Bought 2009 Ml320 a few weeks ago, in the middle of DPF/SCR delete and found this plug...

Can you show more wiring harness routing, in other words, where does the harness lead?

Ok noticed a part number...



ran that number in EPC and got this

Went back and checked and it looks like someone deleted the heater element to the fuel filter...hmmm


Anyone have an idea why some would do this?

Maybe it was faulty and the previous owner didn't want to replace it?
