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 :) 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. :)

Radar1946...not all internet experts are really experts...a lot of them just like their own typing :)

Old ones used to start by banging loads of fuel in, hence the clouds of smoke that surrounded them on frosty mornings. Can't do that anymore it ain't allowed. Used to saw the top off old pistons, put two or three of grooves in the squish band and polish them to make ash trays.

Hi, The engine starts first time when cold, but every time after even when hot I have to wait for the glow plug light to go off, and it starts straight away. Any ideas or do the rr bmw engine always do this?.

They don't unless the hot fix is fitted. What part of that is difficult to understand?

very good if thats what you think thats fine.

"The fact that it does means that it probably has the hot start fix fitted"

whats the probably for? it either does or it doesn't :) What your trying to say the light/glow plugs are probably on? maybe not on, sometimes on....

but we'll go with that...the glow light is on and theres no hotfix fitted...so what now?

I'll point out now that I have a P38 2.5 diesel that does NOT have a hotfix mod :) It starts just fine....just like it always has

Your last remark means that you are lucky. I said probably because his car is not in front of me to look if there is a hot start fix fitted, my balls are hairy not crystal. I was just going on the information given and the usual reason for the heater plug light to be on when it's hot is that it has had a h/s fix fitted.:)

Think this bloke is a bit of a smart arse Alan. Thinks he knows a bit. We will see how much he knows as time goes by. On his profile he has not made any friends yet, which i do not find to be a very big shock to be honest. :);)

For avoidance of doubt, the glow plug light/glowplugs do not come on when the engine is hot on the M51 unless the mod is fitted.

Oh yes, the old Tranny used to lay down a real smoke screen on cold starts:eek: No smoke on the Tddi though.:)
 
Hi Sorry I have caused a load of trouble, I don't like to ask again lol. I thank you all for your views and you have helped me a great deal. I hope to return the favour some day. I have removed the EGR and it runs a lot better.
