My D4D (Automatic) has an intermittent shudder coming from the engine or the gearbox, it is hard to determine. It only occurs just before coming to a complete stop, and feels like the engine is shuddering side to side. If I let the vehicle roll while still having minor brake force the shudder intensifies - it will continue if I let go of the brakes completely and let the engine idle while rolling. It feels almost like it is unbalanced, with some shudder making it feel like the engine might implode. The shudder will disappear as I accelerate driving off. I have gathered that it tends to occur when stopping on an up-hill (I think).
Some details on the engine/drivetrain:
- 520,000 km on engine.
- Gearbox fully rebuilt at 490,000.
- EGR blocked.
- Top end of the engine has been machined and rebuilt.
- Snorkel & 4" exhaust.
- Injectors replaced at 450,000.
- Engine mounts have been replaced at 480,000.
- Serviced at every 10,000km.
- Drives on 33" tyres.
Other than that the engine is stock. If anyone has any clues to what it could be that would be great before I take it to the diesel specialist.
