As I understand it they are looking for a 3mm fillet weld on the inner right hand face at the base of the brake pedal actuator arm. In some cases it is incomplete/insufficient, so should be relatively easy for your dealer to identify if you are affected. The dealer has a bulletin from MMC showing the correct position and extent of the weld.
Everyone always talks about "Their Dealer" yet in the USA Dealerships are few and very far between.
