Good morning MX driver, I drive a Mazda MX5 (manufacturer’s short name: 7118-492003 8) where the engine control light is on. Error description: Ignition on: motor copont roller light on – start engine: engine control light off briefly (~3s), then it goes on again. I was in a workshop this morning that read out the error memory. However, _0_ errors were stored. Connection to the control unit can be established. As this workshop has little experience with Mazda I was referred to a new car (M). Error memory has been deleted, problem has remained. I would now simply drive on and not think much about it, however I have to do TÜV and they will probably reject the car with luminous engine control light immediately. I already found out that the control unit is installed in the footroom of the passenger. Battery changed a few weeks ago. It can be because since then I have not all the sensors out I’ve been driving 30km since then – but no motorway. Now I wanted to hear out what you would do. Do you know good workshops that get your Mazda in the Munich area in your hands? Can I do something myself? Dear greeting supplement: When starting today, the speed indicator in the cockpit was short and showed 0 RPM. Passed after I switched on the windscreen wiper. Level 1 didn’t work, level 2 already, but the speed indicator did not work. Both symptoms “disappeared” after 2-3km. Wipe and display go back. oO Other: oil temperature minimum over the 50% of the display.
