Does it refuse to start every time it is hot/warm ? Mine did a similar thing but it wasn't everytime just occasionally, enough to be really annoying. I changed the camshaft sensor, and this may just be total coincidence, but i ordered one for a td4 , and when i took out the old one it was a slightly different shape, as in 'stepped' more and skinnier. than the new one. I don't know enough to be sure but the old one looked similar in photos to be for a 1.8lt. I put the fatter one in and two weeks on i've had no issues..

Coolant temp sender???
Had a Skoda Superb which did exactly this and it was the cts giving wierd siganls to ECU when hot.

Getting the codes read would be a good start.

Cam sensor is often the cause of a non start when hot.

I've come across a leaking high pressure regulator O rings being the cause too.

According to Haynes, on the TD4,. the sensor is screwed into the cylinder head . it is visible once you have removed the intake manifold
