Just been told that the Zed has failed its MOT.

 

Apparently it was giving out dense blue smoke when idling and so it failed the emissions test.

 

Any ideas on what can cause this, is it serious or could be?

 

Cheers

what year is it?

 

anythign registered before Aug 1992 cant be tested for emmissions, they dont apply

 

i had mine tested, it failed because it was decatted, when i told the bloke it was fine the emmisions dont count because it was a late 1989 model he asked for prove

 

took out the log book, checked it, then printed off a passed MOT ;)

Errrm it still has to pass the emmissions test, it just doesn't have to be tested for a cat. Otherwise it could chuck out any old crap.

 

Mine smoked on idle after about 5 mins but the tester allowed me to switch of the ignition and restart it as this usually sorted the problem..

 

Hope you get it sorted bud

Think you're getting confused with a Cat test and an emissions test bud.

Hmm, the blue smoke might just be a bit of excess oil burning off, or maybe due to the PVC valves being in need of replacement. My tester took the car for a quick run down the street to warm it up and the smoking stopped (my pcv valves are in need of replacing) and the zed easily passed the emissions test.

 

Due to the age of my zed it still has to pass an emission test, but its really generous due to the pre 92 car regulations.

 

HTH

Well yesterday I took my car for an MOT at Nissans and this is where it failed. I wasn't convinced by the failure as I've never seen blue smoke before when idling, yes I've had abit of smoke when idling for along time in a traffic jam, but it goes away after the traffic clears and I get going again. Anyway, today I took it for a good rip and then took it to another place and it passed without problems, but obviously there is a problem and maybe Nissan were just being abit too fussy I dont know, but maybe its the PVC valves as stated.

sounds like examiner was looking to fail it he,s supposed to run engine at 3000 rpm for about 30 seconds to purge exhaust, doing this would normaly clear any smoke in my experience, in ten years of testing ive only failed 2 cars for excessive smoke and they both had obviously worn engines .

dont take your car to nissan full stop, they have a habit of pulling peoples pants down and ****ing them up the arse :rolleyes:

 

go to a normal mot station bud

Yeah the MOT place that passed me, got me to rev it to 2000rpm for about a minute and that then cleared it and passed emissions test. You are probably right as well about Nissans, I think I'll avoid them in the future as this is not the 1st time they've messed me around with false information.
