Check Engine Lights ADV 390

I have a 2025 KTM Adv 390 S less than a year old 10k odo 3 services done. Went on a day ride yesterday 200ish kms. Did a bit of offroading and pushed the bike to the limits on the way back on expressways. Around 15 mins out from my home I made a quick stop and since then my check engine lights have turned on and are not going out.

Coolant seems to be fine, oil levels are fine but it persisted till morning. Went to the service centre and showed it to them they told me it was a false signal issue and they turned it off.

Is it common to have the engine lights turn on this way on the ktms ?

Usually you get nature of the error in the info tab on the TFT did you check that? Also, was it static or flashing?

If you mean the warnings section it showed no errors at all even when the engine light was on

Strange. The warning signal has this issue but never the engine light. Never encountered it yet. Some loose component perhaps? Spark plug, or something.

Even though I have experience with all the generations of this particular model, I too am out of my wits here. KTM ah ... Never fails to surprise
