mk4 gt tdi 115 hot starting problem

[FR0GGY]

I have a tdi golf 115 that I brought a few months ago, when starting when engine is hot it takes 4 ish seconds to start,but when cold engine fires right up, upluged the engine coolent temp sensor and she fires up everytime when hot, so I brought a new sensor but this didnt help also tried a bigger battery but again didnt help, any ideas guys and girls?

Have you checked the cabling and socket for the temp sensor as well?

The PD engines are so dependent on their sensors that it'll be hard to tell without getting the fault codes off it...
