Hi guys. I'm having an issue with my 560sl running warm or at least that is what the gauge is telling me. I think the coolant temp sensor may be bad. I was on the EPC and it looks like there is just the one “sender unit” with part number A 005 542 10 17 or A 005 542 26 17. Upon inspecting the car it looks like there is another sensor right next to what I believe is the CTS. This other sensor has 2 separate wires connecting to it. One wire connected to that sensor has 2 prongs and the other has 1. What sensor is this and what sensor is actually the coolant temp sensor? A part number would be great too if possible. Thanks in advance!
