B1204192020-02-18. Service bulletin. ENGINE AND ENGINE COOLING. DME FAULT MEMORY ENTRY FOR THE CRANKSHAFT SENSOR: This Service Information Bulletin (Revision 1) replaces SI B12 04 19 dated February 2019. Technicians may notice this fault logged during a diagnostic session: Fault code: Control module: Fault Text: 160021 DME Crankshaft sensor: general loss of synchronism Environmental conditions are vehicle speed 0 (stationary) and engine speed less than 1500 rpm. There is no customer-facing symptom nor related check control message displayed. Phantom/pseudo fault due to unsuitable DME software. Background: After parking the vehicle and turning off the engine both DME control units go into sleep mode at different times. The DME of cylinder bank 2 ("secondary") goes into sleep mode first The DME of cylinder bank 1 ("primary") is still awake and can experience a reduction in signal voltage for the crankshaft sensor signal This signal change can mistakenly be evaluated as a skipped crankshaft sensor cog by the DME. If the engine is started while the primary DME is still awake this causes a brief loss of synchronization with the secondary DME. Fault 160021 is logged after three (3) consecutive engine starts with this momentary loss of synchronization. Note: Starting the engine after the primary DME has also gone into sleep mode will avoid the loss of synchronization.
B6210192020-01-21. Service bulletin. SERVICE BRAKES. INCORRECT CONDITION BASED SERVICE DATA FOR BRAKE FLUID SERVICE. "Brake fluid service due since 12/2001" is displayed in the instrument cluster although the vehicle is only a maximum of 1 year old. Software error in the KOMBI (Instrument Cluster).

B3303192020-01-21. Service bulletin. SUSPENSION. SERVICE ACTION: CHECKING THE THRUST WASHER AND THE REAR AXLE ANTI-ROLL BAR. On vehicles with an incorrect setting of the thrust washer contact between the thrust washer and the sway bar may occur over time. This can lead to corrosion and breakage of the anti-roll bar. Installation error of the right side rear axle thrust washer during manufacturing.
