Search for calming (ABC: Find a workshop)

Hello dear people, I am looking for someone who says to me: “This can only be a small thing…” 😉 Yesterday I was at my parents’ weekend home, so you have to cross a non-paved road. So I set the ABC chassis to the highest level and when driving down the road I somehow felt like a short brake test for inexplicable reasons (wheels blocked also briefly on the gravel). There sounded a small signal and at the instrument cluster was read “ABC – Werks I thought only “Sch….” – that will be expensive. (The connection with the braking was perhaps no one at all, but a pure coincidence!) So, after I had then turned off the car and drove back home an hour later, the error message was no longer detectable. “No faults”. Also this morning no more, nothing. I should perhaps say that everything was completely wrong” (but not in red, as I found it in my Internet search, but “very normal). normal worked, i.e. the car could be driven up and down completely normally without abnormalities, there was no “misfunction” on the part of ABC to notice, as far as I can judge and feel this as layman. Couldn’t that have been just a “harmless” message, because maybe the oil level is a nuance too low (no idea what causes this could have) or must I be prepared for the worst? (Wednesday I have a workshop appointment, for safety reasons). Request for reviews/opinions. LG, Jonny
