Are you planning to tow a caravan with your X3?
Towbar fully electric 3AC £765
Beware It would appear that my new Rosslyn built X3 m sport with factory fitted towbar 3AC has been delivered to my dealer with a 13 pin socket on the swivelling towbar arm BUT all 13 pin functionality is NOT included Apparently supplies to pin 9 for the ATC and pin 10 for the Fridge/leisure battery charging are not there My dealer informed me yesterday that he has ordered the additional loom and will be fitting it today No idea of costing or who will end up paying. This is an old chestnut that BMW are refusing to rectify at the factory. Towbar fully electric seems to mean that it MOVES!! |

Being a loyal subject of the Crown I can translate. He wants to tow a trailer but the wiring loom on his South African built X3 won't power all the appliances in the trailer while towing.

Since 2009 all touring caravans in the UK have been supplied with 13 pin electrics wired up to a standard approved configuration. The blogs are awash since then with instances of BMW OEM wiring not matching this standard. It would appear that in my case BMW are still not fully wiring the towbar socket and this is having to be carried out at the dealership. My original post was a warning to future OEM towbar bloggers Thanks again PRAY FOR MOJO |

This has always been the case with most European cars. My last BMW had pins 10,,11 and 12 missing form the 13 pin socket as do all VW and Mercs with factory fitted towbars. Battery charging and powering fridges aren't a thing with German caravans.
My van is plugged in at home so the fridge is cold before I set off, we then put chilled food/beer in it and its still cold at the other end of the journey. Not really an issue for me although I have looked into wiring up the extra pins here. Can you do me a favour though when you pick your car up and ask them what loom they have ordered and fitted or if they had an auto electrician fit the extra cables? |

Yea...our family had a caravan when we lived in New Zealand in the 80s.
My dad towed it with his 81 Mazda 626. Picture an elephant attached to a tick. My point was that his random words made no sense without any context or understanding of whether he was asking a question, or stating a fact, or ?? Luckily you POMs (no disrespect, remembering the word from the NZ days and still think it is funny) were able to translate into proper English (ie American). Poke. Poke. Poke. Poke that Bear. Installing flame suit as I giggle to myself, stupidly. Paul |

I was merely pointing out to any bloggers in the UK that have ordered an X3 and have specced up the factory fitted towbar 3AC that it is unlikely to have full 13 pin functionality in the wiring . Hope this makes my original post clearer for you JEEPERS JOEY Thank goodness for PRAY FOR MOJO |

3AC towbar fully wired up
Apologies for digging up this old thread, but I was googling something and found this and can offer a solution to this problem.
I successfully managed to make all 13 pins on my 3AC towbar work correctly for a literally a few pence worth of BMW connectors as linked too by Dandle Here are links to how I did it. Pin 10 wiring https://forum.bmw5.co.uk/topic/14233...-installation/ I also used pin 12 to be a dedicated charging point for the car battery. Pin 12 wiring https://forum.bmw5.co.uk/topic/13757...ng-3ac-towbar/ My dad has G01 with the same issue, but my beer stays cold now. |

I found on the factory fitted electrical towbar all 13 pins were already populated on the G01. I think sometimes they don't code for the switched ignition to work though.

My replacement towbar had all 13 pins present, but pins 10-12 had no wiring to them, rather than coded out.
The lights are on but there is no one home. |

The wiring is all present on the G01 and the newest X5 as well. I suspect it's the same on all the electrical folding towbars now. They just don't code them to fully work.

Anyone who tows and uses the excellent MILENCO aero mirrors is strongly advised at least to change the pads to the Falcon type or alternatively fit the complete Falcon clamp as shown here:-
https://www.milenco.com/products/mir...-mirror-spares https://www.milenco.com/products/mirrors/falcon-mirrors I towed for the first time with our X3 last week with the standard aero mirrors and not only were they a bugger to fit but I was worried that one or both would end up spinning down the road behind me! |
