Mercedes-Benz

The most common Mercedes diesel of the last decade (C, E, Sprinter, Vito). Known for Delphi injection issues, timing chain wear, and VGT turbo problems.

Petrol unit of C and E Class. Famous for timing chain stretch and camshaft adjuster wear, hence frequent timing correlation codes.

V6 diesel from ML, GL, E Class and Sprinter. EGR and swirl flaps clog up, and the oil cooler seals famously leak.
