Hello Everyone. I have a real stumper. I have a 2009 335I. MSD81 and CAS3+ all keys are lost. Long story short is I need to read the DME ISN to make a new key with Tango. However when trying to read the DME ISN on the bench I get an error message stating to update the DME software. Here's the real problem, I cant update the DME software because I cant power up the car because the key is lost. I cant make a key because I cant read the DME ISN. Any suggestions?
