[evisdaci]

Hello

I have problem with a VW Transporter 2009 1.9 diesel 77KW. When the engine is over 80 degrece of celcius and when I try to start the engine, it start well but 10 - 20 first seconds the accelerator pedal doesn't react. I have change engine temperature sensor, I have check wiring, no error code from DTC but this problem is when engine is over 75-80 degrece. After 20 seconds everything is OK.

Can anyone help me for this problem with Hotstart or another solution. The ECU is Bosch :

labors, thanks for your file. I have the same problem, maybe it is not Hotstart problem, but car have same problem. When it is hot car start very well, but for first 10 - 20 seconds after start accelator pedal doesn't react, after that (10-20s) everything is OK. During the error the battery light stay ON and engine idle is 650 RPM. I have change the alternator but no success. I have check wire from alternator to battery but no success. Any idea please
