	2002 1.9TDI PD engine, AWX I think - sticker in the boot is missing. Car is hard to start when cold, runs and drives perfectly when its going. No faults stored. I've checked the glow plugs and they get red hot within a few seconds. Tried starting it with coolant temp sender unplugged so glow plugs have longest time on and it made no difference. I'm guessing a fuelling problem? I have pulled the pipes off the filter and on cranking there is flow through it, I don't have a pressure gauge to check the pressure. Can anyone help? 2 kids and a wife on maternity means I could really do without paying out for diagnostics.... thanks Adam

	could be the starter not cranking the engine over fast enough?

	Probably base injection timing is slightly retarded. If it hasn't had a cambelt in a while then a stretched belt will do that. I've not experienced this directly on a PD injection engine but it certainly happens on the pre- PD ones.
