M47D20

The original M47 engine was the 1951 cc M47D20. Bowing in 1998, it produced 100 kW (134 hp) and 280 N·m (207 ft·lbf) in its original 320d/520d guise and 85 kW (114 hp) and 265 N·m (195 ft·lbf) in the 318d.

Applications:

  • 85 kW (114 hp) and 265 N·m (195 ft·lbf)
  • 100 kW (134 hp) and 280 N·m (207 ft·lbf)

M47TUD20

BMW 320d models built from approximately September 2001 onwards were fitted with the M47TU (standing for "Technical update"). The exact production week is not known but expect it to be after Production Week 33 of 2001 (eg. you cannot rely on a UK 51 plate registered BMW 320d to have the M47TU).

This updated engine was expanded slightly to 1995 cc, ramping up the torque. It also featured improved consumption and more boost lower down the rev range, however it added 50kg in extra weight and emissions were raised slightly. In the UK, the new engine lifted the 320d into the next highest insurance bracket and next highest band for Vehicle Excise Duty (commonly known as Road Tax).

The M47TU was also fitted with twin balancer shafts to counteract the secondary balances inherent in a diesel 4-cylinder engine. The M47TU was regarded as so good that BMW made it available in the 320Cd Coupé.

Applications:

  • 85 kW (114 hp) and 280 N·m (207 ft·lbf)
  • 110 kW (148 hp) and 330 N·m (243 ft·lbf)


M47TU2D20

The engine was updated again in 2004 as the M47TU2D20. Still at 1995 cc, it produced more power across the range.

Applications:

This engine also experienced turbo problems when at low altitudes such as Cape Town.
