[928uk] Hot start valve

[Paul R Smith]

Agreed. You might need lots of throttle for hot starts.

I don't know what is inside, is it worthwhile blowing through it 
backwards whilst powered, in case something it stopping it closing 
properly.

Also, I probably have a spare. Is there a bosch number on it? I think I 
know what one looks like, but it would be better to check numbers.

Smiffy

Hi Steve

You can run with it ‘deleted’ whilst you find a good used one Steve.
Disconnect the electrical connector  on the valve and block the valve /
return line (you’ll need to be creative here). You’ll have sluggish hot
starts but better that than it messing with your control pressures all the
time.

Cheers
