SITUATION
As a settlement to a class action lawsuit, BMW of North America agreed to update E60 (5 Series) vehicles produced up to March 31, 2005 with improved passenger recognition software, if specifically requested by the customer. The settlement includes all E60 vehicles with sport seats (option 481) or with multifunction seats (option 456), but without ventilated seats (option 453). Vehicles that have had the updated software installed during a prior repair, or have had a seat mat with the updated software installed during a prior repair, are excluded.
Customers of affected vehicles will be mailed a letter (see attachment) which provides details of the settlement and which explains what the customer should do if they want the improved software installed.
BMW authorizes the following repair only when requested by a customer with the above letter.
PROCEDURE
1. Confirm that a copy of the customer letter has been provided. If the customer is unable to provide a copy of the letter, send in a PuMA case to "Electrics/Electronics" for authorization to proceed with the repair. Mark the PuMA case B720207 in the subject line. A copy of the customer letter or PuMA case must be filed in the vehicle file.
2. Use special repair cable 52 1 010 to recode the OC3 seat occupancy mat (do not replace parts): Repair cable 52 1 010 was shipped to dealers under the Automatic Tool Shipment program.
NOTE: If the vehicle has a faulty OC3 mat (confirm by carrying out diagnosis and running the applicable test plan), replace the seat mat. Refer to repair instructions 52 13 400 (Replacing seat cover for left or right front seat (normal/semi-electric)). No further work is necessary.
