ESP and ABS lights on, & Hill Start Assist not working.

[anotherbob]

On my 2012 For Two Cabrio (84) the ESP and ABS lights are not going off, and the Hill Start Assist is not working. Any ideas where the problem is (I don't have a fault reader)

With a 450, your symptoms usually mean a jiggered brake switch. Noticeably, the ESP, ABS lights only come on after first application of the brake pedal. 451s may or may not be similar.

With a 450, .

The car is 2012 so will be a 451 😉 ..... but do agree with what you say. My guess was an ABS sensor

You were correct. Fault code says ABS sensor faulty. Getting it replaced today.
