Good morning, I cleaned the cockpit yesterday with my bus. Even a little damp. Suddenly the warning flashing system went on. Thought… ups, maybe there was moisture in it? Switches removed, it still didn’t go off. But it still jumped on. Battery jammed several times. At the latest after 3 minutes the warning flashing system went on again. After the 3rd test it didn’t start any more. I put in a dehumidifier overnight. Warning flashing system no longer works from s However, it no longer starts. The light of the immobilizer always flashes. At the start attempt it flashes fast. Motor orgelt. Light radio etc. works. It has no central locking and I have only one key without IR bulb. What should be my next step? Thank you in advance, Greeting Marco
