Likely spend is the mid cost of every issue rated common or universal, added together, what an unmaintained example owes over the next few years, not a prediction for any one car. Worst case if everything here failed at once is €2,800, which isn't a realistic scenario but is a useful ceiling.

All issues, by system

Transmission

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.

How to read this

Every issue is authored once against the part that actually carries it: the engine, the gearbox, the chassis or a shared component, and inherited by every variant that has that part. The badge next to each issue says where it comes from, so you can tell an M266 problem from an E9x problem.

Evidence tiers. Manufacturer means a recall, technical bulletin or revised part number. Documented means workshop data or multiple independent sources. Reported means owner consensus with no hard confirmation, and never sets a risk level on its own.
