Mercedes-Benz E-Class (W212) — complete buyer's guide
The complete reference for the fourth-generation Mercedes-Benz E-Class (W212/S212, 2009–2016): platform, dimensions, every engine, the 2013 facelift, known issues and a used-buyer checklist.
Production and platform
Produced from early 2009 to 2016. Fourth generation of the E-Class. Available as a four-door sedan (W212) and five-door estate (S212). Long-wheelbase version mainly for China. Rear-wheel drive standard; 4MATIC all-wheel drive available on most versions. Facelift introduced in 2013. Related models include AMG E 63 and E 63 S. Primary assembly in Sindelfingen, Germany. Replaced by the W213 from 2016.
Driving experience
Comfortable, quiet and built for long distances. The W212 rides with a soft, absorbent gait, especially on AIRMATIC, steers lightly with little feedback, and cruises with the calm composure of a large executive saloon. Rear-drive is standard and gives a classic balance; 4MATIC adds traction. The OM651 diesel is the sensible distance choice and stays quiet, the M276 V6 petrol is smooth and strong, and the 7G-Tronic shifts unobtrusively. It is a genuinely comfortable, dependable executive car that does motorway miles with little effort.

Transmissions
5G-Tronic or 7G-Tronic automatic (later 9G-Tronic on some facelift diesels); 6-speed manual available on some early four-cylinder models. All engines longitudinal. Euro 5 / Euro 6 compliance depending on year and engine.
Dimensions and practicality
Sedan length approximately 4,868–4,879 mm. Width around 1,854 mm. Height around 1,471 mm. Wheelbase 2,874 mm. Boot volume approximately 540 litres (sedan). Estate (S212) boot approximately 695 litres (seats up), expanding to roughly 1,950 litres with seats folded. Fuel tank capacity typically 59–80 litres. Compared with the previous W211: improved refinement, safety features, and interior quality. Practicality is strong for an executive sedan/estate of the period, with the estate offering excellent load volume.
Facelift (2013)
Introduced in 2013. Main changes: revised exterior styling (grille, lighting, bumpers); updated interior and COMAND infotainment; engine refinements and efficiency updates; introduction of 9G-Tronic on some diesel models; equipment and safety improvements.
Differences from the previous generation (W211)
Improved refinement, safety systems, and interior quality. Updated engine options (OM651 diesel, M274 petrol). Better ride characteristics. Overall more modern packaging than the W211 while retaining similar practicality.
Known issues and weak points
Air suspension (AIRMATIC, where fitted)
- Leaking air springs (especially rear) and compressor failures common at higher mileage. Corner sagging after overnight parking is a typical symptom. High repair costs.
Diesel (OM651 / OM642)
- OM651: timing chain stretch and tensioner issues on pre-facelift examples (cold-start rattle). Injector faults more common on early cars.
- OM642: oil cooler gasket leaks (oil/coolant mix in the V), swirl flap issues, NOx sensor and AdBlue faults. DPF clogging more common on short-trip use.
- EGR issues possible on both.
Petrol (M271 / M272 / M276 / M278 / M157 / M156)
- M271: timing chain and guide wear on some examples (cold-start rattle).
- M272 / M276: intake manifold issues possible, carbon buildup on direct-injection versions, oil leaks.
- M278 / M157 (V8): cylinder scoring risks on some units, timing chain issues, higher maintenance demands.
- M156 (early AMG): head bolt and cam wear risks on specific production periods.
- Electronic steering lock (ESL) failures reported.
Transmission (7G-Tronic)
- Conductor plate or valve body issues possible at higher mileage. Fluid service recommended earlier than official intervals. Generally durable with maintenance.
Other
- Electronic parking brake actuator failures.
- Suspension bush and control arm wear (clunks) at higher mileage.
- Multiple recalls (timing chain, airbags, software, fuel system). Always verify full VIN status.
- Interior wear and rattles on higher-mileage examples.
What a buyer should check
- Full service history, including air suspension operation (if fitted) and transmission fluid changes.
- VIN-specific recall and service campaign status (timing chain, airbags, emissions software).
- Air suspension function: all corners level after overnight parking, no sagging.
- Cold-start engine noise (timing chain rattle on diesels or early petrols).
- Oil leaks, cooling system condition, and any coolant/oil mixing on V6 engines.
- For diesels: AdBlue system function, DPF regeneration history, and NOx sensor faults.
- Transmission behaviour from cold and in traffic.
- Electronic parking brake operation and suspension condition.
- Full electronic function and signs of interior wear.
Running costs
Indicative costs for the Mercedes-Benz E-Class W212 in normal Belgian/EU use (approximate 2026 figures). Actual figures vary by region, driving style and service location.
Fuel consumption
- E 200 / 250 (M271/M274): typically 6.5–9.0 L/100 km.
- E 350 (M276 V6): typically 9.0–11.5 L/100 km.
- E 500 (M278 V8): typically 11.0–14.0+ L/100 km.
- E 200 CDI / 220 CDI / 250 CDI (OM651): typically 5.0–6.5 L/100 km; AdBlue consumption low.
- E 350 CDI (OM642): typically 6.5–8.0 L/100 km.
Maintenance
Mercedes service is premium-priced. Oil service typically €200–400. 7G-Tronic automatic fluid service every ~60,000 km is recommended. Tyres and brakes add up. AdBlue consumption on the diesel is low. AIRMATIC air suspension can be expensive to repair. Independent Mercedes specialists keep bills more reasonable than dealers.
Road tax / registration (Belgium)
Highly region-dependent (Flanders more CO₂-oriented; Wallonia/Brussels influenced by power/CV and mass). The four-cylinders sit in moderate brackets; V6/V8 higher. Expect roughly €300–1,500+/year depending on engine, exact CO₂, region and any ongoing reforms. One-off BIV/TMC on first Belgian registration is also engine- and age-sensitive.
Insurance and LEZ
Premium business saloon; V8 variants rate higher. Annual premium heavily dependent on age, history, location and cover level. Full comprehensive is expensive on higher-value examples. LEZ: all engines Euro 5/6 compliant and admitted in Belgian/EU low-emission zones.
Belgian/EU market notes
The E-Class W212 remains a well-represented executive car in the Belgian used market, competing with the BMW 5 Series and Audi A6 of the same period. The E 220 CDI / E 250 CDI diesels were frequent choices for mixed private and company use due to torque and fuel economy. Estate versions (S212) appeal to buyers needing higher load volume and practicality. Road tax and registration tax are significant due to weight and power; regional differences apply. Car-Pass documentation is required for Belgian sales. Many examples show higher mileage from mixed use. Facelift cars (2013–2016) generally benefit from refined engines and updated electronics. Early production requires closer scrutiny of specific OM651 timing chain campaigns and air suspension condition. The sedan is more common than the estate in the used market.
Summary
This generation offers solid refinement and practicality for an executive sedan/estate of its era, provided the known cost items (AIRMATIC air suspension where fitted, diesel AdBlue/DPF and oil cooler issues on OM642, petrol timing chain risks on early engines, and full VIN recall status) are verified. Cars with steel springs avoid the highest air suspension repair risks. Facelift examples are generally more stable. The OM651 diesel with full service history remains a common and practical used choice.
