Hello 

Directly into question but situation first. I am not good at English I believe and I am sorry for that.. I am from Turkey and Turkish government/traffic regulations make citizens pay good money to only company to inspect their vehicles to prove it fits traffic regualtions every 2 years. It is ok but.. Recently 2017 I was having Ford Explorer 95 AWD(not switchable) Eddie Bauer 5liter which I brought to this inspection. They did a break system check on roller when rear wheels are on ground first and then they did it front wheels on ground.(they should do all wheels on roller). Yes I heard the waving noice like woommm and sound like something hit the ground. Eventually, I was hearing the crunchy noises and stepping/jumping sound and feel at the end, if I hit the gas pedal hard. As I understood it was about the transfer box and vicious coupling(cracked because of heat of oil pressure in between plates). I found the experts (university doctors of mechanical science agreed with my readings about the vehicle)and sued the company for faulty inspection service.

Inspection company did not agree with experts on court and they said that "those vehicles can understand and disable transfer box automatically to keep away the posibility of harm."

My argument is that "I don't know the situation on road which can make vehicle's only front or rear wheels stall steady other than slide. 4by4 mechanism tries to make them rotate to all wheels same way at same speed."

As their defence, they changed the policy of inspection of all 4by4 vehicles. If it is AWD, they are believing that it can't be harmed because of the electronics or mechanical automation.

 I won the case on court but they escalated to higher court to avoid paying my loss. Still continues.

Anyway the Question is;

"is there any posibility that newer technology can understand difference between servicing or sliding?"

Thanks in advance.
