Service bulletin B651820

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

B6113052020-11-16. Service bulletin. Discharged Battery Energy Diagnosis Must Be Performed: The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle "discharged battery" complaints. In order to properly repair the vehicle the first time in the workshop, it is very important that the diagnostic test plans are performed to completion, with all results taken into consideration. Without performing the energy diagnosis test plan, the root cause of the discharged battery cannot be identified. This increases the chances of a repeat repair.

1209132018-12-03. Service bulletin. State Inspection and Emission (I/M) Test Fails Due To an Invalid VIN Number. The customer of an affected vehicle may fail to pass an I/M test due to a non-compliant 17digit vehicle identification number (VIN) stored in the DME (Digital Motor Electronic). The VIN read out and displayed on the state test printout does not match the actual VIN of the vehicle. If the DME was reprogrammed using the previously available BMW service equipment (e.g., Progman, GT1), it is possible that only the last 7 digits of the VIN were entered into the DME, and positions 4 through10 may only contain default characters. For example: The state I/M tester or OBD scan tool may read out WBAAA00000A123456 instead of the correct full 17-digit VIN, WBAZZ03492A123456.
