Glow plugs
Fuel filter
Fuel pump (next to filter)
And new battery

Do you think replace fuel pump in tank will change something ?

Thanks

When you say "zero errors", what are you using to read the DDE errors?

And if you car is LCI (born >09/2003) then the glow plug controller is known to fail more often than the glow plugs.... it's best to change the glow plug AND the glow plugs as a set on LCI cars... saves much work (removing the intake manifold again etc.).

Dunno about your fuel pump, sorry - not enough info. to make a guess.

Does it start OK when the temps are warmer?
