Hey all,

So this question is more in the interest in trying to learn abit more.

So from what I've read having a checking Engine / mil light on your dash is a fail, what I want to know is?

1) If this was at an MOT council test centre, say it failed for this reason and it also happens to be the last day of your MOT, what would happen? Since council centres don't do repairs, what would have to happen? Would you have to get it towed for repairs to a garage? Or would they pass this and advise since they do not do repairs.

2) Are there any dash board symbol lights that can be on and pass MOT, or are all warning lights a fail? - because not all warning lights necessarily mean what you assume, so a scan tool would have to check, but if you take your vehicle to a place that does not carry out repairs, so I also assume vehicle scans, they could be failing it for something that isn't what the tester thinks it is (you could argue - no?)

I'll answer the first part, the remaining I'll leave to the remaining good chaps on here as its late and I'm tired.

If you take your vehicle to a test station, council or otherwise on the last day of your mot certificate and the EML is on indicating a fault, the vehicle fails the test. You drive it away and either go home or to a workshop for repair, and then you book in for a retest and hopefully a pass will be issued after the satisfactory repair has been carried out.

You can't "unbreak" the broken,you can only break the unbroken to break the break of the unbroken, for me, you cannot unbreak me, for I am already broken,so you have no need to break the break because I am not unbroken.

Just because a test station does not do repairs does not give them the right to pass a vehicle where it should fail ,all test stations and testers must adhere to the letter of the inspection manual and testing guide .

Where a malfunction lamp is illuminated and for it to fail mot depends on what system it’s used for .
Engine malfunction lamps depend on fuel type and year so can be illuminated and not fail the mot .
Some seat belt malfunction lamps can be illuminated yet not fail the mot ,but these vehicles concerned are few and far between these days .

The TPMS light is used to indicate to the driver of a underinflation by illumination but this is not a failure as it’s doing what’s it supposed to be doing ,however the same lamp is also used to indicate a fault with the system which will be a failure ,this is done by making the light flash or change colour

Just to add that testers can’t just fail any mil lamp on a dashboard,only mil lamps that are stated and specific in the inspection manual are a testable lamp .

You sound like your getting bored with your life now lol

You can't "unbreak" the broken,you can only break the unbroken to break the break of the unbroken, for me, you cannot unbreak me, for I am already broken,so you have no need to break the break because I am not unbroken.

Thanks for the detail nitros, as this is what I was kinder alluding to, on the understanding there are mil lights that will illuminate that don't necessarily mean a fail, but would a council MOT test centre go to the length of scanning the car etc. You mention of a list that testers follow. So I knew what I was trying to say but may not of got it across properly, but your response did clarify the hypotheticals I was running through my mind as I lay in bed lol

Here's another one to for testers, along the same line, as my friend has had this come up. His dashboard lights up as it should with all the initial mil lights,when the key is turned to the first position and they go out when the key is turned fully to run the engine. Now his little window on the dashboard that would show you the mileage, date and time has gone blank. The back light still works but your unable to view the date, time and mileage of the vehicle through the usual method?

It's broken

MOT Wise...

Pass and advise.

You can't "unbreak" the broken,you can only break the unbroken to break the break of the unbroken, for me, you cannot unbreak me, for I am already broken,so you have no need to break the break because I am not unbroken.

Date ,time and milage being “lit “on the dash aren’t testable items so it’s not something I go looking for but would be interested in the speedometer being sufficiently lit at least .

The Speedo has to be illuminated and nothing else
