NCT fail on emissions, will dipetane fix it?

Maddenman

How ye, put the 2001 golf through the nct the last day. She failed on
-Parking break imbalance and performance
-Stop lamps ( Need new back unit)
- 1 tie rod
-Wishbone
And mainly emissions,
Low idle 0.48% (passed)
High idle CO 0.53% (failed) So I've to try get it down to below 0.30%, will dipetane do the job??
Also do ya think shes worth fixing up? Sell value now with no tax or nct,shes sporty and nice looking with 18" RS6's is around €900.
If i Get her nct'd would it be worth it? Cheers

Did you give her the aul "italian tuneup" on the way in?

If not, I would go for a spirited drive at higher revs (3500 for diesel, 5k for a petrol) for about 15-20 mins to clean her out.

Mixed reviews for the likes of dipetane, it works for some and not others it seems. Depends what the underlying problem is. You were not that far from a pass.

I've had the same problem today, Car failed on emissions. Should i try Dipetane?

Honey-ec

Yeah, I failed on emissions last time. Added dipetane and flew the retest.

Still have the same car (2005 B6 TDi Passat) and put the dipetane in about three days before the test this time, passed with flying colours first time.

For the sake of a tenner, it's definitely worth giving a go.

Shazzerduffy

That's good to know. I will give it a go better to go with the cheapest solution first. thanks

What were the exact emissions results?

Shazzerduffy

Hi Jim,
Low Idle CO 0.55% Above 30% Fail
High Idle CO 0.59% Above 0.20% Fail

Mmm. High CO shouldn't be happening and it's unlikely a shot of injector cleaner will help much. How's your air filter? Any chance of getting the OBD codes read?

Shazzerduffy

umm not to sure how air filter is?
I had a problem with the engine management light coming on. i took it to a mechanic and he did diagnostics it was coming up as cataylic converter bin 1 or something like that. but he was able to delete it and light went off. However after driving 30 miles or so the light comes on again.
I got the light turned off again specifically for the nct and it failed today on emissions.
I cant afford a big job on the car and trying to look for other solutions for now.
Would you have any ideas?

This could be caused by one of a number of faulty sensors, as well as the cat itself. What make and year of car is it?

Shazzerduffy

It's a Ford Focus 05. the car itself is running fine and no strange noises or rattle from the engine. I really want it to pass the test its stressing me out thanks for your time Jim

You're going to need a mechanic who can read and interpret the fault codes and do a proper component-level debug-and-diag.

Shazzerduffy

Yes I think So Jim. However i will try the dipetane give her a good drive and see what happens if that fails il have to go down that route it get to the source of the problem. I shall let you know how it all goes

Probably died from a Dipetane overdose...

flutered

it passed and he is conked out from the emmisions caused by celebrating.

Maddenman

Haha ye'll be happy to know she failed after that, dipetane dropped it a bit but it's not a miracle worker. Put a new catalytic converter in which set me back 150 fitted so was happy out. She's still going strong today!

Cosmo K

Sell the car, now. Was that a spurious cat you put in? If so, they usually only last a year or two if you are lucky.

Trying to sell her at the moment, people want everything for nothing and don't like the 1.6's!

Tried dipetane for the first time last week for MPG consideration. I run a 1.8 petrol turbo. Absolutely no difference in running or mpg. Pure snake oil.

Had a 97 corolla fail a few years ago on emissions. tried dipthane, no better. had to change the cat...cost 300 including fitting.

Exactly... Why do people fall for this ****e. They'd spend money on this crap sooner than an air filter element.... ever think lack of servicing might have something to do with it?

any advice on whether dipetane will work on a petrol car????the emissions were very very high when it failed its test yesterday,i am servicing it this week and hoping a bottle of diptane will cure the problem also

George Dalton

If the emissions are way off then it's not going to be solved by dipetane or any other fuel additive.

There is only one thing diptane is good for, and that is lightening your wallet.

Its one of those "seems to work for some people/cars"

If it really worked as claimed, it would work in every car, every time.

I think it has a placebo effect on people, and the stuff actually does f all.

Did nothing for me anyway, and I gave it a proper try out.
