The Mercedes-Benz E-Class is now in its ninth generation and sees Mercedes-Benz return to its core qualities of cossetting comfort, safety and high luxury. But most importantly, Mercedes says it signals a return to engineering integrity. After the issues and reliability problems that dogged the previous Mercedes E-Class, especially in the early days, this is an important area for the firm if it wants to regain its reputation for strong build quality and reliability.

First impressions are very favourable and the E-Class certainly feels well built when you get behind the wheel. From the heavy 'thud' of the doors, to the solid feel of the dash and buttons, it's clear this is a far superior car to its predecessor. There's also a welcome return to the more angular interior styling of older Mercedes models, giving a functional and sturdy feel - although it's perhaps not as inviting as other premium cars such as the Jaguar XF.

The bold and sharp exterior styling is certainly a big departure from the previous model, but it retains that disctinctive Mercedes-Benz look. And there are big changes under the bonnet too with new petrol and diesel engines that offer significantly improved fue consumption and better performance too.

On the road the E-Class is everything you'd expect from a Mercedes saloon with a smooth ride, a cossetting cabin and superb refinement. It's not quite as good in corners as a BMW 5 Series, but is still reassuring and composed nonetheless. It's also available with some sophisticated and genuinely useful technology such as a blind spot warning system and adaptive highbeam which automatically dips the headlights if a car is coming in the opposite direction.

Can I fit LED replacement bulbs in my Mercedes E-Class?

"Just wondering if you could give us some guidance on whether LED replacement headlight for a 2012 Mercedes E-Class headlight is a good choice and what would you suggest?"
The MoT inspection manual was updated in January 2021 with the following: 'Existing halogen headlamp units on vehicles first used on or after 1 April 1986 must not be converted to be used with high intensity discharge (HID) or light emitting diode (LED) bulbs. If such a conversion has been done, you must fail the headlamp for light source and lamp not compatible.' We would suggest fitting high-performance halogen bulbs instead, such as Philips RacingVision or Osram NightBreakers as an alternative.

I want a Mercedes E-Class for high mileage - what diesel engine should I choose?

"I'm after a high mileage E-Class Estate (2010-2016). Can you recommend a specific diesel engine that will do 200k as there are a lot to choose from? Also are the diesels chain driven?"
If you want a W212 generation Mercedes-Benz diesel for high mileage, we would suggest choosing one of the six-cylinder OM642 versions found in the E300 and E350 models, as this is more reliable than the four-cylinder OM651 unit. Both of these engines are chain driven.

Should I replace my E-Class diesel with an EV?

"I presently have a Mercedes-Benz E-Class diesel but am thinking of a greener option for the future. However, I am sure I am not alone in seeing "range anxiety" as my biggest worry and am therefore very wary of a pure electric vehicle. Right now I have a vehicle that takes me about 10 minutes to refill at any petrol station and thereby ensures I have a further 350 miles of worry-free motoring. Even though I rarely do much mileage, I can only think that a hybrid will be the only option that will give me the reassurance of not constantly looking at the fuel gauge. Am I wrong?"
Many of the latest electric cars can comfortably cover more than 200 miles from a charge. How often do you cover more than 200 miles without stopping for a half-hour break (during which you could charge the car)? We wouldn't recommend an EV if you're a high mileage driver spending five days a week travelling up and down the motorway, but you might be surprised at how easily an EV fits into your life. If you can charge a car at home and mainly cover short journeys, it'll actually be less hassle than owning a petrol or diesel car as you'll never have to visit a filling station again. If you're not convinced that an EV will work for you, consider a plug-in hybrid as an introduction to electrified motoring.

How much does it cost to replace an oxygen sensor?

"Mercedes have diagnosed a failed oxygen sensor on my diesel E-Class (2010 model) and suggested replacing it would cost around £500. This seems very high to me. What would you consider a sensible price for this work?"
I'd expect to pay £350-£450 at a dealer. However, given the car is 10+ years old, I'd recommend using a local independent Mercedes-Benz specialist (you'll pay £100 less).
