Hello Dear Friends. I am looking for help. I was drive home today's evening home and then EPC light appeared on dashbord and engine started to lose power. I tried to push accelerator pedal , but there was no reaction. The car was slowing down. I had to pull over and stop the engine. I turned ignitio...

Hi. To be honest, it is final update about tail brake light problem . The issue was between sensor and BCM. There was one wire broken which did not pa's signal to BCM. The wire got isolated and know all work properly. Thank you so much Ciclo for help ans I am really sorry Kamil for mixing up yiur tr...

Hi. I did not know that change anything, because the brake lights were working, after when I took off the led lights and put standard ones again. That is why I did not mention about it. The led taillights are genuine Seat parts with OEM nr. 6J4 945 096 M and 6J4 945 0965 M. Both were taken of from f...

First time I monted new led taillights 2 weeks ago ,just on day I got them They worked properly for all lights, parking, brake , turning etc. There was only error at dashboard showing burned bulb, but there was not problem . Then I put original taillights back , becouse the new ones were birthday pr...

Thank you Ciclo for response. Actually this Seat Ibiza is my present for my daughter. It doesn't have anything. It is a very basic version. It doesn't have anything, even air condition. It is 1.2 engine with 70ph and manual gearbox. I have all prepared for adding automatic headlights and rear PDC sy...

Hi. I checked pin 4 in the sensor connector with voltmeter, and after ignition on , there is 12V power on it. When I pass this power to pin 3 in connector, there is still no brake light. Now I don't know if car lost connection between sensor pin3 and BCM T73a43 , or BCM gets problem with transfer si...

I know, i will try today after my work . Thank you Ciclo

So, I have no idea where is problem now after replacing the senor?

Question, if I combine pin 3 and 4 in sensor connector should it tiggle signal to bcm T73a43 ?

In case you can draw any conclusions ... - The trigger/activation signal is sent from the sensor to the BCM at pin T73a/43 (IN). ... the engine unit receives two signals from this sensor (G100). - BCM power for brake lights and turn signals is +30 (bat) ---> fuse 20 (Ibiza) ---> T73b/13 (IN). - The...

Just for upgrade, mechanic exchange the sensor, but it doesn't help. Still no brake light.
I have to bring my car to electrician for checking

I understand that.
I checked fuse 20 with is fine, so I hope that new sensor will resolve the problem. Otherwise I will be in trouble.

That is strange. All movies and reviews I met, people say that they have brake lights on all the time when sensor is broken.
In my case , I don't have brake light at all

There is everything up side down. Impossible to see the screen from top. Any what I could do, was intuitively put screw driver into the screw, but did have room to use power to screw it out.
I gave it up, because I was afraid I break the screw and then I do more problems.

Hi. Unfortunately after over an hour fight, I give up.
I couldn't screw out the screw. The sensor is located up side down and there is so different acces to the screw.
I will need go to garage tomorrow ask mechanic for this job.

Thank you so much Ciclo. I think you are the most helpful person in the World.
I am sure that many upgrades and fixing of problems could not happen without your help.
I am so glad I joined this forum.
Thanks a lot again.

Now I got a new sensor from my local store. I will try to replace it now.
