300 tdi cutting out at peak revs

[scotyp]

Hi all,

I have a 130 with a 300 tdi and just as your about to change gears, I suppose peak fuel demand the motor dies, back off the throttle and away it goes again, I am assuming its a fuel problem, maybe its not! I have drained the water seperator and the fuel filter thinking condensation but nothing unusual there,

is it possible to service the lift pump or check the operation

would appreciate any thoughts,

thanks in advance

Scotty

only likely to be 3 things

1. a blockage in the fuel lines or filters (most likely)
2. a collapsing air hose
3. a blocked air filter

if when it cuts out it doesnt blow black smoke then its a fuel line issue

Could also be a leak (hole) in the boost compensator diaphragm on the Injector pump, Regards Frank.
