Hi All, I have been getting the P2407 error on my 2018 Discovery Sport. From what I research it could just be a loose gas cap. But it could be more. I've erased the code a few months ago and it just popped up again so I'm either really bad at putting my gas cap on or it's more.
Here's what google says "Evaporative Emission System Leak Detection Pump Sense Circuit Intermittent/Erratic," usually caused by a faulty Diagnostic Module Tank Leakage (DMTL) pump, a loose gas cap, or damaged EVAP wiring. A common fix for Land Rover involves replacing the DMTL pump and installing a protective cover.

So I don' t have a local mechanic and I my dealership is quite a far drive. Is this something I could fix myself?
