Emissions failure on CT test

[Kaza]

Our van has failed its CT on emissions,changed filter,added additive etc. How many times within the 2 months can we submit for retest?

There’s another tread on here that’s got all the info

Contrôle Technique - any grace period?

Sitting in the garden more like, I’ll disconnect the battery this morning so there is no repeat of re-charging the next time. It’s good to have a backup when you are entirely out of reach of any public transport and shops etc. (even the bar has closed here) and I could let it go but I wouldn’t get a justifiable (to me) price and the high mileage would put people off. So for around €100 a year to keep it basically insured it might as well sit where it is. Lots of happy memories in it too, it only had 66 thousand on the clock when we bought it in August 2008, and, if it wasn’t for my need of automatic in stop/start big city traffic (left knee and right shoulder beginning to give too much pain), I would still be using it to this day.

Drive it like a petrol engine, go through the gears properly and stop pussyfooting around. Take it for a longer journey (50 - 60 kms) and dont go into 5th gear stay in 4th max. By pussyfooting around, you are causing more damage to the engine/DPF with the result it will fail the emissions test.

Why not check this with your CT station ?
As you probably know… when you take your van in for the retest, they are allowed to make a charge… might be zero, might be 10€-35€ … I think…

But, if the problem still persists after the initial 2 month time-gap… you’ll be paying full price for a new CT…

If you’ve done the necessary… why not get it retested… ???

I agree. I did just that the day before the re-test. And I high-revved my car around the local ring road/motorway for an hour on the morning of the test. This was advice from Renault who do my servicing.

Yes we did the same a few years back when selling daughter’s Pug and wanted a clean CT for the buyer so put the additive in it and ran it around for nearly half a day as it had been stood a while, it passed with flying colours and no pollution.
