Is loss of power an MOT fail?

jsmoke · 8 May 2019 at 15:33

I'm getting an engine error which relates to fuel malfunction with the injectors. It basically mean there's an incorrect air/fuel ration getting to a cylinder. I've been told the injector o ring(s) may need replaced or the inlet seals.

Is this actually an MOT fail, it's not directly a safety problem is it, just like a slipping clutch is not a fail?

Is the EML on? Wonder if an EML light an MOT fail these days?

hmmmm loss of power is not a safety problem ?

If the EML is on then pretty sure that can be classed as a failure, also if it's not running correctly (loss of power would it not be burning fuel optimally) could that make it fail emissions?

No, they have no interest in how much power you have. It probably will fail on emissions though.

With your recent threads on "how to buy insurance", and this engine light....I am rather curious what car are you looking to buy or bought now.

Engine light on is an automatic fail under the new MOT rules.

I think any warning light is a fail isn't it?

I had taken my passenger seat out a while back to make space for stuff and as such had the passenger airbag warning light illuminated. I phoned the garage to ask if that would fly and was told the light would cause a fail. They didn't seem bothered about whether my car had a passenger seat or not, just that the light was lit.

AFAIK (but not looked it up) a warning light on any safety feature is a fail - not necessarily any warning light. They won't got into specifics as to why a safety feature warning is on and whether that means it might or might not be a problem.

EML, ABS/ESP/VSA, Airbag, TPMS, Brake fluid warning lamp. I think thats all the lights that are on that would fail. For op, if no eml then only emissions would be a concern.

Looking it up, seems like EML is an instant fail.

Bad injector seals will kill the engine eventually though. So might not need to worry about the next one

I love all the talk of "instant fail" and "automatic fail" that you get in MOT and law breaking related discussions.

Instant fail as opposed to what? A belated fail? A gradual fail? An epic fail?

Put stickers over the warning lights.

That isn't going to help.

Always made me smile that.

As in once they see they will fail it straight away, they won't even bother checking anything else

It is not permitted to abandon an MOT test part way through once you have started unless it's for safety reasons - the whole test is completed even if the first item that's checked is a failure.
