Electrical malfunction of lights and hazards TDI MK6

took apart switch relay from engine fuse compartment, and it needed to be soildered. no more issues with lightt panel. I had placed An AGM dry cell battery and it over loaded a few fuses. so far so good with fix and replacements. EGT Sensor circuit one bank one also replaced, now clean ego valve and remove cat converter clean with detergent and reinstall. regeneration occurred with diesel particulate is completely clean. all tests with electrical and testing with Ohm tester are clear. new battery assisted. alternator still strong and working. MK^ still has issue with moisture in the cabin of car this is a noted issue but dehumidifier packs are helping and no more moldy leather seats. car will be going for a major detail and shampooing in spring. Canadian winters are hard. vehicle is kept in a dry heated garage.
