    Clean the throttle body and install a new set of plugs (if not already done so) just before the test or retest.
    You might also find a bit of useful info if you input "VW Golf 1.4 Emissions Fail" in the Boards.ie search box.

    Post the complete readings or an image of the fail sheet, more info the better. You will probably get more replies then.

    Dipetane fuel additive may work - put a hefty amount in - worked previously for me after failing on emissions

    I'd be a little wary, 19 year old engine, it could expose problems with seals and tolerances

    I was absolutely serious. However it was also a complete brain fart, having been discussing engine cleaning additives (as opposed to injector cleaning additives)

    I had forgotten all about the post, but thanks for pointing out my stupidity :D
