PDC sensors?
 

So I found that the front corner (pass side) sensor on my ride is bad. Where does everyone get these sensors from? Dealer wants 140 bucks for one, I'll just drive without the PDC working before I'll pay that.

I got one from eBay for a lot less than that. one of my rear sensors is bad so I bought one.I, too, called in my BMW dealership and they said it would take minimum 2 hours labour plus price of hardware.....

I bought 2 sensors on ebay for 35 bucks, plugged them in and they work just fine. Took me 15 minutes to do both.

Dealer is right about the facelift sensors on the corners being a a pain, you have to drop the bumper most likely, and be aware they are the corner shaped sensor on the facelift (front corners only).

You need this, if you're handy you can get it done in an hour including dropping the bumper.

How do you find out which one is bad? I started having issues with my rear sensors

what i did was; put the car in reverse and pull the Ebrakes so it doesn't move or just have someone press on the brakes while it is in reverse, then listen to each sensor and if you hear a clicking / ticking sound, it's good. If not, that sensor has a problem.

could you just press the PDC button on the center console module (A169 module)?:dunno:

I just got this Wednesday. Works perfectly.

To find the bad one I scanned errors in BMW Scanner 1.40, it says which is bad.

ou, smart. I haven't checked it like that before, but I assume you can!
good thinkin':thumbup:

Yeah you could just hit the button to activate the system. Replacing the corner sensor is def DIY'able. I think there are a total of 10 bolts between 10 and 8 mm. Use a plastic putty knife to unclip the bumper at the fenders, pull it out then lift the cover off the front. Don't pull out too far because the leads on the sensors isnt very much and if you have Cold Weather Package, the headlamp washer hose is also cut very short. It's a pressure fitting with a retaining clip. Remove the clip and pull the coupling apart. If your washer rez is full, be sure to have a container to catch the washer fluid so you can replace it later.

Pop the sensor out, put the new one back in and smack it all back in. Your first time doing it will take about 1.5 hours... When you need to do it again, 15 mins.
