It's no secret that the ability to change the default configuration allows the owner to set things up differently than he normally could.
Everyone knows that some are legal, others are not.
I will probably buy a Carli or something similar. But not because I necessarily want to change anything. Perhaps I will, perhaps I won't. But following Christian from LR Time, it's clear that a device to detect sensor problems, fault codes (which can block some functions until cleared) and information in general can massively help detect simple problems - like loose plugs, broken wires and the like, not to mention sensors that can often be replaced by tech-minded owners without risk.
Without an OBD device to "look inside" a car's electronics, you always have to go to a professional repair shop for even minor problems, often paying a few hundred bucks extra for something you could do yourself without risk.
And you need something that not only allows you to monitor the car, but also to program it, for example to clear a fault code that needs to be reset in order for a new sensor to be accepted by the system.
You don't have to be in a desert to consider buying such a device. It's an every day tool, a must have for the tech-minded owner of such a complex thing like a modern car.

... but anyway when you are 66 and the two dealer guys in charge of the Grenadier are around 45 and 30 ... two younger guys against an elder one, better run away than risk a fight
