MOT Changes 2018


The Moog

Recommended Posts

The changes coming arriving in May might have a bit of an impact on some of the chod.

 

The EML being auto fail is one I can see might be a challenge on some cars. As will be oil leaks - if big enough they can be an outright fail. Will be interesting to see how they decide what is a big one.

 

Also will be interesting to see how they decide to test dirty brake fluid.

 

DPF and EGR removals are also straight fail which might catch some people out if they have made those mods.

I was going to say, surely if they take the lid off the fluid reservoir to test it and then a week later your brakes fail that's a potential for a world of shit.

 

I know they've been clamping down on trucks running no DPF or EGR on roadside checks so I'm assuming they have enough knowledge to check without having to take anything apart. No more putting a 2p in the valve?

I think the bulb has to come on and go out again - like ABS tests. So black tape/remove bulb wont work. 

 

Edit : Turn on the ignition and check that the engine Malfunction Indicator Lamp (MIL) illuminates and then goes off. - (h) Engine MIL inoperative or indicating a malfunction. Major

I dodged a bullet with that Skoda then!

 

I'll have to have a proper read later when I get home, the BX has its test coming up in March... last year it got through with an advisory for the smoke that comes out when you hoof it:

 

  • Exhaust emits black smoke during acceleration (7.4.A2)

 

I can't remember the date he gave as a cut-off, but he said on a newer car that'd have been a fail. Fingers crossed that hasn't changed!

The oil leak thing will be arguable when undertrays don't get removed. 

 

The garage that specialises in EGR delete on my cars also does my MOTs...

I always thought EML on was a fail so for the first few times I MOT'd my Mondeo I sat there with Torque on my phone and a bluetooth OBDII reader in the car, pressing "clear fault codes" every 15 seconds. Guess I'll have to go back to doing that.

 

It's the post-cat lambda that's faulty. Nothing wrong with the emissions at all :rolleyes: .

Eh? They already have to remove the fuel filler cap to check the seal, so surely it's no different to that?

Removing a fuel filler cap and not replacing it properly is annoying at most and probably found within the week.

 

Not putting a brake reservoir lid on properly probably won't be detected until your fluid is half water and you're halfway up a tree.

 

Even if they can put it back on properly, there'll be chancers who point the finger at a tester when they have an accident

The eml pops up every now and then on my Accord, literially nothing changes no reduced power, no extra smoke, stays on for between 2 & 10 miles. 

 

It's not been on for the last 600 miles though. 

 

The guy that sold me the car said it'd been coming on and off for approx 12 months with no untoward changes. years ago this would have put me off the car but a £300 quid 54 plate accord you tend not to care much

Its a failure if the MIL doesn't light at all (i.e. inoperative).

 

Also I learnt/realised today, that my MGB is too old (pre August 1975) to be emission tested at all (on an MOT). Good job really, as its chucking out a lot of smoke!

Not entirely true.  Pre 1st Sept '75 is a visual check only (most of my fleet fall into this category), so if your MGB really does smoke a lot it will be down to the discretion of the tester.

Ah yes.

 

Visual inspection (all vehicles)

Once the preliminary checks have been completed, the tester will raise the engine speed to around 2500rpm or half the maximum engine speed if this is lower. The engine speed will be held steady for approximately 20 seconds after which the engine will be allowed to return to its natural idle speed. Once the emissions have stabilised the tester will assess the smoke emitted from the tailpipe. If the exhaust is emitting dense blue or clearly visible black smoke then the vehicle will fail the test. In exceptional cases, especially on certain vehicles manufactured before 1960 where emissions of smoke are unavoidable due to the engine design, these vehicles will not fail the test.

Major oil/ fuel leak is already a fail isn't it, I'm sure I remember SOC saying if it dripped on floor during the test after wiping it was his criteria?

 

Yep on the LPG front EML light has always been on on our RX300, you could argue it like the CAT removal on an LPG vehicle as part of the conversion and no longer required as it refers to the original ECU which is no longer controlling the fueling.

Jeepers. Everyone who sends their car to a garage for work has been putting nuns and kittens in danger for years then! If these people can't fit a reservoir cap, they really shouldn't have been let loose on actual brakes. Someone alert the Daily Mail!

I think it's more the unnecessaryness (that's a word now) of it.

 

If you take the cap off, let's say there's a 0.0001% chance you'll not put it back on properly. As a mechanic, you're now talking about the difference between the 5 cars a month you bleed brakes on and the 40 cars you MOT.

 

Can't they just continue to test braking efficiency? What's the honest reason that dirty brake fluid would be an issue that's not picked up on the rollers?

 

I'm under the impression that a breakdown technician isn't allowed to touch brakes because of liability if it goes wrong.
