Unhappy Rear Parking Sensor Not Working, How do I replace it?

Hi,
I have a problem with the parking sensor over the exhaust pipe by putting the car in reverse and then putting my finger over each of the sensors in the bumper where it's easy to spot the dodgy one.

I believe you can easily purchase a replacement sensor on EBAY or other similar sites, but I'm not sure how you actually get access to the broken sensor that is located in the bumpers trim?

Can somebody please explain whats the easiest way to replace a parking sensor without the need to dismantle the bumper.

Hi,

I'd like to make a small modification to the problem description above. It should have read as follows:

Hi,

I found the problematic sensor by doing the following procedure:

First turn on the ignition, then shift into reverse gear (engine off)
Then put you finger on rear sensors you should be able to feel a pulse and hear a ticking from the sensors if you dont then you need to replace that sensor.

Parking Sensors

I also have a problem with one parking sensor on a 2004 320d. Does anyone know how to remove the old sensor and replace with a new one?

Cheers Lads, just confirmed one sensor u/s on my car. You're right, you can hear them tick, found the u/s one was silent. Cheers!

Park sensor.pdf

Hopefully I've attached that PDF correctly, shows how to remove the sensors.

After trawling through a lot of threads,could not find a definitive answer to the sensor problem ie;clicking=working,not clicking=not working,I found that one of my sensors was clicking slightly quieter than the other 3. I obtained a replacement from a breaker and bingo,job done,I reckon that if you get a good sensor and use process of elimination you should come up trumps.

Take the pumper off and unplug the sensor.

Parking sensor

I am not sure what is wrong with my sensors, they all click but it still doesn't work. I think it may be surface damage on the middle two.

Either way... BMW list price is 97, ebay second hand is 20 or (and better) original Bosch Sensor is 30 from Central Auto Supplies here in UK.
