BMW 330d E46 Facelift M57D30 (306D2) 3.0 Diesel Engine for Sale — South Africa

In 2002 BMW updated its M57 six-cylinder diesel, lengthening the stroke to 90 mm for 2,993 cc and reworking the injection and turbo system. This technical update, listed here under the internal code 306D2, was the engine that went into the facelifted E46 330d and a range of larger BMWs, and it is the reason the later 330d felt noticeably stronger than the original.

This unit is offered as a base engine without a turbocharger. That suits workshops and owners whose existing turbo is healthy, or who prefer to fit a new or reconditioned turbo of their choice. It also makes the price easier to manage on an older car.

When building this engine into a car, fit a turbo that matches your vehicle's original specification, prime the turbo oil feed before first start, and make sure the intercooler and pipes are clean. Check the swirl flaps in the intake, injector seals and glow plugs, and replace the cooling system plastics if they are original.

In South Africa the facelift E46 330d is a sought-after car for drivers who want torque and economy in a compact BMW. Workshops like the M57 because it is well proven and service procedures are widely known. Send your VIN and block code so we can confirm fitment.
