Engine Cutting Out

[postiepat]

we have a 2003 1.9 tdi automatic, just after slowing up maybe to turn a corner, upon trying to accelerate the engine will cut out, it seems to satrt up again easily though, fault s 19561 valve for intake manifold flap (n239) open or short to ground & 17957 boost pressure regulation valve (n 75) open or short to ground, any ideas ?? an audiable air suction sound can be heard as driving along also almost like an air leak of some kind

IIRC there is an electrically operated flap that closes off the intake manifold to stop the engine. You probably have a connector issue as you get another (boost regulator) fault too and its probably the same connector. The connector probably just needs a look at, pulling apart possibly cleaning and reconnecting. Dont know which connector though as I dont have a Mk2.
