Towing - Everything that's required

[Entropy]

EDIT: I would like to make this a "sticky"-like post that contains everything required for setting up an E70 to tow. I will be updating this post as new information flows in from other members.


So I am finally getting my E70 ready for towing. I've read countless threads about towing and what's required, but I just wanted to summarize and verify with the resident towing experts.

What I know for sure is required:
- Trailer Hitch Receiver: BMW Part No. 71600440592 (I decided to go with Curt Hitch #13077)
- Wiring Harness & Module: BMW Part No. 71602156526 (note you can buy the Trailer Hitch Receiver and Wiring Kit as a package with BMW Part No. 71602156525)
- Coding: Can this be done with the Carly adapter? Also, does someone have a list of exactly what needs to be coded to each module?

What I'm unsure about:
- Trailer Brakes: Is a trailer brake controller required? Will electronic trailer brakes work without a separate controller using the parts listed above? Heaviest thing I'll be towing is a car trailer and car for 20 miles or so.

Thanks everyone.

Subbed. I've had the hitch and the harness in my garage for months.

Wiring kit purchased. Into it $390 now. It's my understanding that the wiring kit (part no. 71602156526) comes with the towing module, correct?

Also, I will be continually updating the original post with information to make it easier for others to gather information about towing with an E70.

Yes, the module comes with the wiring kit. I used a Prodigy RF (wireless) electric brake controller. However, you will have to use an alternate vehicle to pair the brake controller initially.

Where I live, it is basically a 3000lbs(1400kg) limit for towing without trailer brakes. I only tow a few motorcycles in a 12" enclosed, so am well under that limit.

However, I do intend on adding a trailer brake and going with the Prodigy RF.

Having said this, my e70 tows my bikes and trailer effortlessly.

This information is readily available on the forum if you search.

You'll need a controller to pull a loaded car trailer. I'd recommend hard wiring one. It isn't that difficult, it's pretty cheap, and you won't be messing around with a wireless one when you need it. I put mine by the obd port and it's out of the way.
