Car D.I.Y.

[CXRAndy]

Its Stellantis, Mercedes, kia, Nissan and even Volvo that are requesting subscription from independent mechanics to access their advance feature systems. It goes against right to repair by locking down certain service functions.

They call it secure gateway access. OBD2 is still open and you can mostly read data and fault codes. The manufacturers are locking service features, like reset, calibration of modules etc

The problem BMW found was that because OBDII is so wide-open any Tom, Dick or Harry with a ZX81 and some time could easily crack it and then switch on any subscription functions for pennies in the pound. It became so widespread so quickly it wasn't financially worth carrying on any more so they binned it.

They shouldn't be locking any service, calibration or configuration-of-component functions, thats against the regs. Ceretainly with my VW and Volvo kit I can calibrate and configure any component, sensor or module. The only thing I can't do is software upgrades because it's proprietory and they charge for the actual download, but my kit is capable of it for those that choose to subscribe (a day's subscrption is usually less expensive than sending it to the dealer to be done.)
