Does anyone have the wiring required to change the PDC module from a 3W0919283B with 2 connectors to a 3W0919283D with three connectors? The new module is coming with the three connectors removed from the car. I am guessing that I am not reinventing the wheel. IETIS is driving me nuts trying to get the info I need.

 

Hello @73Landau ,
Sorry that you are not having much luck with replies..

As to the 2 plugs versus 3 for the B to D, I have done it, but I hastily buttoned the boot all up before fully testing, so I will have to drop the NAIM for Bentley sub woofer box, the lower the shelf to redo some wiring.

Here is why, because we have all the pin outs as shown in ietis for the B version, the two plugs, one 20 pin and one 16 pin, we know that all power, switch control, and CAN BUS pins go to the 20 pin plug, and both the front and rear sensors go to the 16 pin plug, but on the D version, all power, switch control, and CAN BUS go to it's 16 pin plug, then the front and rear sensors are separated into each of the two 12 pin plugs that the D version has, the only problem is, that nowhere in IETIS does it show which 12 pin plug or socket of the D version is front or rear, nor does it show the connector view of either 12 pin connector, as it does for the B version's 20 and 16, so I feel that I must have lost on my 50/50 gamble on the 12 pin plugs, so I will have to drop everything again to gain access and repin each 12 pin plug, as they are not switchable, and if you are thinking that the wiring colors could have helped to match front or rear, my D version didn't come with the plugs, I purchased them separately, and they where from an Audi, so the wiring colors were totally different.
If you purchased plugs from a Bentley, please share pictures of said plugs.

My issue of failure is that I now have 8 fault codes for the PDC, and 9 exclamation symbols on the PDC display of Infotainment screen, all to do with the sensors, maybe I will get to it this week some time...


Below are pictures of my pin outs as per IETIS from the 2006 B version to the 2007 to 2011 D version/3 plug type.

Very sorry about my horrendous hand writing, it was written in the wee hours of the morning while working on it, I will rewrite it if necessary.

I doubt that all 10 sensors are defective, eventhough they are the original silver ones from Hurricane Sandy, as I recall the beeping tones coming from the front and rear with the B module installed, I do have a complete rear harness and 4 black sensors from the parts vehicle, maybe before I drop the shelf, I'll just plug the parts harness in and check for any change in display or fault codes, but, I am seriously thinking it is the wiring of both 12 pin connectors.

Thanks Johnny,
The unit that I have coming is from a Bentley with the 3 connectors and wires still attached. I will see if I can do a mud map of the connectors and colour codes when it arrives this week and post it up, Hopefully, it may help.
Cheers Greg
