Cruise control retrofit

Hey there,
I have some questions about retrofitting cruise control on my 2006 Bmw Z4 2.5si.
1. Can I just plug in the stalk after I remove the panel under the steering wheel? Or do I need to do some wiring?
2. Can I get it to work after the install or do I need to get the coding done for it to work?

Hello and welcome!

You have a 2006 so the wiring will not be fitted. You will have to retrofit the cabling for it to work.

Not too sure about this, I would have thought it should work straight away but it probably won't (why would BMW make it easy) so keep in mind you'll probably need to code it.

It doesn’t need coding. You need to install the loom - try BMW or forum member srhutch who does a custom cruise control loom for very reasonable money. And you need to cut out the template from the lower cowl (it’s marked on the inside). Then it’s plug and play.

Good to know

I just checked out a video where they install the cruise control on a 2007 Z4 e85 and it seems to be harder than I thought. They had to cut some cables and connect wires to the cars main computer. Also run wires trough the dashboard. Seemed way harder than what I did when I installed a new radio in my car. I guess it's not different for the 2006 model. Might just leave it the way it is, because it's not the most annoying thing to deal with.

It’s not difficult, no cutting wires that I recall. The srhutch loom is tailored and fitting is simpler than the bmw one. It’s maybe an hour’s job and no particular competence is required apart from being able to follow instructions.

I did this job a month or so back. Srhutch ‘s loom and instructions were perfect and dead simple to follow - even for me

there is one cable goes through into the engine bay, but the instructions even told you what route to follow.
Just got to remember to use the cruise now !

I think you can still get the stalk from BMW but it's about £180 now.

But they do come up for sale now and again from breakers.

The good news is your 2003 car should have the wiring in place already.

New they are about £250‐£330 from a BMW dealership. Second hand about £100‐£150 when possible to find them as they don't come up very often.

If you have relatives/friends living in Germany who can buy for you then you can get a new one from here for £150:
