:-[hi all.

When i bought my x5 the parking sensors were not working. So i had it put on the computer and code 18, voltage, converters in general.

So was told it was the PDC control module. After changing it for a working one i still get the original symptoms which are a loud constant tone and parking sensor button indicator flashing.

i'm located in west yorkshire.

Any ideas what it can be? Thanks in advance

before you changed the module did you make sure all the sensors on the car were "clicking"?.
I say this as im having a nightmare with my pdc's at the mo,
mine are all clicking as normal but I still get the beep and the flashing pdc switch...

No clicking. Just constant beep and light on pdc switch flashing. The sensors are not even being engaged it seems.

Check the connector in the rear of the vehicle under the boot floor,mines had a towbar fitted and someone didn't connect it back up and same as a friend of mines had same issue,the plug is under the floor to the r/hand side.

is that near the battery area? I suppose i can follow the connectors from the module which should lead me to this connector.

You dont have to remove the spare wheel just lift the boot floor and not far from the light cluster on the r/hand side,just about where the bumper bolts on.

so , if you put it in reverse , the sensors dont click?

no clicking when in reverse.  I have not had a chance to get as just on holiday.  Soon as i'm back i will have a look at it all.

Is that the connector? I can't see anything that connects to it?

That's the connecter for the towbar electrics if it's in the boot under the spare and the air suspension compressor. There is a dedicated towbar electrics mobile you can purchase which integrates the towing electrics with the cars electrics so no wire cutting and splicing needed.

no thats not it,the one you are after is in the corner under the light cluster.

Just checked the plug and it seems fine. The wires all look ok too. Anything else I can try?  :blink:

Sounds to me like you have at least one faulty sensor

Get yourself an cable and a copy of inpa. Then you will be able to see exactly what's going on with graphical representation of the sensor outputs. Diagnosed mine in two minutes.
