I wonder how many write offs there have been?
A drowned BMW or similar "sophisticated" vehicle can easily yield catastrophic costs.
If the electronics fail, you have a serious problem. How many out of 100 control units are defective? And which ones?
The problem is that usually the OBD, the "door to the vehicle's electronics," is simply lost. What to do then? Even if you were to replace all 100 ECUs (which would probably already be an economic knockout), there would be no guarantee that you would get any response from the OBD. Wiring harnesses and connectors are soggy and also dirty. And changing a wiring harness may require disassembling half the car.
Feasible? Maybe. Affordable? Probably not. If the car was brand new, say 70,000 euros, it still had a value of maybe 60,000 euros before it went down. Replacing all the electronics could cost 30,000 to 40,000 euros - without any guarantee that it will still work afterwards. No dealer will take that risk.
At best, such a car will be traded in for a new car, with an estimated value of maybe 25-35 % of the normal market value. OK, optimistically, maybe 40% ... ?
So:
New car: 70'000 (cost)
40% for the 60'000 Euro value of the car that went down: 24'000 (proceeds)
Balance: 70'000 - 24'000 = 46'000 : this is the amount you would have to pay to restore the former status quo.
A loss of 46'000 euros (pounds, $, whatever) ...
Ok, you then have a new car, but the value immediately drops by 15% due to registration (based on German experience) - and you are back to where you were before - but you lost 46'000 Euro - not to forget your 'Alden' shoes for 1200 Euros, of course ...
That's just my idea of what such an idiotic idea can cost. I might be wrong on the details, maybe 15'000 euros more or less: in the grand scheme of things, I think that's the point. You can break it down to less expensive cars. But I have seen a lot of AUDI A6, BMW 5 series, Mercedes E-class ... ...
In the middle of the ford, at the latest at the end, the lights went out or started flashing in disco mode. When the cars were pulled out, the rear tires locked up because the electronic hand brakes went into safe mode (locked up) and the automatic transmissions didn't know what to do anymore - just to name a few problems.
