MTDI Bosch VE won't shut off
MTDI Bosch VE won't shut off
I've build a mechanical Bosch VE pump for a 2.5 R5 TDI. Basepump is a Rover Mechanical TDI pump. Engine runs great, but when i want to shut her off, she keeps running irregular. Pump is tested, nozzels are tested en stopselenoid is tested. All ok. Anybody a idea what's wrong?

the pump should shut off when 12v is taken away from the solenoid. Do you have voltage at the solenoid when it's shutoff?

Some I have seen have mechanical stops

Any picture of the pump? There are several different styles of VE pumps,

That is a very common cause of such problem.

I had the pressure tested and it was way to low. They shimmed it to a higher pressure. Before i didn't get any black diesel smoke. Now i do. I can shut it off with the mechanical lever.

Wow, not common to see mechanical pump with injection advance selenoid.
