ACC Calibration / Adaptive Cruise Control / Audi A4 A5 Q5 / Distronic / ACC Audi / ACC Skoda / ACC VW / ACC Seat
As per given instruction within the thread audi4ever forum I have built a “mirror” (about 1100mm x 800mm), from the reflection side I have attached two pieces of plain sheet metal which reflects the radar beam (76,5Ghz) in three different vertical positions:
Position 1 = 89° (inclined toward the car)
Position 2 = 90° (straight angle)
Position 3 = 91° (declined from the car)
In my case I have calculated that 1°shift can be achieved by move of the “mirror” support about 15mm towards front or backwards at the base of wooden plate, (no need of digital protractor).
„Mirror” has to placed perpendicular, central, 120cm from the radar:
Remove the radar from plastic supports and set all three…
