I made procedure: " Insert the key but do not turn. Fully depress the trip reset button and hold down. Next turn the key to the on position three times and then leave in the on position. Release trip reset button and the gauges will flicker and the odometer will count down and then show the trouble codes" First odometer showed 111111, then 222222 ....and finally 999999. After that odometer showed current trip distance and procedure was done. Does it mean - no errors in ECU?? If they are when they are show - after last 999999? Pawel
