Considering a pre-owned 2007 Mercedes-Benz E 550? It’s a vehicle known for its robust performance and luxury features. However, like any car, especially one with mileage, understanding potential maintenance needs is crucial. While the 2007 E 550 model year is past the earlier timing chain concerns, there are specific areas owners and prospective buyers should be aware of.
Airmatic Suspension: A Point to Inspect on the 2007 E 550
One of the most frequently discussed topics regarding the E-Class, particularly models like the 2007 Mercedes Benz E 550, is the Airmatic suspension system. By this age, if the original Airmatic components haven’t been addressed, they are likely nearing or past their expected lifespan. Replacement costs at dealerships can be significant, often around $1000 per corner. Fortunately, aftermarket options like Arnott offer more budget-friendly alternatives, typically in the $500 range or less per corner. Unlike the E350, the E 550 often comes equipped with Airmatic, making it a key inspection point.
Intake Manifold Issues in the M273 Engine of the 2007 E 550
The 2007 Mercedes Benz E 550 is powered by the M273 engine, and a common issue to anticipate is the intake manifold. While it might not be immediately apparent, the oil separator/breather cover can degrade over time, leading to oil accumulation in the intake manifold. This oil buildup can gum up the intake flaps, making the lever in front of the intake increasingly stiff. If left unaddressed, these flaps can break and potentially cause serious engine damage. Proactive replacement of the oil separator/breather cover might offer some preventative measure and extend the intake manifold’s life. However, eventual intake manifold replacement should be considered part of the long-term maintenance plan for a 2007 E 550.
High Mileage Components and General Wear on a 2007 Mercedes E 550
With mileage often reaching 150,000 miles or more on a 2007 Mercedes Benz E 550, general wear and tear is inevitable. A pre-purchase inspection is paramount, as the condition can vary greatly depending on prior maintenance. Common wear items at this mileage include ball joints, tie rods, control arms, bushings, sway bar links, motor mounts, flex discs, and brakes. Engine-related components such as tensioners, pulleys, belts, oil cooler/coolant gaskets, and rear oil plugs also warrant inspection. Consistent maintenance can mitigate many of these issues, but thorough evaluation is essential to assess the current state of these components.
P2 Package Features: Keyless Go and Other Electronics in a 2007 E 550
Many 2007 Mercedes Benz E 550 models are equipped with the Premium 2 Package (P2), which includes desirable features like bixenon headlights and Keyless Go. While these are attractive amenities, potential issues can arise with age. Keyless Go door handles, in particular, are known to fail, especially in climates with moisture, due to corrosion of the internal switches. It’s advisable to test all door handles for locking and unlocking functionality. Replacement handles can be costly, ranging from $200 to $300 each, but using the key fob remains a viable alternative. Also part of the P2 package is Parktronic, a parking assist system, which should also be checked for proper operation. Ensure you receive two key fobs with the vehicle, as Keyless Go fobs are more expensive to replace than standard keys.
Conclusion: Due Diligence for 2007 Mercedes-Benz E 550 Ownership
In conclusion, a 2007 Mercedes-Benz E 550 can be a rewarding vehicle to own, offering a blend of performance and luxury. However, understanding the common maintenance points, particularly concerning the Airmatic suspension, intake manifold, and general high-mileage wear, is essential for prospective buyers. A comprehensive pre-purchase inspection by a qualified Mercedes-Benz technician is highly recommended to ensure informed ownership and to anticipate potential maintenance needs. By addressing these points, you can better navigate the ownership experience of a 2007 E 550.
