This used OEM Upper Antenna Booster (4M8035225B) comes from a late-model Audi, salvaged for parts. It mounts at the left rear roof area to amplify radio, satellite, and telematics signals. When the booster fails, common symptoms include weak or intermittent AM/FM reception, loss of GPS or SiriusXM, and link errors for emergency call systems. It's designed for Audi Q8, RS Q8, and SQ8 with turbocharged 3.0L or 4.0L MHEV/PHEV engines.
