Mot changes 2018

[mighty kitten]

The most worrying part of the new diesel tests is that anything pre 2008 that has a limit number on the chassis plate is tested to that limit from the 20th . For example a 2002 t4 transporter would have been a 3.0 limit for a turbo diesel will now be 0.3 as shown on the plate usually in the bottom right corner . A lot of older stuff is plate value around or lower than the new 0.7 limit for Euro 6

Why don’t you just fix it ?

It is my intention and would be the simple option, although the EML's often continue to show up even when fixed, hence my concern. Basically there is a unit which controls the dual-stage manifold which can often fail or in the case of my car work but occasionally stick when operating (it switches to the long intake runners on start up and the short ones >5000rpm). If it fails you lose a chunk of low end torque and it ruins the fuel economy (it's not great in the first place!).

The point behind my post was it is silly that a small running issue should now be an mot fail, the emissions will still be ok in this situation and it is not dangerous or notably harmful to the engine. It is a hard one to judge as other issues that throw up an EML may be somewhat more failure worthy, but annoying nonetheless.

From the MOT handbook applicable from May 19th onwards:

Thanks. Is there a link to this handbook? I am reading from this: https://www.mot-testing.service.gov.uk/documents/m...

and have read through this as well https://assets.publishing.service.gov.uk/governmen...

And I still can't see the wording from your image anywhere.

Luckily this rule doesn't apply to motorcycles so it went through the MOT just fine on Saturday.

Sorry you appear to have been misinformed, next year it will fail.

"Some motorcycles may be fitted with high intensity discharge (HID) headlamps. Existing halogen headlamp units shouldn’t be converted to be used with HID bulbs. If such a conversion has been done, you must fail the headlamp."

Oh

Section 8.

So your car can pass Section 8 a-g with specialist and calibrated equipment, but will still fail (major - requiring repair due to safety &/or environmental impact) due to the manufacturers EML indicator not functioning correctly although functioning inaccurately. Yes the EML indicator may be used for non-emissions testing as well, but seems excessive as a major MoT failure on its own.

Mine passed 5 days ago with HIDs so I get another year with them in before swapping to halogens for the test

Remember the new system is live today so check your reversing lamps etc!

I am not looking forward to this weeks testing, especially diesels and cars that have had the engine light on for years due to heater circuits on lambda sensors going bad....It's going to be fun explaining why previously fine cars are now fails!

On the up side, they have added some things that should have been testable all along like propshaft bearings.

And taken some good ones away like incorrectly fitted tyres and damaged valves.

First used after 1 September 2009 says the gubbmint? (reversing lights)

Where does illegaly spaced number plates (or font) come in? The criteria for major fail for example is dangerous or bad for the environment.

I take it there are some exceptions, like the above ttty number plates that still mean a car will fail?

My biggest concern with these new changes are ‘fluid leaks which pose environmental concerns’... how do they define that? If you have evidence of a leak on the engine will that fail, or if it’s only dumping oil/other fluid over the ground?

I drive a R53 mini, which are well known for dropping a bit of oil here and there, but is that enough to constitute a fail? Given the price of r53’s now I can’t see many owners going to the expense of tracking down the leaks to get it through an MOT, which would be a shame.

I am sick of having to hit the re-circ button because of polluting diesel vans, trucks and cars.

I hope the new tests will fail these vehicles like this discovery.

Yes me too - very please to read about this part:

"A diesel vehicle will fail its MOT if there is smoke of any colour coming from the exhaust or there is any evidence that the diesel particulate filter has been tampered with."

But I hope it applies to petrol cars too!

minor oil leaks pass, major ones fail. r53 leaks tend to be pretty small.

I agree with the diesel stuff but I do feel for the less affluent folk who rely on their old smoker to get through life.

I know health and emissions are totally paramount but some people can not perhaps afford to lash out on a newer car or pay to fix stuff that was once ok for an mot.

Life's unfair and yeah they should have tried harder at school etc etc but nevertheless it's the poor who will take the pain.

[Pica-Pica]

The Gov. site is mis-worded
It says “There are stricter limits for emissions from diesel cars with a diesel particulate filter (DPF).”

No. The limits are the same, as the particular EURO standard the car was built to. The test is better prescribed to check that limit.

We can measure it !

Quote: A leak of fluids such as engine coolant, screen wash and fluid required for Selective Catalyst Reduction aren't reasons for failure. You should fail a vehicle if a fluid leak creates a pool on the floor within 5 minutes that's more than 75mm in diameter or if there are many leaks which collectively leak fluid at the same rate.

HI there, newbie here.

I am trying to get a Jaguar X Type AWD 2.5 v6 sport (07 plate) which has been SORN for about 12 months ready for sale and plan to have it MOT'd before hand. I am a complete novice at cars, but have managed to change the rear parking sensor...

Anyway, the side indicator repeater isn't working - I've changed the bulb but still no joy (front and rear indicators work fine). Will this be a fail for the MOT?

Thanks in advance

[Athlon]

Yes, side repeaters must work.

[tvgirl30]

Okay thank you! More investigation/remedial work required before the MOT then!
