Title: Emissions test-please give advice on how to prepare..
Post by: Jasikasisback on 09 July 2013, 11:02
Finally taking the golf for the MOT...although it had some difficulties with the emissions test last year. so I am not holding my breath this year...at 135 000 miles it may be the end...

Anyway I will be doing the following for the emissions test:

Change the oil and filter a few days before the test
New air filter
Plugs and dizzy cap changed 5000 miles ago...plugs still look ok
Coolant  changed three months ago
Put premium unleaded into the tank before the test
Drive the car on the motorway for 45min before the test

I was wondering what additives people have used and if any have helped. I have put redex cleaner into the petrol tank and hope it has made a difference (about two weeks ago). Maybe an engine flush (Wynns/Halfords other brand is good?) would make some sort of difference?

Would be nice to get another 12 months out of the Golf..:)....

You can try some redex before the test. i have done this before and magaed to get one of my cars to pass.

I had aother a few years back - failed, went off for 20 mins and gave it a good boot, drove it straight back into the garage and the emissions were read straight away and passed.

Take the Lambda out and clean it.
Injection cleaner.

If it fails

Try another test station until you find one it passes on! :grin:

I've been advised not to remove the lambda as it is difficult to get out abd the threads usually get damaged and you can't replace it. Besides the point, what do you clean the deposits off of it?

Fit a second cat for the test  :wink:

The cat could be the reason why it was difficult last year.

Well I highly doubt they will go for that..I have a spare catalytic converter, but have no idea how to test it to see if it is good or not....

I was told that one on mine mine was about 0.20ppm adrift of passing so the tester added some additive and it got through  :grin: i shall do the same just before i take it in next year can't see the need to replace the cat  :lipsrsealed:

Who ya gonna believe? Some bloke in a pub or somebody, such as myself, who has had the problems and sorted them! And yes I have taken out a Lambda, cleaned it and put it back!

I believe you Len. Just afraid I'll damage the threads and MOT is tomorrow..so am quite wary...vagcom does not say ig is faulty but could still be clogged up...:)

If you worried about the threads, then just take it out as if you were treating a sparkplug. Loosen it a half inch turn, tighthen, the loosen again and repeat until it comes out.

I think your over worrying  :grin:

yeah buy a caravan:). nah I need a people carrier. I don't think I'd get more than £300-400 for the mk3 as one automatic similar specs went for £350 in my area. They are cheap now. Rather park it up for 2-3 years in a barn and see what happens, really should've stuck it in the barn in the first place:). Only got one parking spot :)
