MOT failure

[Bugged]

Hello

I’m after some advice, my Multispace failed its MOT today on its emissions, apparently they now need to be lower than 1.5 something or other, and the best the guy could get is 3.2?

This is all new to me, but hey ho, we are where we are. 

The engine was cold and the van hasn’t been on regular long runs, I understand that this helps, I also put some fuel additive in the tank to see if this would help. Does anyone have any tips on how I can improve this, so that I can get it over the line? I will be giving it a belt up and down the motorway before going back on Friday. 

TIA Regards

hi..what grade of oil are u using......i use 5w30 fully synthetic LOW SAPPS, when was it last serviced..
ask garage to test emissions first......put aditive in. on a low tank of diesel..and go for a blowout[low gears high revs] 1/2hr. 4th gear, over 50mph,keep it in 4th...
dpf could be clogged up..have good read on this forum,you will find your answer.........

Hi 

Thanks for the info. Not sure on the oil type, by mistake I let a complete idiot service it recently, knowing him it could have been olive oil. I have already put an addictive in, but I’ve got a full tank. I’m going to give it a big blast on the motorway over the next couple of days, and see if I can get the numbers lower.
Cheers

A new air filter is a good place to start and not expensive.
Also a hot engine is a must, my guy tells me to do 10 miles before bringing it in for testing.

Put a bottle of Millers fuel treatment in the tank and go and give it a Mexican tune up, obviously check the air filter and replace the fuel filter first.

The oil will not make that much difference to soot output (which is all the mot test for) but check when it was last changed.

Thanks Guys

It had a full service done back in March, new filters etc. It’s back in tomorrow, so it’s going to get a 4th Gear, 30 minute blast at 50mph, to give it a good blow out.

Won't hurt to put some injector cleaner in before you go.

Interesting... Maybe if your plate value is lower than the default you could somehow obscure that part of the plate? But in this case, the garage seems to be aiming for the default of 1.5

Sounds like you are throwing good money after bad. If your service man used wrong grade of oil your engine is at serious risk of turbo failure. The oil needs changing soonest. I would suggest you just book it into a Citroen garage for service & Mot. If you check Citroen website you will see that cost is comparable to any other garage that will actually do a proper job.
