I would change the brake lamp switch first at only £11

EPS?.. If ESP I've had that trio from 2 different causes.

1. dud wheel sensor.
2. very low battery (can also trip the autobox limp mode-won't change out of 2nd).

Not saying they're the answer but that's been my experience.

they can take a while to stop coming up, unless you have the codes cleared. it took about 3 months on mine. id decided i was going to tolerate it (wasnt an MOT failure point at the time) then one day i got it and it didnt bring up the warning any more!!!

As said above check you battery, if is not putting out more than 12.5 volts this can also cause the problem you have mentioned.

If you have had the battery off (assumign yes due to alt change) then move the steering wheel lock to lock to reset the ESP.
