Thread: D1 300tdi a struggle to start in the morning.

Glow plugs are rarely needed on the 300tdi due to direct injection and our warm temp's compared to europe. Only trouble i ever had with mind not starting was on a minus 6 morning in the alps. In that case it was more the diesel i think. I would be more looking at the thermo wax block in the pump. Does it start easier with your foot on the accelerator? Or does the tdi go to max fuel when rpm is below 200rpm. Definately sounds like you need a rave disc still. Stu

Yeah the 300Tdi should start no probs without glow plugs. I'm from Ballarat and mine starts easy with out the plugs at 4am (as they are disconnected from a melted fusible link). Does it turn over slow? If so then, How good is the battery? How's the starter?. Check the earth to chassis connections and battery connections. The starter solenoid switch could be on the way out, they have to pass alot of current and the contacts erode.

Hi
Iwould be checking the earth lead between starter & chassis.
Had same prob with my 200tdi replaced earth & all good.

Yep check all earth and + connections get the battery load tested after all that and no better get the stater motor checked maybe even a strip down of the starter and clean

Check the injector pump timing. This will make them hard to start in the morning when cold, and gutless as anything when cold. The other giveaway is that they are very quiet, and have very little diesel knock.

A quiet Tdi has retarded pump timing
