Thread: Warming up TDI engine?

just long enough to get the oil pressure up and the idle stable then if its cold enough for it to need that (assuming the engine is in good tune) gently for the first few hundred meters to get the oil moving round the drive line and then into it.

As said already, no warm up/idling, just start up drive off. I putt putt along very easily until there is a little temp up.
Taking off with cold engine on flat ground you don't need over 7-8psi boost or 1500rpm to get moving, that is pretty gentle and easy on engine.

i dont give mine a hard time until the temp and pressure is up abit, but i dont sit there and wait for it to idle...

All engines are the same - they SHOULD NOT be "warmed up" in the old-fashioned manner of leaving them idling.

Start.
Wait ~30-60s for oil to get to top of motor.
Drive gently till at operating temp.
Drive how you want after that (regular hard driving is good for keeping carbon deposits and glazing at bay).

Best thing you can do for your motor is to never start it.

By idle-ing a diesel, you are potentially doing more harm with glazing bores etc.
Warm motor on glow plugs and start once the light is out.
Put in gear and take it easy till metal has warmed up a bit and fluids are warm.
Bit like you jumping out of bed and straight into it.

Diesel like to work, when they are at optimum operating temperature, they like being under load and let the compression do the work.

Diesel taxi's which are used the world over except for here in OZ do 1 million km's no problem.
There is a mercedes Taxi from the greek islands in the mercedes museum that has 4 million km's on it.
Sure it had head off and some work done but the guy drove it there and Mercedes gave him a brand new Car in exchange.

The hot and cold and expansion and contraction of metals of varying hardness is what gets them in the end.

Umm - you might want to check on that. The guy had 3 or 4 engines which he used to swap on a regular basis (every couple of hundred thousand... So 4 million km on the chassis, ~1 mil km on each engine but with an unknown number of rebuilds.

Only a million k's on the engine ? That's **** ! LOL

I bet that taxi driver had a brother-in-law in Melbourne.
