Hello guys ! I have a problem and i decided to try my luck here. Volkswagen Passat B5.5 variant, diesel, 1.9 TDI PD AVB, automatically shuts off when hot after one second. Problems occurs when the car temperature is at 90 degrees ( hot ) ( as seen in the video ). When cold, the engine starts perfect. You can see a video with the problem here:

Temporary solutions - When the car is hot and won't start normally, keeping the key pushed in final position and cranking the engine more ( for 3 seconds, even if it started ) will make it start.

What I have tried:

1. Both keys, problem still occurs
2. Oil and filters change, problem still occurs
3. Thermostat changed ( somehow it managed to get broken and water would never get to 90 degrees - this lead to a higher fuel consumption )
4. Changed injectors o-rings with new ones and also cleaned the injectors, with no visible result.
5. Disconnecting and cleaning the MAF sensor.
6. Battery check to see if it is still good ( and it is )

I managed to found only one person in Romania with this problem and me and him tried hard to find a solution in all kinds of services, from official VW to smaller ones. No one could help us with a good response, only with multiple ones. We are somehow desperate in finding a solution. Thanks a lot!
