Hello guys.
I have a “minor” problem going on with my car. Last couple of weeks since it became cold in the morning my glow plug light started flashing after i get in my car and start driving to work. It starts flashing after about 1km of driving, car goes into limp mode and a start-stop system unavailable message pops up, if i pull over turn the engine off and then on again the light is gone and the car drives perfectly for the rest of the trip. There are no other warning lights and no other obvious signs that anything is wrong with the car (car drives very nicely, fuel economy is nice etc..) This only happens in the morning when outside temperature is 5°C or below. I also noticed that this mostly happens shortly after the car completes a DPF regen. The regen is completed without any problems.
If anyone has any idea what could possibly be wrong I’d appreciate any advice before i decide to take the car into a garage.

sorted bySilly quick thing to check is that the dip stick for your oil is properly sealed in. If it lets air in, it messes with the air sensor and causes it to either run rich or think there's something wrong and go into crawl home mode.
How do you know that regen has completed successfully? (edited)
When it came on, on my Vectra it was doing a regeneration.
