Sounds like it might be the lift pump in the tank
I had a similar situation which was solved by replacement
OR
It does sound like a glow problem or fuel starvation - is the tank on or around 20 litres, parked on a hill? This could let some air in and cause slow starting in the morning. The lift pumps are prone to just stopping.
How long does your glow light stay on for? Have you tried glowing 2-3 times before starting?
right, thanks for the replies, as for the lift pump or fuel starvation, good thinking, but when started there is no lack of fuel, it pulls like a train. even the S button makes it leap forward like a big fast leaping thing.
the glowplug light stays on for about 4 seconds, I am assuming this is about normal, it seems a good idea to try letting it "glow" for several times before trying it. I will do that test tomorrow morning.
As for the car being "paperclippable" but not storing codes, there would be no point in the test then. Shame.
I am willing to try the lift pump in the tank, as there is apparently a filter in there, I would like to see this.
Thanks for the ideas, I will update this thread when I have tried "glowing" several times.
