2012 C300 Battery Draining
Hello All:
For the past several months, my 2012 C300 (w204) has been draining the battery when sitting for more than a couple of days. Figuring I had some kind of phantom draw, I tested each circuit and all was well. However, I have noticed that one of the relays in the engine compartment fuse box randomly clicks (with everything turned off.) The relay diagram indicates "Engine Circuit 87 Relay".
Is this normal? Could it be draining my battery? Appreciate any insight to help solve this problem!
