Fixed the problem. After removing the trim panel near the footrest, the plugs looked like this. After cleaning them with contact spray all came back to normal, car's systems are alive again. Next thing is to take care of the clogged panorama drains. Thank you everyone for ideas. So if someone has this problem and has panorama roof, then it shows where to look for the solution.

This is the only thing that points to some hardware fault, two rear speed sensors. Of course it was working flawlessly before and the car was standing still during the weekend. In all other modules I get the U112300 error :/ Only the DSG is free of codes, engine also throws this U1123 code but works ok. Could it be caused by the d*** water?

So we can be sure that it is caused by the water from blocked sunroof drain pipe, but what exactly - I have no idea and don't know where to even start.

Tried with a drive - nothing helped.

I have 11.9-12 V on ignition, when car running 14.4-15.1V. I would go for a short drive but I am little scared - as the Brakes fault flashed on red, so I am assuming that brakes won't work.

Above photo is not my photo. As for my Battery, it is in good condition, charging is good aswell. Checked also few fuses and all are good.

Thank you. I found that under this trim there are some wiring harness and few plugs: What are these for? If they were flooded with water, is there a possibility it caused those faults? What about CAN Gateway module? Could it be damaged aswell?

Hello everyone, I have a big problem. I am quite new owner of Octavia 3 vRS 2014 (model year 2015) diesel. This is an estate with panorama roof. Problem started when I discovered clogged drain pipe on driver side (I have LHD drive car with steering on the left). This is what was happening just yesterday: Today, I wanted to start a car. Turned on the ignition, and almost all electronics was faulty. Brakes faulty, Power steering faulty, hill hold faulty, tire pressure sensor, ESP, AFS system, ACC radar. On the OBD Eleven on almost every module there is a U112300 error code, static. Car starts normally but I am afraid of driving it in that state. What the heck could go wrong and where to start ? I know it is due to blocked sunroof drain and this water, but what exactly could happened?
