Westfalia ASTM 506633 Trailer Module

[Family Wagon 23]

Wondering if anyone has or knows where I can get a Westfalia ASTM + Buzzer 506633 Trailer Module in NZ? I found water in mine (no idea how it got in there...) and trailer lights power out has failed so expect I need to replace. 

I can only find them with full loom in Australia = $$$+ delivery time.

What car are you fitting it to?

I used this when I fitted the towbar to the E46.  It works well.  https://www.trademe.co.nz/motors/boats-marine/parts-accessories/trailer-parts/listing-3011392114.htm?rsqid=c96668a2e7f2402782e1a41d20d3aeb5-001

There is also one for Canbus systems. Don't know anything about it though. https://www.trademe.co.nz/a/motors/car-parts-accessories/other-accessories/listing/3009990178?bof=7u7c0lVl

Hey thanks for the assist. It's going into an E61 550i touring. 

The second link Can bus system looks like the same plug set out. I'll try giving them a call. 

I seem to recall the car being coded to it so suspected I need the exact Westfalia part but that's a long time ago since installed and hopefully these may be generic (fingers crossed).

I have a genuine Westfalia bar, and currently use the "TEB7AS" relay in the first link above on my e60 LCI sedan - quite easy to install, and no issues with the LED indicators etc. It doesn't however have the genuine BMW / Westfalia feature of disabling the PDC sensors when reversing, but a push of the PDC button inside the car silences that. I also don't think it gives you a dash warning to indicate if there's a bulb out on the trailer (I think the genuine ones do?), but there is a discrete audible tone from the module when indicating which will not sound if an indicator lamp is out.

Even with other brands of trailer controller, it should be possible to tell the car to disable the pdc (may still do it automatically) - my F31 has an Erich Jaeger CANBUS controller and it disables automatically. I don't think any other specific coding was required.
