Dismantling of the gear shifter was done according to the pics you posted. Got to tell you it was quite a job and itís really admirable that you did it again just to post the pics.
I donít know much about cars which means all I understood from you was that the ecu has a problem. Will it help to change it? Are we talking about computer reset or am I in for a hardware problem. How do I minimize the cost of the repair
