The Mercedes-Benz E-Class BlueTEC models, spanning from 2007 to 2017, represent a significant chapter in diesel passenger cars, particularly in Colorado. This era saw the introduction of the OM642 and OM651 engines, known for their impressive fuel efficiency. As the Dieselgate buyback program prompted many owners to sell, the remaining E-Class BlueTEC vehicles have become increasingly valuable, especially among loyal diesel enthusiasts. These models remain popular for long-distance commuting, offering more than 40 MPG and a spacious, comfortable ride.
As time passes, the E-Class BlueTEC is evolving from a reliable commuter vehicle into a sought-after collector's car. With the Dieselgate buybacks leading to a decline in available units, those that remain in the fleet not only provide excellent MPG but also possess a unique automotive history. Donating your E-Class BlueTEC can support a worthy cause while allowing you to pass on the legacy of diesel innovation to another driver.
📖Generation guide
W211 • 2007-2009
The E320 BlueTEC features the OM642 V6 3.0L engine, known for its torque and durability but susceptible to oil cooler and swirl-flap failures, making it a favorite among diesel enthusiasts.
W212 • 2010-2016
This generation introduced the E350 and E250 BlueTEC with the OM651 engine, offering a lighter 4-cylinder diesel option. It’s celebrated for its fuel efficiency but can face timing chain and SCR issues.
W213 • 2017
The brief production of the E300d marks a significant point, showcasing a final nod to diesel technology before the market shift, though its rarity limits comprehensive exposure.
Known issues by generation
The E-Class BlueTEC models have specific issues that donors should be aware of. The W211 generation is often plagued by oil cooler failures and swirl-flap motor issues, which can lead to costly repairs if not addressed. The W212 models face challenges with timing chain stretch, particularly between 100,000 and 150,000 miles, and the AdBlue SCR systems in later years can suffer from failures that require significant maintenance. Additionally, DPF regeneration issues are common for drivers making short trips. Owners should also be aware of potential transmission valve-body problems in the 7G-Tronic+ system and the occasional electrical issues with the COMAND head-unit or Airmatic suspension on equipped variants.
Donation value by condition + generation
Donation values for E-Class BlueTEC models typically range from $2,500 to $6,000, highly influenced by mileage and condition. Low-mileage examples, especially those with the AMG-line sport package, can command values above $5,000, which may require a Form 8283 for appraisal. While there was no surviving manual-transmission variant in the U.S., the impact of the Dieselgate buyback program has led to a reduced donor pool. Donors should also consider the condition of the AdBlue system; well-maintained cars can fetch higher values at donation.
Donation process for this model
When donating your E-Class BlueTEC, it's important to verify paperwork, especially if your car was part of the Dieselgate buyback program. Ensure the AdBlue tank is near-empty and disclose the DPF regeneration cycle status, as these details can affect the vehicle's valuation. Understanding your car’s emissions certification is also crucial; be aware of whether your vehicle qualifies under 50-state or 49-state emissions regulations, especially if it has been registered in a smog state.
Colorado regional notes
In Colorado, diesel loyalists appreciate the efficiency and longevity of vehicles like the E-Class BlueTEC, making them ideal for long-distance commutes on the state’s expansive highways. However, the salt-belt rust issues from the 1990s and 2000s can affect older vehicles. Additionally, the debate over biodiesel availability and legality adds another layer for diesel enthusiasts to consider. Those commuting to smog cert states, such as California or New York, should be aware of CARB compliance when donating their vehicle.
