ACC & Sensor Malfunction on 7.5 GTI
I recently swapped damaged plastic parts on my front bumper thus removed the front grill and unplugged the sensor cable.
After around 300ks my ACC stopped working saying "Front Sensor not available. No sensor sight." So no cruise control etc.
I've read horror stories of up to 500€ for calibration so I was wondering if there is another fix.
What I've done so far:
- Reseated grill and radar cable
- cleaned VW badge
- tried to erase fault codes (there were none surprisingly)
- cleaned sensor as such (still a little dusty, wouldn't use any liquids, maybe should (?)
I've had the typical errors in snow and ice but they went away every time.
Also:
I've seen people using obdeleven to recalibrate the sensor themselves 120cm in front of a wall. Is that feasible?
Thanks for you help in advance!
