Has anyone been able to get the front tear drop wipe to work on an A4 B7 with Rain/Light sensors. I changed the coding as per below. My coding was 114 but the VCDS wiki says it should be 115??Channel 013: Wiper SetupStandard: 115+001 = Speed Reset+002 = Short to Plus Monitoring+004 = Rain Sensor active+008 = Long Post Wiping after Washing (Drop/Tear Wiping)+016 = Speed dependent Wiper interval active+032 = Headlight Washer System active+064 = Reverse Gear Wiping activeAny idea's why I cant get the tear drop wipe to work? I changed the coding to 122 and 123 but neither of these worked. TIA
