Why I wonder have you bought glowplugs listed for Fiat/ Alfa and not one's listed for P38?
Are you sure they are the correct length and heat value? Not all glow plugs are the same.

Plus the fact that they are not Beru plugs but Quintin Hazel pattern ones. Equivelent to Beru 0100226229. They don't have the reduced tip and don't look right to me.

Well "work" goes from "just work" to "work very well".
Like the assumption I did about the glow plugs either work or don't. I't seems that it isn't always that way. They can be somewhere in between.
BERU, NGK, Delphi or Bosch for the BMW M51 engine.
 
Now, leaving work, only 2 times on the glow plugs and it started right off, without hesitation like the problem never happened.:confused:
Bad fuel? I use the same fuel from the same petrol station for along time now without any problems.
They say at the balcony that it is additivated diesel and cheaper than regular:jaw:.
The company site has a product "datasheet" that explains it is a 7% biodiesel 93% Diesel and some marketing addictive. Strange thing is that every value of the charts between regular diesel and this "special" one, is exactly the same.
I have filled the tank with regular diesel and had about 14 liter = 3.0795682 Imperial gallons.

I had negative "ground" problem. All the crimped terminals were isolated from the cable. I sorted all that out and problems went away. The head can't be isolated from the block can it? All that head bolts...

I'm glad is weekend :eek:

Personally I would not use any odd fuel mix like that unless I made it myself.
A good set of OEM quality glow plugs will set you back about £40.
 
Hi everyone,

The problem seem to be gone again, without any intervention besides a full tank of diesel.
3 cold starts with normal start behaviour.
 
Read this seem to be in conjunction with your problem if you have changed your glow plugs then I would be look here

Well there is two i think they both work in conjunction but the coolent is for cold start and fuel temp whist running in conjunction with water temp :)

ECU coolant temp/fuel temp sensor for cold start. Gauge temp sensor has nothing to do with starting or running just for gauge.

I need to confirm this but I think one coolant temp sensor goes to to ECM and the other goes to Becm.
This is interesting because I built a low coolant/high temperature alarm. I'ts been working as expected, for a year by now. It is a high impedance input device so it should not interfere with the reading.
Anyway, the one that I "tap" for engine coolant temp, is the one that goes to the Becm and the only use that I'm aware of is the dial gauge at the instrument binnacle.

By the way, the Landy has been starting like a charm! No problem.
 
I think one is the ECU, one is for the Temp Gauge on the dash and if you have A/C the thrid is for the HEVAC system....(can't remember if the early models had it on the engine and later on the Heater pipe - or the other way round!)

The A/C on mine, (1996) has a sensor on the heater pipe.
