Yeah good point Tomcat, then again I missed the fact it also fails hot sometimes..

Superbee, are you anywhere near Ilkston (Notts)?

Try https://www.marklightfoot.co.uk/ he's one of our members and a PSA specialist. Give him a ring if you are and see what he advises.

Intermittent faults can be hard to track down. You need a skilled diagnostic tech with DiagBox or you could be chasing this fault the rest of your life mate.

Could just be a sticking fuel pressure regulator for example, but without DiagBox....you will never ever know for sure. (Just one more thing you can't test without it)

One question, do you press the throttle when you start it? Never ever touch the throttle on a DBW car while starting it....it's weird others can start it every time except you....? Or has it happened to anyone else like the AA man?

Reasons being the ECU does a DBW pedal basic zero calibration when the ignition is turned on, if you touch or pump the pedal it puts the pedal zero out of whack and it won't be read properly.

Anyway, get yourself DiagBox or take it to someone who knows this system. Or you could still be doing this thread next year....

Isn't the 1.9d (DW8 engine) a basic beast with a mechanical fuel pump (not common rail) and a throttle cable, I think it has a throttle position sensor.

Haas the fuel filter been changed recently?

.

[cancunia]

At that mileage I would be checking the valve clearances especially the exhaust valves as they have tendency to close up and when cold a loss of compression.

From what I've seen of 1.9d starting issues, this seems to be the most common.

Did you get a chance to check them yet?

[Zion]

Ah yeah sorry I forgot it's a cable or TPS.
