Jon, Chad and the team had replaced the 4 ignition coils on our '07 Mini, along with the routine oil/filter change, etc. Engine began to run rough with check engine light (yellow). After some in-depth detective work (5 test drives to ascertain), they found that one (1) of the coils had failed (under warranty). Replaced with no charge for parts or labor. I will always use Beckley for our Mini and our Volvo.
