SAM (Signal Acquisition Module), or door control modules, can fail. This can lead to a wide range of issues, including engine performance problems, electrical component malfunctions, or communication errors.
- Solution: Diagnosis is critical to identify the faulty module. Replacement and programming of the new module are typically required.
- Estimated Cost to Fix: $500 - $2,000+ per module (depending on the module and complexity of programming).
- Recalls: None Found
- Battery Drain Issues
- Description/Symptoms: The battery drains quickly, especially if the car sits for an extended period. This can be due to a parasitic drain caused by a faulty module or electrical component.
- Solution: Identifying the source of the parasitic drain through a process of elimination, testing individual circuits and components. Repairing or replacing the faulty component.
- Estimated Cost to Fix: $100 - $1,000+ (depending on the source of the drain and the repair needed).
- Recalls: None Found
Exterior
No Issues Found
Interior
- Sunroof Issues
- Description/Symptoms: The sunroof mechanism can fail, causing it to become stuck, noisy, or not operate smoothly.
- Solution: Repair or replacement of the sunroof motor, regulator, or other components.
- Estimated Cost to Fix: $300 - $1,500+
- Recalls: None Found
