Cold start (advance ?) on HDi - Dzl

Hi,

Cold weather seems to have a significant effect on my HDi. It drinks diesel and there is a lot of head noise (crackle, esp. under load).

I remember my old XUD had a system of cables & levers to advance injection timing when cold, and this certainly made it sound like a bucket of nails being shaken.

Presumably the ECU on the HDi is doing something similar?

Why advance timing when cold?

What other tricks does the ECU get up to?

Ta.

You advance timing on a diesel to assist cold start.

I posted about this exact same thing not so long back - the general consenus was that it was OK, and that winter diesel doesn't help.
