My detailed thread three years ago was about the 1213 switch for the ECU. Without +8Rich's advice, I would have continued to be blind and no idea about the switch existing. I had already changed the throttle, the MAF sensor, the ignition coils and the accelerator pedal😰😰😰 (ok, all to test with used parts, but I was desperate).... a whole year of unsuccessful trying in the dark and all without any hint from OBD2. My garage also had no clue.
The car stalled out of the blue and wouldn't pick up the throttle. It turned out that switch 1213 had a loose contact. This switch activates another control programme as long as you brake.
