Customer had advised us of the feedback he received prior to posting this review. As explained to him at the time, the technician based his assessment on the recommended procedure for removing the part in question that we had previously suggested be replaced before the vehicle was purchased. To our technician it appeared the work was not completed as parts involved in the repair still had factory markings on them. We suggested the customer return to where he bought the vehicle for replacement, we would not have made any money on the repair. Instead the customer went to another shop as he explains. We have tried multiple times to contact the customer since he published this review to no avail. There may be another aprroach to removing the part in question, we don't deny that, it is not the published recommended Porsche method. We hope all works out well for the customer.
