300 Tdi Idle Speed Variation

Recommended Posts

Now the following symptoms I beleive are not unheard of on a 300 Tdi but after trawling this forum and the web for quite some time and speaking to some diesel specialists I am still none the wiser as to why.

My disco starts, runs, drives and pulls well with no real concerns, however there is quite a considerable variation between hot and cold idle speeds. To this extent I have to set the throttle stop screw accurately so the idle is not too high when warm but at the same time enough to allow the engine to run smoothly on cold startup.

The differences betweem cold a warm rpm is about 200. So my cold rpm is 700 and warm 900.

After reading up on the bosch manual for the VE pumps I am familiar with their method of operation but without further experience and even talking to a bosch specialist I (we) cannot identify where the symptoms may be emanating from.

So chaps, anyone else come across this before before I have to schedule pulling the pump off and getting it checked over on a test bench for muchos beer tokens?
