    Ok thanks for your help mate. I'll see if my mates free to check that for me.
    Do you know if the pipe from the anti judder should be free to blow through? Ill look into it further tomorrow. I'm hoping this is where my problem is!

    I've bought a transporter so will be selling the car but I just need to get this issue sorted before I put it up for sale.

    The ASV is operated by vacuum so if you can hear hissing you have a leak.

    Is the plunger arm on the ASV moving when you turn the engine off?

    Changed air filter, oil and oil filter today. Also found a vacuum pipe that was worn and I think had a tiny hole in it. Replaced that and it's running lovely now!
    Now to clean it up tomorrow and get it up for sale. Shame to be selling it now it's running so well again!
