2.0 tdi bkd cut out

[danny19901]

hi everyone, i have a mk5 golf 2.0 tdi bkd engine and i really need help i only bought it a few weeks ago and it has cut out on me three times, it cuts out when im doing high speeds down the motorway and the revs are about 3500rpm, i shift the car to netural then it cuts out, when it does cut out the engine will crank over but wont fire back up again the only way it will start is on easy start and then i switch it on and off again and its fine untill i go back down the motorway and it cuts out again, again i have no fault codes in the system either.
when it is running it drives perfect as it should do, i have changed the fuel filter, tandem pump, the lift pump in the tank, used diffrent fuel with a fuel line cleaner each time i fill up but i dont know where to go from here as i have no fault codes and when its running its perfect. please help
many thanks

Maybe a rusted fuelline?

I had similar problem on my 2005 TDI last year, also changed alot of stuff to sort out the problem. Turned out to be a little fuel pipe somewhere (not sure of location of it) it was rusted and had a small whole that let air getting to the system.

ill have a good look around tomorrow, did yours cut out and if it did,  did it start again or did you have to squirt easy start in?

Next time before cranking it over to restart, take the fuel filter housing top off and check the level its at, would be my first port of call. If the filter housing is at the correct level then I would be looking into an electrical issue - the ignition switch failure would be my first port of call for an electrical failure.

Mine shutted down, then it would crank again and drive for a random amount of miles and then go out again.. It could happen in all speeds , and it could happen within 4 min or 40 min 

Really a joy to drive 4th lane in the freeway and then the car shuts down :D Well... it' s what some would call interesting atleast.

If filter housing is below the expected full level (which you'll of pre-check that level when you know your motor is operating correctly as to what the level is) you'll know it's cutting out because of air ingress if it below your pre-checked level.

hi guys
i have checked for any rust or cracks in the fuel lines and they are all ok i have also swapped the fuel pump relays over, im going to go for a run in it tonight and when it cuts out ill check the fuel level in the filter housing
