Test the DEF heater and level sensors befor lowering it down
Hi guys, For, 2014ML350 Bluetec, just wondering whether it is possible to measure the ohms of the DEF tank heater and level sensors, before making a decision of whether to lower the tank down or not. It is noticed that there are 3 wires for heater connector A and 4 wires for Connector B. However, with all other wires coming together to reach the two connecting sockets right behind the RR shield, there are so many wires there and hard to identify. Is there a wire diagram to help with this? Thanks for any comments.
I would like to disconnect the DEF tank electronically, the fuse box under the right rear passenger seat is here attached. try to clean the connections. May some folks help identify which one(s) is(are) for DEF TANK? Thanks a lot!
