I have a weird issue in my 07 D40 2.5tdi. My dash lights, headlights,taillights,parkers turn on, wipers dont work, indicators flash but not on the dash or make noise,abs and parkbrake light sometimes comes on/flickers while driving. no codes come up when i scan it. leads me to think i may have a faulty IPDM (hidden fuse box). I have checked all fuses in all 4 fuse locations and swaped out the ECM relay inside the IPDM and still have same issue. I have also cleaned the earth from battery to vehicle. Can someone tell me where the earth is located for the ECM under dash. attached is a video while i was driving.
