Front PDC parking sensor sonar echo caused by grommet?
Problem
My F15 started to give me obstacle alerts from the Front Left PDC parking sensor when stopped at a light or just taking off.
Analysis
Having cleaned any dust or debris off the sonars, I noticed that the grommet surrounding the offending sensor is raised about 1/16" or 1mm compared to the other sensors where the grommet is almost flush.
Questions
- Has anyone had this grommet issue and confirmed that it is was causing the phantom sonar echo?
- Would this be covered by factory warranty or is it considered a maintenance item?
Thanks!
