Hi Peter, No I know what you mean but this doesn't have that. The anti-shudder valve as VW call it.

Good thinking John, although all the pipes are either a hard rubber or plastic. I'll have a better look though and see if I can find a suitable place.

Other thoughts I've had are possibly a duff battery or tired starter. Both relating to high current draw and slow cranking, although the engine sounds normal as far as crank speed goes. I've seen before on the late VWs where the crank speed is slightly too slow for commencement of injection. Thats my thoughts for tomorrow anyway.

Thanks for the ideas, keep them coming! =)

Matt
