My '03 Bora 130TDi developed engine problems. It was mapped an showed a faulty injector. This was replaced with a recon unit (£150 exchange), but still cut out at high engine revs.

Next to be changed was the tank fuel pump (£40 second hand). The engine runs fine now but is a little lumpy on tickover, especially when parked on a downward slope.

It makes no difference whatsoever the engine being hot or cold. It has also had a service at a VW main dealer this week and they made no comment!

Anyone experienced similar or know of a fix or adjustment?
