Frequently asked
Is code 29E2 safe to clear?
Clearing is only safe once you have read and recorded the freeze frame. Re-appearing after a clear is the useful signal; clearing without recording destroys it.
Is 29E2 a BMW-specific or a generic code?
This is a BMW manufacturer hex code. A generic OBD-II tool will not show it — you need BMW-protocol access over K+DCAN or ENET/DoIP.
