Hello. I need some advice for a problem that has persisted for a very long time.
I purchased a skoda octavia 2 1.4 tsi 2009 (facelift) 6-speed manual. On the way home, second gear died. I changed the gearbox, then cruise control sensor (clutch switch) died. I changed the sensor and it worked for a few days, then it failed again, this time being followed by the button for the cruise control and also by the steering column. Then the whole dashboard started to light up without any explanation, like for example: I took a curve and lost servo, abs, esp, corner lights, headlights. If I turn off the engine, they usually disappear, but I also experienced the situation where, after turning off the engine, I could not restart it until after 2, 3 attempts. I have to say that with the old gearbox everything was fine.
The car sat for about 2 days without being started, and today when I started it, the errors from the picture below are present (abs, esp and the handbrake light is flickering) . The error code displayed on the vcds is 01130. I know it's the ABS module. I checked all the fuses and they are good, I disconnected and reconnected the main plug of the module, I checked the speed sensors and they are ok. From what I've seen, most cars (VAG) from 2009 have a problem based on the ABS software and have been recalled to upgrade the software.
I need some advice because I really don't know what to do anymore. I tend to think it's a software bug. I plan to go to the showroom, but at the moment I don't have time.
Thank you very much for the answers!

Hello Razvan, welcome to the forum.

First check that your battery is in good condition. A failing battery can often be the cause of multiple fault indications.
