New 2018 MOT Rules & How They Will Affect You

*New 2018 MOT Rules & how they will affect you…

*New stricter assessment of diesels fitted with particulate filters from May

*If any visible smoke is emitted from the exhaust the car will fail the MOT 

*New defect categories also being introduced – ‘Minor’, ‘Major’ and ‘Dangerous’

*The latter two will result in an automatic test failure – Minor will still pass 

*New inspections of reverse lights and brake discs will also be introduced

New stricter MOT rules for particulate filters designed to reduce harmful exhaust-pipe pollutants are being rolled out by the Government in a bid to crackdown on diesel cars.

A new MOT Inspection Manual draft document states that any vehicles fitted with a diesel particulate filter (DPF), should be checked so that ‘no visible smoke is emitted from the exhaust during the metered check’.

If smoke is detected, the car will automatically fail the examination which is bad news for those of us that roll coal!

MOT testing stations have been required to check for a DPF during the inspection of the exhaust system as part of the MOT test since February 2014.

The vehicle will ‘automatically fail the the roadworthiness check if the filter had been fitted as standard but is found to be no longer present’, the Driver Vehicle Standards Agency says.

The changes due in April will require an inspection to ensure these filters are functioning correctly, else the car will fail under a ‘Major’ defect – one of three new criteria that will also be added to the test in four months’ time.

HID’s installed into halogen headlight units will now get a major fail even if the aim is correct. It has always been an offence to fit HID bulbs to halogen headlamps so the MOT now falls in line with that.

Reverse lights are now part of the MOT for any car registered from 1st September 2009 (59 plate onwards). Daytime running lamps (DRL’s) & front fog lamps must work on vehicles registered from March 2018 (18 plate onwards).

Engine Management Light is now a major fail. It must come on with the ignition and then turn off when the engine is started.

Brake pad warning lights are a major fail

Handbrake with excessive travel is now a major fail. Before it would only a fail if there was no reserve travel.

Contaminated (dirty) brake fluid is a major fail. Not sure how that will work as the MOT tester isn’t allowed to remove the fluid cap.

Oil leaks (engine, gearbox etc.) can be a major failure if they are deemed large enough.

It seems they have removed the failure for tyres not being fitted according to sidewall instructions. Inner/outer or rotation incorrect.

Any modifications/removal to emissions related devices, this includes DPF’S and EGR’s is now a major fail.

Where a DPF canister has clearly been cut open and re-welded, it will now fail.

A vehicle fitted with a DPF that emits any kind of visible smoke during the metered test will now fail

Emissions limits for diesels registered on or after 1st of January 2014 have been reduced. All diesels will now need to pass the limit that was set by the manufacturer when the car was new. This can be found on the VIN plate. For example the current limit for your diesel car may be 1.50. That could change to as low as 0.30 with the new rules.

Let us know your thoughts on the new rules Landy owners!
