The process is, after having disconnecting the battery for a few minutes then reconnecting it, turn the ignition key to light up the dash (not turn on the engine) for 10 seconds then off for 5. (A proper 10 and 5) Repeat twice more (so you’ve done the sequence three times) then start the car. Keep your feet away from all pedals as you do it. Touch nothing but the ignition key, just to be certain. If you’ve done this properly and you still have the issue have you considered it might be a slight glitch in the ecu programming?Having it reflashed might be the next step.
