Hi, 

i have had a few BMW’s but I now have my first x5. Its an e53 2002 3litre petrol, manual. 

Anyway. Simple question about parking sensors.... as always, by sounds of it. 

Sorry if I need to post this somewhere else

 

the system doesnt beep when I reverse. It beeps for a few seconds when I engage reverse and the light on the centre console flashes. I have checked the sensors and they are all clicking, front and back. 

I have plugged in the obd scanner and no codes are thrown up, I cleared them anyway, but still nothing. 

Any ideas, and please feel free to move this post if needed.

thanks. 

Stu

Welcome to the forum 

The BMW parking sensor system fitted to cars of our vintage is flaky to say the least, yours is showing the classic signs of 1 or more sensors being dead. You can turn on the ignition select reverse then put your ear near each sensor you should hear a clicking, no click = sensor not working. If you also have front sensors don't ignore them 1 sensor out means no system.

Which code reader are you using? I use BMW 1.4.0 and I can read and test individual sensors I have a sensor that hates rain, car washes, jet washes and cold weather?? Warm dry weather all OK when I read the codes for the PDC unit it shows "rear centre left" I have changed the sensor no difference so I believe my fault is in the loom some where which with the current weather can wait as I have a reverse camera. Also I have a factory tow bar fitted when I plug in the horse trailer it turns off the rear sensors and the fronts work fine.

When buying your sensors make sure you get the right ones check the part number on www.realoem.com put the last 7 digits of your Vin in the search box and it will bring up your model.

Here is information on mine for what it is worth

Dave, 

thank you for your great reply. 

I am using a c110 scanner, it works wonders but I could do with the bmw one that everyone talks about... the 1.4.... 

mall the sensors are clicking and all sound the same, so I can’t seem to find the weak one. 

Ill get the other scanner and see what pops up. 

Thanks again!

It may be in the loom or it could be the PDC controller. Try unplugging the unit use some contact cleaner and reconnect. The PDC controller is buried in the boot so susceptible to any damp or spills.

Awesome! 
thanks for that, I’ll give it a go later

thanks Dave.
