About the Mercedes Benz E Class W212
AI-generatedThe Mercedes-Benz E-Class W212 (2009-2016) represents a significant leap forward from its predecessor, offering a blend of luxury, technology, and refinement that cemented its position as a benchmark executive saloon. Available in saloon and estate (S212) body styles, the W212 introduced sophisticated styling with elegant flowing lines, a more spacious interior, and cutting-edge technology including the revolutionary COMAND infotainment system. Engine options ranged from efficient four-cylinder diesels to powerful V8 petrol variants, with the E63 AMG providing supercar-rivaling performance. This generation featured a comprehensive facelift in 2013 (often referred to as W212.2), which brought revised front and rear styling, improved engines, and enhanced technology including Collision Prevention Assist and more advanced LED lighting. The W212 is renowned for its comfortable ride quality, quiet cabin, and exceptional build quality, though it's not without its issues. Popular UK models include the E220 CDI and E250 CDI diesels, which offer an excellent balance of performance and economy, making them ideal for high-mileage business users and long-distance drivers alike.

- 2015 - Mature production year with most bugs ironed out, updated safety systems, and better reliability than earlier models, plus benefits from manufacturer improvements
- 2016 - Final production year offering the most refined and reliable W212 experience with all updates implemented, though can command premium prices
Worst Years
- 2009 - Earliest model year with biodegradable wiring issues, early OM651 balance shaft problems, and initial production teething troubles that were later resolved
- 2010 - Still affected by balance shaft issues on diesel engines and biodegradable wiring harness problems without the benefit of being a collectible early model

Did You Know?
Did You Know?
The W212 was the first E-Class to feature LED headlights as standard on AMG models and optional on others, creating the distinctive 'eyebrow' daytime running lights.
Mercedes-Benz invested over €1 billion in developing the W212 platform, which also underpinned the CLS-Class (C218).
The E63 AMG Estate became one of the fastest production estate cars in the world, with the S-model reaching 0-60mph in just 3.6 seconds.
Over 2.4 million W212 E-Class vehicles were produced globally during its production run, making it one of Mercedes-Benz's most successful models.
Alternatives to Consider
BMW 5 Series (F10)
More engaging to drive with sharper handling, similar luxury levels, and competitive running costs, though interior quality slightly behind Mercedes
Audi A6 (C7)
Quattro all-wheel drive for better winter performance, excellent build quality, refined diesels, and slightly lower running costs
Jaguar XF (X250)
Stylish British alternative with excellent dynamics, lower purchase prices, but potentially higher depreciation and fewer diesel options
Lexus GS
Superior reliability and lower maintenance costs with hybrid options, though less sporty and smaller dealer network in UK
Volkswagen Passat (B7/B8)
Significantly cheaper to buy and run with similar space and technology, but lacks the prestige and luxury of the E-Class
Owner Tips
- 1Insist on full Mercedes-Benz service history and check for balance shaft replacement on 2009-2014 diesel models - this is critical
- 2Budget £1,000-£2,000 annually for maintenance and repairs; find a reputable independent Mercedes specialist to reduce costs by 40-50%
- 3Check air suspension thoroughly - press each corner and listen for compressor operation; budget for eventual replacement
- 4Ensure DPF has been regularly regenerated on diesel models; motorway runs help prevent blockages
- 5Check for sunroof drain blockages by pouring water into drain channels; clear regularly to prevent interior water damage
- 6Examine rear subframe and suspension mounting points for corrosion, especially on pre-2013 models in coastal or salted areas
- 7Test all electrical functions thoroughly including seat adjustments, climate control, and infotainment - repairs are expensive
- 8Change engine oil and filter annually regardless of mileage for longevity, especially on diesel variants
