Thanks. I removed the MAP before I cleaned the manifold (not that I knew what it was called). I cleaned it out as best I could, looked really good when I'd finished (all the bits I could shine a torch in to see anyway.)

Ah great... I've gotta pop out for a few extra tools today anyway (ready to fit the new VCU at the weekend) so might run down to the car parts place and see if they have any pipe in stock.
Thanks for the info Re 3.5mm pipe... I assume the pipe is just push on so better to have it nice and tight.
3.5mm ID is the standard German vac pipe size. It's used on all German made engines from BMW, Audi, VW and Mercedes.
It needs to fit securely without being so tight that it's difficult to fit, or it just splits after a while. I've tried 3mm ID in the past, and while it works for a while, it soon splits where it's pushed on to the fittings.
