Post 04 cruise control retrofit N52

Ordered the kit last week and fitted it this afternoon - total cost £100. Took about 3 hours and relatively simple to do (with just a bit of head scratching to find the route into the engine bay).

Anyone else looking to fit this to their E86 there is an identical kit up on ebay now from the same seller: http://r.ebay.com/6vfo2a

I'm happy to help fit for anyone in the Northampton (weekend) or Notttingham (weekday) area. Just give me a shout.

I did the Cruise Control on my coupe over the last three days (between rain showers). I couldn't have done it using just the BMW instructions, but all the help here in the forum made it easy

Done this weekend (and last) to my August 2007 2.5i SE.

Lessons to pass on:

1) Read this thread ;-)
2) I ran the cable one weekend, and then did the plugging in the next. Purely personal preference
3) You need to run the blue cable into the smaller black electrics box just forward of the main electrics box under the bonnet. Some threads say you plug in in the main electrics box. I didn't. Take your time when feeding the cable through the trunking. I found taking the trunking out of its rubber 'boots' made life a whole lot easier.
4) Don't use the blue repair cable OR the black repair cable. Plug the blue cable straight into the mythical plug 39 in the DME box. Some instructions (German ones - see point 10) say use the black one on N52 engines, while some say use the blue one on N52 engines. Just don't use either ;-)
5) When you get the fat cable out from behind the headlight/fog light switch, cut the top-most cable tie, remove the steering column cowl (if not already off) and feed it down through there. I found the cable wasn't long enough to work with poking out of the headlight/fog light hole
6) The brown and blue pin blocks come out of the X12 cable plug thing. At first look I didn't realise this and took a while scratching my head ;-)
7) When you cut the yellow/violet cable, don't cut it too close to the plug, or it will be a pain in the arse to get back into the X12 cable plug thingy.
8 ) Some plastic trim removal tools make the job a lot friendlier...as does copious amounts of tea.
9) When I took the aluminium trim off around the headlight/foglight switch, the clamps (part # 07147073406) - number 4 on here leapt off and ran away behind the dashboard. I can't find them. Hopefully they won't be an irritating rattle from now on...
10) German instructions which confirm that it is pin 39 are here

Hopefully this will help someone one day

Does anyone know the current price for the stalk and loom from Sopers? I really must get around to doing this.

£105 for the stalk and £26 for the loom

Thank you Sir

Hi guys !
In need of a bit of help, I convinced the Parts guy down and BMW to print me off the retrofit instructions for the cruise control. I followed the instructions to the best of my ability and I have triple checked wires that i have spliced into ( using the pin numbers ) but i have ran into two or more issues.
Firstly my DME is completely different to the one in the instructions, its a bosh one that has the lateral locking plugs rather than the hinged locking plugs in the images. i have spliced into one of the "pin 4"s of the "x60002" plug ( there are two and i chose the one in light grey plastic instead of the black plastic casing) however i have no idea if that is the correct "pin 4"....
Both "Pin 4"s already have wires in however i have read of owners splicing into this wire and not having any issues.

my second issue is that once i had everything connected as per my understanding of the instructions and took the car for a test drive i found that not only did the cruise control not work but i had also lost the use of my indicators ( my hazards were flashing constantly but no lights on the dash or ticking noise to let me know) , my hood and my windows had both given up and the dash light for the high beams didnt illuminate.
the pins on the light module are all individually numbered so i'm sure that even tho non of the wires are the right color i have the right wires on that end.

shes a 58 plate 2L with the N46 engine

if anyone has any idea where iv gone wrong please let me know

thanks

Where did you get the cable from? This is what I dreaded when doing mine with a forum supplied cable, but thankfully it went better than your experience.

My dad is an electrician and made the wiring for me. Its only 3 cables .... i never expected it to cause any issues. Do you have any suggestions for the N46 Engine ?
Thanks

"HyperGrade" can you pm me your email i don't yet have messaging privileges on this forum.
Thanks

Thank you, Found this post very useful.
Just retrofitted an OEM Cruise Control kit to the Wife's Z4 E85 3.0si 2007.

Kit from Lithuania for £175 via your favourite auction site.
Instructions from :
http://bimmertune.com/index.php?route=blog/article&article_id=5

Plug and play - wire colours matched the car - 3 hours including feeding the blue black wire through the bulkhead and loom grommets

Works at 30mph too so does what it is supposed to.

No problem identifying any of the pins or locations - IF you bother to split the plugs put your glasses onand look at the Pin numbers.

Might attach a few more photos in a separate post if anyone is interested

Hi guys am working thru the retrofit have got to the feeding blue wire into the engine bay

Photo on page one of this guide looks different from my perspective see photo is there another cover behind the glovebox that I need to remove?

Your too high, yo need to go underneath all that then you’ll see the hole on the firewall (with bonnet up)

Thanks was being a dummy my mistake.

Blue cable was easier than expected to push up into engine bay.

Now which connector is it this one and is it pin 39?

For reference to anyone carrying out the retrofit on a pre-2006 M54, I've taken a screenshot of the BMW guide - blue cable goes into PIN 27 of one of the 40 way connectors, looks like the 40 way closest to front of car.

Followed the excellent guide here. However, it isn't working and my brake lights are constantly on. any gurus have any ideas?
