Yeah, but the difference is, you had to. Now they hardly ever go wrong. Seems like progress to me...
(Tho' I would qualify that by saying I'm pleased neither of my vehicles have any kind of 'black box' in them - the moment you put a silicon chip in a vehicle, anything that does go wrong gets very expensive very quickly.)
Pros & Cons, as I see it
We don't really have mechanics anymore (yes, a generalisation, I know), as most items are sealed for life, & simply exchanged, not taken apart and repaired
Electronics aid better monitoring, & when the Lap-Top is plugged in to interrogate the ECUs, it can state where the fault is. No more 'trying to fault-find'/'back-track' to find the problem
Some items, that are electronic are silly, using my Octavia as an example for one which is VERY annoying;
- only the off-side rear fog-light is activated. it's a 21watt bulb that doubles as a tail-light, by means of running a reduced voltage through it
However, UK model ECU's do not allow the near-side fog-light to be activated, that's not right in my view
Towing lighting; for years & years, it was just spliced into the rear lighting of the vehicle, with an audible (or visual) warning for the trailer indicators
Nowadays, with all the CAn-Bus & multiplexed wiring, it's got to (generally) be a specific kit, & activated via TestBook (or whatever system)
Another one, that used to wind me up
Land Rover, when they went to electronic control/monitoring on the Td5 Defender, where did the place the (not very well sealed) ECU???
Under the drivers seat, with all the holes still unsealed in the seat-box, & this for a vehicle that was expected to be out in all conditions!!!
Granted it worked, & was reliable, but a fair few were removed onto the bulkhead (if a 90, or a Had-Top 110)
