Hi,
I have this problem only when starting the engine, hard to start and huge smoke of unburned diesel, the engine limps.
After few seconds, no problem, it turns almost fine.
When warm, the engine runs very well, no white or black smoke.
Relay and heating plugs are new.
When I started this abandonned car, I noticed red wire for solenoïd from ECU has'nt power.
I was obliged to connect to another plus.
Could it be wise to replace the ECU ?
Caus' I suspect the heating plugs cut off to early.

Hi, bit late response.
Did you look at the low pressure fuel system? So the supply to the diesel pump? Even a small leak will cause air to enter this system and then when you start it after it sat for some hours it gets air bubbles instead of Diesel. Very common. I've had it happen on a Fiat TD and on a 156 JTD. On the Fiat is was a porous return line that had no visible diesel leakage. The 156 had a loose watertap screw on the diesel filter that did show some diesel leakage.

Re: td smoking
Okay I will have a look at these, it's plausible causes. Many thanks.Engine wrote:Hi, bit late response.

P.S: I have lots of regrets about my TS, it was a very good car.
