Hi why not try paintless dent removal if they only need pushing out, these people do an excellent job for about £50 per dent I have used my local one a few times he is an Indian chap known as Singh the Ding.

Steering wheel full lock left ,then full lock right,then drive straight and that usually clears it,by doing the initial work on the car sometimes a host of lights are thrown up,have they tried just deleting the fault???
