992.2 is standard equioed with start&stop, speed limit warning and lane keeping asist.even if I deactivate these systems, at the next startup they are reactivated again. I would like someone to help me find a place to modify my car's software in such a way that these systems, once removed, remain removed

 

it sounds like your car's systems keep reactivating. Maybe you could check with a car software specialist to help you modify it permanently.
