Not long after I bought the Octavia MKiv, the SOS fault appeared, then did not recur when I next started the car. Dealer said not to worry........ This has happened twice since, the latest time it repeated each time I started up for over a day, then disappeared. Decided it was time to get it sorted, so it's booked in to dealer tomorrow. Then, on 1st August, I got "airbag error" warning - which disappeared once the engine was running. At the weekend, when I set off, the tablet screen was blank (instrument cluster working though) and stayed that way for a couple of miles, the then the display reappeared. Today, I got t he "front assist not available" warning, which also went out when I set off.
Does anyone know if all these fault warnings have a common denominator in the car's electronics ?
