Hi,

Very much a newbie - in fact my first Superb isn't due to arrive until June.

Perhaps a silly question, but are DRLs part of the MOT? By that I mean if the DRLs are deactivated would it mean an automatic MOT failure?

Thanks

Peter

No, DRLs are not 'testable items' so the MoT test cannot officially 'see' them.

Great, thanks

What if the car had DRL's fitted, and activated, but one side had failed i.e a blown bulb?

 

Is this a fail?

 

What about the rule about lighting needing to work if fitted? For example it is possible to fit a rear fog light to a car that does not legally require one, but if that retrofitted fog light fails then the car can fail it's MOT, despite not needing a rear fog light in the first place.

 

I appreciate DRL's are not compulsory on cars manufactured or launched before February 2011 but I suspect a failed bulb might be something the MOT tester might have to mention, perhaps just an advisory?

 

With regards to deliberate deactivation, then I appreciate this is not an MOT failure.

 

However, I was on the understanding that the option to turn on / off DRL's in the cars (Maxidot) menu is being removed on new models due to them now being compulsory. The ability for the driver to turn them on and off was there purely down to their use being optional when the car was designed / launched.

 

Despite a brand new Superb (MkII Facelift) being available, as this car was type approved before February 2011 then the ability to turn them on and off will likely remain...

Pretty sure under construction and use that all lights fitted must function . Not the same as an mot of course but means a faulty light can't be ignored

DRLs aren't testable, if they were activated and one wasn't working, I'd advise it out of courtesy.  Some DRLs are designed to dim and act as position lamps which are testable, though it would be a silly design that would prevent them from functioning as position lights if they were deactivated.

 

One anomaly with the test is that if a nearside rear fig lamp lens was broken and it was showing white light to the rear, it can't be failed as it's not testable, only the offside rear fog lamp is testable.

OK, I'll come clean........

All being well I should get my brand new Superb delivered in June. I know that the Common Market has since 2011 required DRLs on new cars, but to be frank I don't like them. (I'm not going to get into a "discussion" of the pros & cons, please just accept that that is my view!) The first MOT won't be until June 2018, but the reason behind my question was:

A If the DRLs are deactivated, does this mean an MOT fail?

B An MOT fail means that the car is essentially not roadworthy, therefore

C By deactivating them I am effectively making the car unroadworthy for the first three years before it is due for an MOT.

I just don't want to fall foul of a bored patrolcar occupant!

No , there is no requirement to have DRL on , you can switch them off if you wish , however it's not an option on all cars , can't see it being a problem on the Superb though.

For the mot even if they do become testable then you need only to switch them on , just like fog lights for example

Thanks, Rich

No.

No. I can turn the DRL's on and off on my 2011 Superb as I see fit through the driver accessed computer menu.

 

There are still many different 2015 registered cars out there without DRL's, I'd imagine the Police wouldn't even notice, let alone be bothered to have a chat, not that they could do anything even if they did.

 

Now, as for the reasons why you want to turn them off... just kidding

The requirement for drl is based on when the model gained type approval rather than manufactured or registered and cars that gained type approval after 2012 should have drl .

Not sure if a facelift requires type approval, I doubt it , but drl were a selectable option on the 2008 Superb although it just switched the sidelights.

Back in the 1970s, I had a Fiat 128 3P with had twin headlights that started to corrode. I replaced the outer headlights that worked on dip and main beam, but left the original inner headlights that operated on main beam only as main beam was adequate. When I took it for MOT, I was told the inner headlights were a fail, unless I removed them. I did remove them, got a pass and put them back again afterwards.

The car was turning to rust and it wasn't worth spending any more than necessary to keep it legal. According to how many left, in the UK there are currently 7 licenced and 8 on SORN.

Thanks to you all. Now, when the beast arrives, and after a year or so when I manage to get my head round the instructions, I'll deactivate them with a clear conscience.

Nice try, Silver!

. According to how many left, in the UK there are currently 7 licenced and 8 on SORN.

Surprised there are any left at all at this stage, they must held together with rust and body filler now! My first car was a Fiat Brava and although nothing like the older generation Fiats it was still a load of rubbish - then I quickly got sense and bought an Octavia
