The Mercedes E-Class is a mid-size executive saloon and estate — one of the best-selling large premium cars in the UK. The W212 (2009–2016), W213 (2016–2023) and W214 (2024–present) are all common on UK roads. Available as saloon, estate, coupe and cabriolet. Particularly popular with high-mileage business drivers, taxi operators and families wanting a large premium estate. The E-Class estate is considered one of the finest practical premium cars ever made. AMG variants and PHEV models are increasingly common as fleet returns arrive on the used market.

7 Most Common Mercedes E-Class Problems
These are the faults most frequently seen on the Mercedes E-Class by UK garages — ranked by how commonly they occur and what they cost to fix.
The W212 E-Class with the 2.1 CDI diesel shares the same critical balance shaft and oil pump failure as the W204 C-Class. Cold-start rattle is the warning sign. One of the most expensive and common failures on used W212 Mercedes diesels.
💷 Typical repair cost: £2,000–£7,000
E-Class CDI models — particularly estate examples used as school run vehicles — develop DPF blockages very regularly.
💷 Typical repair cost: £150–£1,800
The 7G-Tronic and 9G-Tronic automatic gearboxes can develop judder, harsh shifts and complete valve body failures when oil change intervals are neglected.
💷 Typical repair cost: £500–£4,000
W213 and W214 CDI models require AdBlue. Sensor faults and running dry cause warnings and prevent restarting.
💷 Typical repair cost: £10–£900
The AIRMATIC air suspension — very common on E-Class — develops compressor, strut and valve block faults on higher mileage examples.
💷 Typical repair cost: £500–£2,500
The PHEV battery in E300e and E300de models degrades over time. Always verify real-world EV range before buying.
💷 Typical repair cost: £2,000–£6,000

💷 Typical repair cost: £400–£1,200

Mercedes E-Class — MOT Tips
The W212 2.1 CDI balance shaft issue is the most expensive check — listen for cold-start rattle. DPF and AdBlue warnings are MOT fails or MOT-relevant. AIRMATIC suspension must hold correct ride height. All gearbox warning lights must be clear. PHEV high-voltage warnings must be clear on E300e/de models.
Engine management light on before your MOT? It's an automatic fail. Run a
MotorLoom diagnostic for £1.99 to get the likely cause and repair cost before booking the test.
Mercedes E-Class Tyres
Most Mercedes E-Class models run 225/55 R17 or 245/45 R18 or 245/40 R19 or 255/35 R20 depending on trim level and year. Always check the placard inside the driver's door for the exact size for your vehicle.
Summary
The E-Class is an exceptional used buy — particularly the W213 estate which offers outstanding quality and space at competitive prices. Avoid early W212 2.1 CDI diesel unless the balance shaft risk has been investigated. The W213 E220d with proven service history is a brilliant used choice. AIRMATIC service history is the second key check.
