I had this problem when I first bought my 1.9PD 105 around 2012. I’ve still got it. 😉 When attempting to start a warm engine, the engine would start briefly but would then stop with a hell of a rumble and thump. The problem was sorted by changing the battery. From what I learned on here, a warm engine requires more power from the battery than a cold engine. Try swapping the battery and see how you get on. Good luck.

I bought my 56 plate Octavia 1.9 tdi Elegance on 4th August 2011after my job relocated to a new base which was 50 miles away from home. After cycling 2 miles to work, I was now faced with a 100 mile daily commute, so needed a motor which could cope with that mileage comfortably and economically. And it was the best decision I ever made, despite a lot of p*ss taking from my mates when I said I was buying a Skoda! 🙄 She coped admirably with the mileage I was travelling and never let me down. When I bought her, she had 44k miles on the clock. She now has 168k miles. I retired two years ago and travel nowhere near as much as I used to but I just can’t bring myself to buy a new car. Recently, an intercooler pipe split which cost me £90 for a new one and £30 to fit by a mate of mine. Besides that, regular maintenance and replacing a couple of rear suspension springs that’s about all that’s gone wrong. If I’m honest, I can’t see myself ever getting shut of it. They certainly don’t make ‘em like that anymore!

I had exactly the same problem with mine when I bought it and a new battery sorted it. I see that you state that your battery is fine. I’ve also read on here that a faulty starter motor can give problems with a hot start as well.
