Hello,
I have this type of BOSCH pump for repair 0470504002 from a vectr b 20tdi. the problem it has it's that it stops when engine is hot, and it doesn't start anymore untill it cools down.
I've seen the tutorial here on dk bout the vp44 bosch pump repair but this doen't look anything like that. The pump ecu is diffrent. I haven't find any infos aboout this type of pump ecu.
If anyone has any ideas how to repair this type of pump plese help.

Hi, where are you from? I have a working replacement pump with this number

...you can change IWZ(rpm sensor on pump) and it will be OK.If you cant buy original sensor,put new type with little modification...
