Failed rear middle and right side brake lights

[alesypalsy]

hi guys, 

I just brought a 2006 1.9tdi octavia estate, when I brought it all was working fine except a front side light and a rear brake light I changed the rear bulb and I changed the front side lights for can bus leds, 

anyway I noticed today when I drive the car bulb out warning light on dash so I checked and my middle and rear right side brake lights are not working , also my front side lights have also stopped working only around 2 weeks old bulbs, 

I ran my ross tech and its shows electrical fault in circuit ,, does anyone have any knowledge where I can look for a bad connection here as I have no idea,  I tried the test with vcds and it was showing 100% power going through to the brake lights but only one left side is actually working, 

can anyone please advise why 2 brake lights are out and why the front sides are also out now, 

where. do I start looking, 

many thanks in advance

Can you post your full autoscan?

I have since disconnected the vcds and it won't let me see the codes now, but if I remember correctly the codes was 00988 lamp for brake light right (m10) 012 electrical fault in circuit

I have also just connected a battery charger to the car as the car had been sitting for around a month while I was away,  it was working fine but I am trying to charge battery fully again just in case this may help

With some LED bulbs they only work one way round.

Have you tried them with the polarity the other way round?

 

Thanks AG Falco

Thanks AG Falco

they were working, I shall try turning them tomorrow, they are only in the front sidelights, would this have anything to do with making my 2 brake lights non functional also?

thanks

Don't think so, but don't assume anything.

Don't assume a new bulb still works.

 

First check every bulb out of the car to see if they are working.

Also try the working bulbs in different positions to see if it is the bulb holder/connection.

 

Thanks AG Falco

Thanks for the advice , I’m a bit baffled as the rear centre brake light is also out and it’s confusing as to where to look for  a point where to start to check connections and earths

Thanks for video , any idea if there are wiring areas to check ?  Fuses?  As I have lost front side lights and 2 brake lights as already mentioned

ok all fixed, I checked the rear bulb and it had fallen out of the holder, so put new bulb in and all 3 brake lights now working, the led seems to have a bad connection as I have to tap the light in centre to make it work some times,  but the brake lights ok now, 

as for the front side lights no warning light is coming on dash for these so I am not concerned with them not working, 

thanks guys

If each bulb has a resistor to defeat the bulb out warning then it will do this even if the bulb has been fitted the wrong way round.

Light emitting diodes only work with the positive on the correct terminal so yours are probably the wrong way round, as previously mentioned.

strange thing was they were both working for around a week then suddenly stopped, I thought as the brake lights had also stopped that the problem was linked but obviously not, 

thanks again
