Kalibracja radaru, ustawienie głowicy ACC w Audi S6 C7

Adaptive cruise control radars sometimes require calibration. After bumper removal, alignment adjustment, suspension replacement, or after a collision, the system requires calibration for error-free operation. If the front ACC radars are not properly adjusted, the message "ACC system and Audi Braking Guard: unavailable" will be displayed (or an error message about ACC, Front Assist, Traffic Jam Assist, Lane Assist), and error code C1103 will appear in the radar control unit 0x13 or 0x8B. Radar calibration will cost several hundred zlotys at a repair shop, but fortunately, it can be done yourself without an expensive calibration board. In this video, I show how to revive the ACC system in an Audi S6 C7. ℹ️ In this car, the front bumper had to be removed during engine service. After reinstalling it, the ACC system did not work, and error code B2005 - data record invalid - appeared in the control unit 0x13. When the radar is disconnected from the vehicle for too long, it can "lose" its parameterization and "don't know" which bumper it's mounted in (standard, S-Line, S6, RS6). Using the VCP program, the parameterization was reloaded. ℹ️ The system started working, but after a few minutes of driving, another error appeared: C1108 F0 - Adaptive cruise control sensor - Restricted View. We examined the radar itself and found that the lower mounting pin was loose, the radar was wobbling up and down, and sometimes pointed upwards at the bumper, causing it to report a poor visibility error. I pressed it in, it clicked into place, the error cleared, and the system is working again. ℹ️ After a few hundred kilometers, error C1103 00 - Adaptive Cruise Control Sensor - misadjusted appeared in module 0x13. In module 0x8B, however, error U1113 00 - Function limitation due to received malfunction value. This means that the right radar is incorrectly positioned and requires calibration, and the left radar is inoperative because the right one is inoperative. ℹ️ Fortunately, this car has an older type of radar, which is adjusted with two screws. So, if you have a 3.5mm socket and know which screw to turn in which direction, you can perform the calibration yourself. For both modules 0x13 and 0x8B, access the live data and check the values ​​displayed for the Misalignment Angle. This is the radar's misalignment relative to its ideal position. The tolerance is -0.8 to 0.8 degrees. Module 0x13 (the right radar) displayed a value of -1.36 degrees. Negative values ​​indicate a deviation to the right, which requires a correction to the left. 🛠 I removed the radar cover, marked the screw with a white marker, and turned it half a turn clockwise. Then, using OBDeleven, I connected to module 0x13, entered the security access code: 91153, entered the basic settings, and performed "Reset misalignment angle for sensors." I then cleared the errors from modules 0x13 and 0x8B and took the car for a test drive. 🔍 After a few kilometers, I read the radar misalignment again. The value was within tolerance but close to the limit, so I did another half turn and took it for another test drive. In a few hundred kilometers, I'll read the value again and try to get it as close to zero as possible. 💲 The service center calibrates the radar with the vehicle stationary and the calibration target. This requires considerable precision and proper preparation of the vehicle and tools. This takes a lot of time, and therefore will be expensive. 🚗 The same procedure should work for other VAG group cars (VW, Audi, Seat, Skoda) with single radar and dual radar systems.
