Hello!This listing is for a W205 C-Class auxiliary battery control module. Really, it's just a voltage regulator that helps with stabilizing the alterator current to the vehicle, but when this part malfunctions you'll get an "AUX Battery Malfunction" message on your instrument cluster. Nearly all W205 cars don't have aux batteries, however. Replace this and the message will be gone. PLEASE PLEASE PLEASE if you are unsure of whether this fits your car, send me your vin number so I can verify fitment. Some W205 cars do have auxiliary batteries! Free and fast shipping from a Mercedes repair shop that's been working on these vehicles since 1985.
