front bumper sensors
Hi,
Can someone enlighten me on which sensors are associated with which system? There are 6 sensors, 4 external (you can see them in the bumper), two in front and one each on the sides. There are also 2 behind the bumper which cannot be seen. I'm under the impression that the 4 external are tied into the proximity warning lights on the dash and the 2 internal are associated with the distrronics system (cruise control). Can someone verify this? Reason being is that my left side indicator randomly activates to full when there is nothing near the car. Very annoying and unsafe. I did have the bumper painted (road rash) and MB will not warrant the system, they say the paint guys caused it. The paint shop is very willing to replace bad sensor. Paint shop is Stewarts in Dallas, the best around, authorized and recommended Porsche shop and always tons of Ferrari's being fixed. I just want to be sure the correct sensor(s) get replaced.
Thanks in advance.

The parking sensors are the 4 you can see. They are ultrasonic sensors and are calibrated for a specific thickness of paint, if they've been re-painted they often act up.
They also pick up weird reflections and go off at times for no good reason momentarily, so even a new sensor may not solve it 100%

as I understand it, the 2 in the grill and the 2 on the front of the bumper are for parking, the 2 on the outside of the bumper are for the parallel parking (same on rear bumper). They are for side pickup. . I would guess that they may be intermingled within the system so they could give multiple signals.
Anybody that replaces sensors go by part # , its not a guess as to what they are for
