My car has had an aftermarket shark fin dab aerial installed by the previous owner. The aerial seems to work fine however I'm getting these two fault codes on VCDS under the radio section.
2 Faults Found:
00856 - Radio Antenna
011 - Open Circuit
00821 - Antenna 2 for Radio (R93)
011 - Open Circuit
I'm guessing this is due to the built in diversity aerials no longer being used? If so is there anyway to disable the aerial in VCDS?
