One of our trade customers in Ipswich had a Mercedes S Class W221 with an ISM fault. They had purchased and fitted a second hand ISM unit but was unable to code as it was a used part We successfully unlocked the second hand part so it could be coded to the vehicle using Mercedes main dealer software. The unit was then adapted and tested
