From 3 forum threads and 2 press tests · updated 12/10/2026

What the reviews say

• The B-Class stands out for its roomy, versatile cabin, generous rear space, large boot and easy access through wide-opening doors.[5]one sourceW245W246
• Road manners are stable and balanced, with good grip and little understeer at normal speeds; the diesel is also credited with good motorway refinement.[5][4]W245W246
• An owner of a 2008 2.0-litre petrol automatic described it as compact, comfortable and stable, but also low and rather firm.[1]one sourceW245
• The B200 CDI is praised for economy and practicality: the source cites roughly 4.5–5 L/100 km combined, ample cabin height and a generous boot.[4]one sourceW245W246

Typical faults

• Short urban trips can clog the B200 CDI's DPF, causing a warning light and power loss because the filter does not reach regeneration temperature.[4]one sourceW245W246

  B200 CDI

• Soot can accumulate in the B200 CDI's EGR valve; sticking may cause rough starting, unstable idle and loss of power.[4]one sourceW245W246

  B200 CDI

• The source reports premature water-pump failure on the W245 B200 CDI with OM651 at 100,000–150,000 km, risking coolant loss and overheating.[4]one sourceW245

  100 000–150 000 km · 2007–2011 · B200 CDI OM651

• The W245 CVT may judder and respond slowly or abruptly after 100,000 km; the source warns that mechanical repair can be costly.[4]one sourceW245

  100 000+ km · CVT automatic

• W245 CV-joint boots are described as a recurring weak point: they split, and even original replacements may fail again after a few years.[3]one sourceW245
• An owner of a 2005 diesel reported failures of interior door handles and locks, the sunroof blind, rear wiper and bonnet latch.[1]one sourceW245

Which engine and version to take

• The B200 CDI suits regular longer journeys, combining adequate performance with roughly 4.5–5 L/100 km, provided the DPF gets opportunities to regenerate.[4]one sourceW245W246

What to avoid

• Avoid the B200 CDI for almost exclusively short urban trips, as this use promotes DPF blockage and soot accumulation in the EGR system.[4]one sourceW245W246

What to check at the inspection

• Start the engine fully cold: it should settle quickly into a smooth idle; a metallic cold-start noise may indicate a stretched timing chain.[5][4]W245W246
• On the test drive, ensure the engine pulls cleanly uphill and under load, without power loss, hesitation, juddering or black smoke.[5][4]W245W246
• On a B200 CDI, scan the DPF and EGR systems with Mercedes-compatible diagnostics; beware of a DPF warning, rough idle and power loss.[4]one sourceW245W246
• Check the automatic transmission at low and medium speeds; juddering or slow and abrupt responses may signal transmission trouble.[4]one sourceW245W246
• On a W245, inspect the underside, rear area around the spare wheel and suspension, and lower door edges; the forum source advises rejecting cars showing rust.[2]one sourceW245
• Test all electrical equipment, door handles and locks, the sunroof blind, rear wiper and bonnet latch.[5][1]W245
• Demand a service history and evidence of regular oil changes; inspect bumper corners, wheels and doors for damage or poor previous repairs.[5]one sourceW245W246
