Hello! With my S320 with Prins gas system I drove the gas tank empty this morning and as always the system then jumped on petrol. At the same time however the engine control light approached and the engine was in emergency run. Shortly later in the parking lot I still parked in trek mode. I started off and again: Lief again normal, only the lamp remained on. In the manual it says that the lamp after emptying (from the petrol tank) after 3-4 start operations is extinguished. I also try, however, without success. Does this happen every now and then, that happens with the LPG-learing? (Was now the first time) Does the lamp only turn off in the workshop? Thanks already for the tips. Greeting Kai
