Re: Simple Solution

A mate has a new Audi. An option he was offered at purchase was a "security upgrade". This consists of a diode inserted in the command feed from the security ECU to the main ECU which prevents the former sending instructions to the latter and stops spurious commands from the outside world having access to the brains of the outfit.

He took it and still wonders why it's not standard.

So, we already have a situation where the various bits are separate (even my ten year old car has three ECUs, main/engine management, body control and security). All that's missing is the somewhat essential logic that prevents the bit that has its ears out in the ether reprogramming the other bits.
