I have a 2004 5 door focus 1.8 tdci. I have been experiencing an intermittent problem. The car starts fine when cold. If I go on a short journey, stop the car and try to restart it after 10-15 minutes, the engine turns over, but won't start. The glow-plug warning light flashes. My 10 minute trip to the shops can now take an hour or two before it decides to start again.
Any ideas? Thanks, Mike.
