B 200 M266

The naturally aspirated petrol four in the B-Class, port-injected and chain-driven. It's the low-risk engine in this car, since it has no filter to block and no turbocharger to starve.

Overview

The B 200 is the M266 petrol version of the Mercedes-Benz B-Class MPV (W245), sold 2005–2011 with 136 PS and manual or automatic. Manageable at level 2. The engine has no expensive failure recorded, so the CVT is the only real risk here. 1 failure modes are recorded against its engine, gearbox, chassis and shared components. Prices on this page are illustrative placeholders rather than a sourced market sample. See the methodology for how the bands are derived.

Autotronic CVT shudder and failureMercedes Autotronic CVT€1,200–€2,800

Shudder as the car takes up drive, delayed engagement from a standstill, and in later stages a refusal to move. The belt and the electro-hydraulic control unit both wear, and degraded fluid accelerates each of them. It's a service-dependent gearbox that owners have generally treated as sealed.

Check: Pull away gently several times from cold and feel for shudder or a delay before drive engages. Ask for the fluid and filter record, since that document predicts the largest bill on the car.

Mileage and servicing

What the odometer does and doesn't tell you here, plus the service items whose neglect causes the expensive failures above.

There's no particulate filter and no high-pressure fuel system, so the mileage matters less than how the car has been treated. A manual example with a full book is a genuinely safe buy.

What that meansNo US band exists to compare. Any car you find there's a private import, parts and specialist knowledge are thinner, and the price says more about import cost than about the market.

US figures are the EU band converted at a stated rate. No US market differential is modelled: we hold no sourced US asking prices, and inventing one would be worse than saying so. What the comparison does show for real is availability. Most of this range was never sold in the US.

Buyer notes

Our judgement, kept separate from the records it's built on.

Our read, not a record

The naturally aspirated M266 is chain-driven and port-injected, which removes almost everything that costs money on a modern engine. It's unhurried and that suits the car. Take the manual if you can find one, because it sidesteps the CVT entirely and that's the single biggest risk in this range. So look at the rear axle and the boot floor, and work every electrical function while you're inside.

Everything above this line comes from the issue and specification records. This paragraph is our judgement on top of them. See how we reach it.
