Is timing the only "cold enrichement" system on the PD, or does it inject more fuel too when the engine is cold?
When is the timing returned to that of a hot engine? At which temperature?
The reason for these thoughts is that I monitored the engine temps on my commute to work this week via the hidden meny's in the climatronic display and was surprised of how much longer the engine needs to get up to temp even in moderate cold weather. I wonder if the mileage takes a hit even if it isn't that cold...
At -14C I was up to about 66C efter 12km and it took another 10km to get up to 84C and that's where it parked for a while.
At -6C the engine was at normal operating temp (87) at that 12km mark.
This is with a 550W coolant heater that was on about 1,5hrs before I took off, I think the engine temp was about 30C before I started the car.
Time to put a piece of cardboard in front of the radiator, I usually only do that when it gets really cold.
