Get to your PDC unit (water issue)

Post by Lee_2f2f » Sat Jan 01, 2011 3:16 pm

Right, a few people have mentioned of a problem with 'Xmas tree dash', random electrical issues, or their PDC (Parking Distance Control) showing special Icon showing up on your dash when put in reverse, like this:-

Image

The possible cause is that there is water in the PDC holster well & it has got water damage.

This can be caused by:

Changing your rear lights. (Reusing a seal instead of a new one on the lights)

Holes in the side of the car letting water in. (black things which have filters in for air feed inside the car)

If you have this issue, here is a Brief "How To" get to the PDC Module and check for water:

First of all, start by removing the floor carpet which basically lifts and pulls out like so:
Image

Next is to remove the plastic boot strip, located either side is 2 plastic Caps which you can remove with a flat-head screwdriver like so:
Image
Under these caps consists of a Philips Screw.... You know what to do.

Once you have removed the Screws if you look at the bottom of the plastic panel there are 2 plugs, simply Prise them out with a flat-head screwdriver like so:
Image
Then using some pin-nose pliers or another tool, simply pull. They are not attached; they are just plugs to secure it. Like so:
Image
Your side panel will then be accessible more easily like this.
Image

Next is to undo the bolt on the side which attaches some Trim to the hook:
Image
It requires a Torx Screwdriver, but I simply found a long enough Flat-Head screw driver useful.

For more ease you need to remove the plastic panel above which holds your rear speaker in place, I however left it there because it is very fiddly to remove.

I also recommend removing the rear light for more accessibility into the PDC's well.

Now that you remove all the nessicery parts, Simply Pull on the Arch cover, pulling it out from the boot seal and out as far as it will go (don’t bend it too much, it is fiberglass.)

The PDC is located down here:
Image

Now..... Model of your car MAY differ; I noticed some of you do not have the Polystyrene Holster for your PDC Module, whereas I do:

Example pictures here:

2009 FL 3-door M-sport Hatchback:
Image
Remy's Pre-FL 5-door M-Sport Hatchback (Notice the water issue she has)
Image

To remove the PDC:

For anybody with a PDC holster like Remy's simply pull the tabs apart either side and pull the PDC out.

For people who have the PDC like mine, the Wire is tacked to the polystyrene, simply Pull on the wire, and then slide the PDC Module out, leaving you with this:
Image

Now if there is water damage, and water in the well, GET IT OUT!!!

Disconnect it, get it in a bag of rice, and leave it in a warm location for 72 Hours (3 days)

Hope this helps you all.

Lee. :D

That is exactly what I think which is why I took the chance and took mine apart to make a "How To" and to check my own car for this common problem.

How old are both your 1ers Greame?

your two should be the same as mine then with the Polysterene then Greame.
my mate who works for BMW said that anything after 56 the problem was supposibly rectified.

Keyword here Possibly, so still check, but you can confirm when you check them. :)

This should be "stickied"
I never wanted to believe that my Dad was stealing from his job as a road worker. But when I got home, all the signs were there.

Hi All,

Please can you help. Need to get my PDC thingy out. Have managed to get to it with the help of this guide (many thanks) but can't seem to disconnect the unit from the connector thingies. How do i do that? Is it brute force or are there clips holding the connectors in? It looks like there may be but i'm too stupid to figure it out.

Please tell me how to disconnect the connector thingies safely.

Do i need to disconnect the battery first?

Thanks all, and hi.

THey are clipped in, you slide the clip off and then brute force to pull.
