If it starts, think yourself lucky and stop worrying
If you gave it a bit of heater plugs it fired straight away.
The BMW M51 is a straight-6 Diesel indirect injection engine
It should need heater plugs to start. Same as all indirect injection engines of yesteryear
The one I had would always start, hot or cold, if you turned the key....it wound until it started
Direct injection engines also use glow plugs.
Yes....more to control emmisions though...indirect injection diesels need the heater plugs to start
It would be easier to use the heater plugs as they were intended rather than adding hotfix boxes or timing chains. It says in the manual to wait until the glow plug light goes off before starting
All the Di engines of yesteryear were low revving, the problem was to create small high revving Di engines, I think Ford were the first with a sucessful one in the Transit, it had no glowplugs. My current Transit is also Di, it has glow plugs but starts fine without them except in extreme cold.
No, not common rail, uses a mechanical injector pump, the original Tranny Di also used an an old style injector pump, just much higher pressure and a complex inlet manifold designed to cause inlet air swirl.
(in the intake, not into me LOL)

The old Volvo marine Di engines would start in any conditions short of waxed diesel, hand cranking was easier on a rolling boat with a squirt of Easy Start
But its up to him if he wants to believe some internet copy n pasters or the manual that should have come with the car. Think you are missing the point, the glow plug light should not come on when it is hot. The fact that it does means that it probably has the hot start fix fitted. This is fitted to mask an underlying problem, timing out or stretched chains which puts the timing out. He either lives with waiting till the light goes out or does something about it.This thread is not about how diesels work.....though I could go on but I wont.
Its about an indirect injection BMW diesel that you are supposed to wait until the glow plug light goes out on before you start it....as stated in the user manual...the same as almost every other indirect injection diesel.....
To save you checking wammers...as you obviously dont know ...the pcm controls the heater plugs and the light...if it decides it needs to use heater plugs based in input from sensors the pcm switches them and the light on for a predetermined time....the driver waits until the light goes out, then starts the engine. #### all to do with the hotfix mod.
The very diesel that the question is about seems to me to be starting as it should....it says in post 1 that it starts if he waits until the glow plug light goes out it starts straight away. That is the instructions in the user manual.
Me personaly couldnt give a toss if Radar1946 fits hotfix mods or timing chains but I think its a waste of his money
Radar1946...not all internet experts are really experts...a lot of them just like their own typing
What your trying to say the light/glow plugs are probably on? maybe not on, sometimes on.... It starts just fine....just like it always hasWelcome To LandyZone, the Land Rover Forums!
