TDI golf SW 2011 won't start at all

Hi folks, well my fist major problem with our golf TDI SW... 31000 kms.

After refueling the car yesterday evening, I have been driving about 100 km today and tonight, after a 2h sleep in a heated garage, my car was unable to start (the engine was still mid-hot). The starter works but the engine dies almost immediately... The car has just been tow to my dealer... So intercooler issue ? diesel low pressure fuel pump ? HPFP ? exhaust flap ? or simply anti-theft protection (I've tried both key sets) ?

The MFI signal engine error and also ESP problem ???

Also, I don't know if this might be related but I have had some strange troubles since the last 2 weeks with my MFI resetting (lost all my customized functions), and a louder than usual engine noise (a bit more like a « rasping » noise, very subtle)

Will keep you inform tomorrow based on dealer first checkup...

doesn't sound like intercooler. starter cant turn eng over after first cycle and eng sucks in a cylinder full of water from intercooler. good luck..... hopfully something simple and easy.

update : Fuel injection throttle body (OEM 03G 128 063 T) was defect... hopefully this will not come back...
