Got to wonder about the cost of ownership for many of the current up market cars. The amount of electronics, proprietary software/hardware, cost of replacement parts, difficult to not user serviceable parts and systems make long term ownership a growing difficulty.
When black boxes in the up market vehicles cost a few thousand to replace, major mechanical systems costing much the same or more, diagnosing electronic problems not viable by the owner without brand specific software/hardware and more.. it makes long term ownership of these vehicles difficult as time passes. I'm of the opinion that the majority of new cars are designed and built to be in service for a short time past the warranty period. Once the warranty is done, the owner is expected to purchase/lease another new vehicle.
Co-worker had a Volvo that required a new engine.. it got that, then a front brake hose burst, then the CV joints failed, the straw that broke the owners back was a major wiring harness failure.. It completely shorted out.
I'm not convinced spending more money on a vehicle designed and built to last a specific service life makes reasonable economic sense.
I'll continue with older, less complex vehicles that can be maintained without being forced to the dealership for electronic diagnostic servicing.
Just think about the cost of wireless keys common to many cars today that cost hundreds to thousands of USD to replace or purchasing a spare...
Then we have throttle by wire, brake by wire, steer by wire and more.. It is all moving towards driver-less cars in the not too distant future.

Wow, what a bummer. I'm sorry to hear about your S4. My son owns one as well and I told him to buy a more practical and less expensive to service car so he can use the Audi for a pleasure car instead of everyday. Good luck !
