Pull out your injectors and have a look at them.

Only takes 10 mins.

I thought that was 'normal' for a 300TDI? Mine does it too!

Hi Paul

First and foremost, did you check that all the filters and the sedimenter are clear and that the pre-feed pump is working correctly.

If the above is all normal, then the symptoms you describe point towards pump timing rather on the late side. The Bosch Diesel pump needs to advance during cold start. If there is now already a timing error on the late side present, this will amplify the problem.

Take the car to a shop, where they can check the pump timing with a timing light. this is possible with a nifty little device from Snap On, which detects the pulse from the No. 1 injector pipe and converts this into a signal, any normal (high quality) timing light can interprete.

Pump timing should be at 10Deg BTDC.

Good luck

George

Change fuel filter, check lift pump by checking for strong pulse of fuel from filter bleed point when the engine is running.

Also check sedimenter.
