Mulfuncion of servo steering wheel, ABS, Traction control, TPMS, parking senzors (maybe more :) )

Hello!

I'm talking about Skoda Octavia mk3, 2014, CKFC engine, 4x4 (not scout).

First coldish morning after summer I had small problem with starting up the engine. It wasn't cranking to start up, but it took 2-3 seconds more than usually.

Slight after engine was running few warning lights turned on; servo steering wheel, ABS, Traction control, TPMS, parking senors, hill hold (there isn't warning for that for that, but it doesn't work). Engine works OK, no check engine light, no vibrations, no extra noise.

Of course I thought about bad battery. Later on I started engine again, same thing. I changed battery and re-calibrate BMS, same. Meanwhile i checked all fuses. All of them are OK.

Maybe corrosion on GND?

Anyone with same experiences?

How did you solve them?

Any other idea?

I appreciate for all the answers!
