For enthusiasts deeply rooted in the legacy of the Mercedes-Benz W123 and W124, the W210 generation initially sparked skepticism. However, as experience unfolds, many have been won over by the W210, particularly models like the Mercedes E320. This shift in perception is well-earned, as the W210 E320, with its robust engineering and ease of maintenance, proves to be a surprisingly dependable vehicle.
While the driving experience differs from its W124 predecessors, the Mercedes E320 W210 boasts its own set of strengths. Like any car, it has quirks, but addressing these common issues paves the way for remarkable reliability. At the heart of the E320 lies the M112 engine, renowned for its bulletproof internal components. Anecdotal evidence from seasoned Mercedes-Benz mechanics highlights the engine’s durability, with claims of never needing to remove the cylinder heads on an M112. Common maintenance points include valve cover breathers, which are easily addressed when leaks occur, and spark plugs, impressively durable for up to 100,000 miles.
The 722.6 transmission, a key component in the Mercedes E320, also has a strong track record. While early models had a bushing issue, later “facelift” versions incorporated improvements. Regular fluid changes are crucial for longevity, and potential issues are often limited to the electrical connector/bushing or the conductor plate – relatively minor fixes. Opting for a facelift W210 Mercedes E320 is often recommended for the transmission upgrades and other enhancements included in these later models.
For Mercedes E320 owners, preventative maintenance is key to ensuring lasting performance. Beyond the standard new-old car checklist of belts, hoses, and fluids, replacing the crank position sensor is a wise, inexpensive precaution. Be prepared for potential window regulator failures, a common issue in this generation. For those who drive long distances in their Mercedes E320, proactive measures like replacing the transmission conductor plate and electrical plug during fluid changes can provide extra peace of mind. Carrying a spare MAF sensor and K40 relay on road trips is also a practical step for dedicated owners. Finally, maintaining well-packed front wheel bearings is advisable, as they may be slightly more susceptible to wear compared to earlier Mercedes-Benz chassis.
In conclusion, the Mercedes-Benz E320 W210, while initially met with skepticism, stands as a testament to robust German engineering. By understanding and addressing its common idiosyncrasies, owners can unlock the inherent reliability of this model, particularly appreciating the durability of the M112 engine and the 722.6 transmission. With sensible maintenance and a proactive approach, the W210 E320 proves to be a dependable and rewarding choice for Mercedes-Benz enthusiasts.
