I'm not suggesting they will or won't make the car but ELL OH FUCKING ELL.
Hundreds of millions in R&D is spent every year by.. well.. every giant corporation.
I'm not sure if it works yet. My car is missing some pieces, so I've got to wait. It'll definitely be tested at Atco next week. I'd assume that it does, but they didn't give me a strong indication yet.
All flashes are easily detected by the dealer. The Bosch ECUs keep flash_count in their memory.
* from factory -> flash_count = 1 (original firmware write)
* flash BM3 once -> flash_count = 2
* flash back to stock & relock -> flash_count = 3
@razorlab is 100% right. If you think they can't...
