    No prob.
    I'll throw it in the back just in case as am heading down anyway.
    Any other bits you need give a yell.
    No engine case but some of the ancillary bits including really good heads, throttle body, relays etc.

    It's starting to rust out.
    Might be ok short term to get mobile.
    You can have it if you want.

    Hi UK Skippy, only reading this post now. If your still having issues, I can help out if you need it. I'm in Bris, north side. I'm no mechanical expert, but can help check the basics. I have a fuel pressure gauge, and can show you how check the main items in the EFI system.

    Cheers Andy much appreciated, I took it to Scorpio on Saturday and he phoned today to say the Cat Converter was clogged and suffocating, it was a very quick call so I hope for firther clarification when I pick it up later in the week. I will post the full diagnosis on here once known so others can learn also. Who does the work on your T3?

    Maybe it needs a conversion to a “High Flow Cat”? - Empty out all the broken and collapsed ceramic internals, and fit a straight piece of pipe end to end. :rolleyes:

    Works a treat, and will never clog again. ;)

    It wouldn’t be the first VW, old or very new, to having emissions slightly different to what was promoted at the factory. :D

    You still need the muffler....:cool:

    Just the Cat Converter before the muffler, needs a little work.

    They don’t clog overnight, and would have been well clogged when you first drove it. Rectified, I’m sure you’ll be impressed with the improved performance. ;)

    The longer muffler might be right size if sans converter ?
    Get onto mech before he blows the budget on new parts :)

    Funny how there is no 'follow up' of original registration requirements;).

    Hi All, the final verdict was clogged and collapsed CAT, so took Grantus advice and emptied her out and the straight pipe straight through and put on a new muffler to boot. It's running great and I can even go up a hill again!! See below photo of the remnants of the CAT. I hope this post helps others who may experience a similar problem, there was great advice on here and it could have been any of the suggested scenarios listed. To work out if its the CAT you should be able to tell by hand over exhaust pipe, if its not flowing out like it should be it COULD be your CAT.

    Some humour to finish the thread;). A cat is something a dog chases:D. Don't know my dog would chase those contents tho'.
    So...UK Skippy if it's not getting to the exit of the exhaust it's choked before & if it can't get exhaust out it can't get more air/fuel in:(.
    Nice Grantus had the cheaper answer!
    Cheers
