Reliability & watch-outs
Known issues
- OM651 diesel: timing chain and AdBlue/NOx issues possible
- 7G-DCT: judder or delayed engagement if fluid is neglected
- Early M270 petrol: timing chain risk reported
- Electric B 250 e: battery degradation and limited range
- OM654 diesel: AdBlue / NOx sensor faults and DPF clogging more common on short trips
- 7G-DCT/8G-DCT needs earlier-than-official fluid changes
- Early M282 (1.3): elevated oil consumption reported
- 4MATIC differential can show noise/wear at high mileage
Pros
- 488 L boot growing to ~1,547 L — roomier than a C-segment hatchback
- Proven M270 1.6/2.0 petrol and OM651 2.1 diesel (B 200 CDI: 136 hp / 300 Nm)
- High seating position with optional 4MATIC all-wheel drive
- B 250 e Electric Drive: 179 hp electric motor with 340 Nm for emission-free driving
- High seating position with a 455 L boot growing to ~1,540 L — roomier than a C-segment hatchback
- Efficient OM654 2.0 diesel (B 200 d: 150 hp / 320 Nm, ~4.2 L/100 km)
- MFA2 platform shared with the A-Class W177, with MBUX dual-screen and optional 4MATIC
- B 250 e plug-in hybrid: 218 hp system output and 450 Nm, company-car friendly
Cons
- OM651 diesel: timing chain and AdBlue/DPF need checking at high mileage
- 7G-DCT needs earlier-than-official fluid changes
- COMAND infotainment (no MBUX) feels dated next to the W247
- OM654 diesel: AdBlue / NOx sensor faults and DPF clogging more common on short trips
- 7G-DCT/8G-DCT needs earlier-than-official fluid changes
- Early M282 (1.3): elevated oil consumption reported

Driving experience
Mercedes-Benz B-Class
High-seated, practical and easy to live with. The W246 rides comfortably enough, steers lightly and accurately, and gives an elevated view that makes town driving and loading children straightforward. The M270 petrols are willing but coarse, the OM651 diesel is the economical choice for distance, and the B 250 e is smooth and silent if its range suits you. The 7-speed dual-clutch is smooth once moving, though hesitant from a standstill. It is a sensible family car, but its refinement and cabin tech lag well behind the W247.
Mercedes-Benz B-Class
Comfortable, quiet and far more modern than the W246. The W247 rides with better isolation, steers lightly and accurately, and keeps its high seating position without the body roll of the old car. The M282/M260 petrols are smooth and eager, the OM654 diesel is the long-distance pick, and the 250 e plug-in covers short trips on electric power. The dual-clutch is smoother than before. It is a more grown-up, better-built family car than the W246, with MBUX tech and a cabin that finally feels like a proper Mercedes.
