This car has already taken my sleep away. I replaced his ECU with a used one, since it is no longer new, however, this one was still sealed, as I had to open it and send it to a factory reset to be able to turn it on in this car. With the ECU reset, it turned on, ran a few days later and appeared on the panel again, "Engine failure", blinked three times, the car did not fail, and did not turn off, and disappeared, as I am walking with the Scanner connected, I already looked at what was the error, it gave a failure error Coil n°2 and something similar to a Lambda probe sensor, which may have been caused by problem number one, the ignition coil, cables, or even the spark plug, today I replaced them, and I reset the os Scanner errors, I also took advantage of it and removed it the day I replaced the ECU, and moved it from above the engine. Now I will observe, if it will continue to present any more errors. I'm going to check this connector D4, but the fuses I had already checked all. And about the oscillation error at idle, it still unfortunately continues, but to a lesser extent. Regarding the value of the car, I bought it for €900, I spent €140 on the suspension, €164 on electrical repair on the temperature fault, temperature sensor, changing the crankshaft sensor and changing the battery, €170 on the control unit and the reset hers and now €20 more in candles. Total €494, but these cars here are in the range of €1600 to €1900, and there's always something to fix.
