As my 2016 is over 10 years since production, and nowadays the life of OEM electronics is somewhat not well documented - I'm curious how long we should expect the Denso (I'm an F type R) engine management systems, charging, hotel features (dash, audio, other electronics, etc.) to hold out.

I've clocked just over 31K miles on this car in it's life. I'd love to be able to rely on it for another 10 years. I have the electronics of the Ford version of the Bosch Motronics (EEC-IV - made by Ford? or Bosch under contract for Ford?) in my FFR Cobra Replica. Those parts were from my 1988 Mustang 5.0. It is essentially one ECM module, with a half a dozen sensors. It still works great to this day. The good thing is that I acquired a spare ECM that you simply plug in for a swap (I occasionally do that just to make sure that both still work). Unfortunately for our cars, that's not something you can easily do even if you had a 'spare' ECM.

With these cars, I'm not even sure I know the number of 'modules' (I would assume dozens), Canbus (made by whom?), etc. Artificial Ignorance says many Jag models use the Denso electronics (X300, X308, X100 (XK8/XKR), X-Type, S-Type, and early XF/XJ/XK, however it says the only other Jag models with Denso ECMs are the XF (2010-2015).

Has anyone done any research here? Any clue as to how long these can be reliable (i.e. not at the end of the bathtub curve Weibel chart)?

 

Automotive reliability standards target 15 years at zero failures. This is a target. There will obviously be failures.

A lot of it depends on the luck of the draw. 20 years is probably quite doable for many. Some poor soul is going to have a major failure at five years.

 

Are said 'standards' consistent amongst all manufacturers?

 

Well, they are ISO/AEC/IATF standards, so at that level, yes they are consistent. I'm familiar with them at the component level (spent time in the semiconductor industry). Obviously, as you combine components into modules and modules into assemblies and assemblies into parts and parts into cars, there are opportunities each step of the way to cut corners or just flat out make a mistake.
