Hi
so I replaced the ECU and FBCM as they were bad. The car works now but it has PASM alarm. My ca r never had this feature or module. it also has a lane change assist and air bag warning. Is there anyway to erase these modules? Thank you

Replacement module comes with default coding from the donor vehicle or from the factory. Default coding automatically enables features your Cayenne may not be equipped with. When the module thinks the vehicle should have PASM, Lane Assist, Rear Sensors, Air Suspension, etc., and it doesn’t see those modules on the CAN network, it throws faults. You can delete these systems out of the modules but you need to use the PIWIS II or PIWIS III (the correct factory tool). There is no other way to do this, they do have after market scanner like Autologic or Launch X431 with Porsche coding access but the access varies with no guaranty of it working.
