- Chain drive at the side of the engine emitting the forces
- Single-part chain drive for driving the camshafts
- Single sleeve-type chain 8 mm
- Electric motor of the combined oil-vacuum pump via a separate chain
- Plastic tensioning and guide rail
- Hydraulic chain tensioner with spring preload and sealing sleeve.

The main difference between the chain drive compared with the B58 engine is
the move from a two-
part timing chain drive to a single-part timing chain drive. Deflection via the
intermediate shaft on the
top timing chain and the second timing chain is no longer needed. The chains
used here are 8 mm
sleeve-type chains. Because the intermediate gearing is no longer needed, the
number of teeth on the
crankshaft (23 teeth) and the VANOS adjuster (46 teeth each) has also changed.
