Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

1.4 01 Petrol VW Golf - fails on emissions

    1.4 01 Petrol VW Golf - just failed the NCT for the 3rd time this evening.

    The CO was 2.8. Had a new exhaust fitted (as it was leaking) which didn't improve the problem and was then told a new CAT would solve the problem but having re-tested only reduced the emissions to 1.7 - far above the limit of 0.3.

    Is there any hope of reducing these so dramatically or am I wasting my time?

    Ok how does the car run in general, does it hesitate when accelerating? Its hard to diagnose without further tests, but I would be looking at fuel system for problems (injectors specifically) or a badly switching lambda sensor.

    How much oil does it use.
