Year of Manufacture: 2014 Engine Size and Code: 166.824 ( Optional ) Scanner Used: Autel ( Optional) Fault Codes: 13DF00 20EB71
Two faults that are relevant. 13DF00 Adblue system faulty. 20EB71 Power supply at input of combustion ECM is faulty. Vehicle came in with a gearbox fault. The vehicle has suffered water ingress under the carpet. I have cleaned the connector that was affected and now have all gears ok. The vehicle was apparently showing the Adblue fault before the gearbox problem. I have checked all fuses except the ones by the battery as I haven't dug my way into them yet! My problem is what is the "combustion ECM"? is that the engine or the Adblue ECM. Struggling to find a way forward from here.
