Hello forum members, i have been getting some lights that wont turn off after engine start, not blinking. (See picture, ommit check engine and airbags, totaly diferent case with LPG)

Oil has been fully replaced a month ago and is full and clean. Check engine comes up because of the LPG system and weird readings for the computer. Battery are charged, airbags are always on due to some cable loose under the seat, didnt care to fix it. When those lights come up, the computer does not switch to LPG at all. Turning engine off and on again solves this problem. Could it be the computer? Its lately hot in here (35°C in shadow) maybe the automatic trabsmission? (Loud R gear shifting) .

Thanks for all!
