failed test the other day on a few small bits but the emissions have me worried. it failed on high idle, wasnt that much over tho. what should i do to solve this? the tester said i had a few holes in the exaust that wud affect the reading, plus i had the termostat out n she was running real cold

Holes in exhaust are a no no.We have good used exhaust if you want one and you need thermostat in as they check engine temp by oil so that affects readings also. 086 8226506

going fixn the holes and a have a new termostat to go in today, should that do it then r is der atn else i can do

Put about 1/3 litre of Dipethane in fuel before you go for retest and have clean air filter.Apart from that there is something else wrong??You can get Dipethane in any motor factors for 10e for 1 ltr but only use 1/3 at a time.Do not use other products as this is tried and tested.

Ya i bought a bottle of that stuff too, notn else i can do so only take it down and c

Had that problem with a golf. Emissions were way out. All down to a small leak just before the back box. I'd say when the exhaust is fixed it will fly through.

Failed on emissions again. done all the jobs n got a higher reading :/ . Thinking the cat is gone, any other ideas?

What year is your car?
What were the exact results?

Its a 94. I got 0.47%

looking for a new cat, preferably bolt in

Yup, sounds like the cat alright. Put a 94 thru the NCT last year. Same thing.

We have a selection of cats but you need to measure the overall length incl flanges etc or bring up the old one .They are bolt in type for mk1 usually. 086 8226506
