Oem bluetooth retrofit coding issues

Im not sure what all this K line malarkey is, where should i be looking in the connector?
Ive pinged a message to the seller who was more than happy to help. He says there should be no issue with compatibility and advises gaining access to 77 (TELEPHONE) to finish the coding. Luckily i have a few mates with vcds so i may have to see if they can access that controller with their versions.
Hi Alex, the Kline is what is used for connecting to most of the controllers in the A4 B7, its a mix of Kline and Canbus
The Kline pin is listed on the RNS-E pinouts, also I did not realise you were not using VCDS. What are you using?
Still if you say the module was from A4 B7 then it should be coded right, unless the bluetooth was turned off.

I will check the quadlock pinouts for the k line and see whats happening with that.
I am using vcds but a not gen version. It works fantastic normally but doesn't seem to allow me access to the relevant controller. Im hoping that maybe another persons version will communicate but im not 100%
What the seller has done is collected the various components from different cars to make a kit. Although the module part number is correct, he can't be sure its from an A4, so will need coding for A4
Hi Alex, you will need a genuine VCDS to access the module, the other problem will be if its not from A4 B7, if it was from say an A3 coded for Canbus you may not be able to see it, but I hope this does not happen.
Thats why I said check the Kline is present on the addaptor loom, some cars dont use Kline for diagnostics they use Canbus.

I have removed the loom tape from this adapter to see whats happening underneath. This adapter looks like a quadlock to quadlock patchlead with the wiring for the BT spliced into the relevant pinouts.
I have looked into the rnse pinouts. The K line appears to be pin 5 connector B.
In my case, this is the red wire of the patch lead with the white spliced in for the BT

Yes well it appears that my version of vcds isn't up to the job, which is strange considering its the full version.
The connector for the module has three rows of pins only 2 rows are used with this adapter, swapping the connector internals to the other row of pins, blows the fuse for the HU, which tells me the BT module is powering up.
Plugging in the BT module when the HU is fully shut down also have up the little fan on the back of the RNSE which confirms its powering up.
Ive also made the adaption changes too with no luck
Just a thought norad, where did you buy your adapter lead?
When i popped the HU fuse my vcds came up with the same error message "no response from controller!" This was because it wasn't powered up. Now my thinking is, if the module isn't powering up then vcds can't communicate with it.
Im wondering wether to try a different adapter lead.
Once i have access to the module, i can do what i like with it, within reason of course.

Hi Alex, bought all the parts from one supplier and made sure the module was from A4 B7, this was the most important bit,to insure full compatability.
So if the module was from say an A3, it would be coded for Canbus disgnostics
and you would not be able to access the controller on a B7.
There is a section in the coding to tell what diagnostic protocal to use.
Fo you have full version of VCDS and a real lead, I bought before one of those leads that comes wifh VCDS that you cannot update as its locked to the dongle in the lead, it would not read some of the modules on my car including the phone
I was refunded, without genuine VCDS your just digging a hole.

I just waiting on someone with genuine vcds to have a go, if that fails its back to the seller who provided the parts.
I'm going to be messing around with an rns-e and BT fit on sunday, i'll see what occurs in that process and report back if similar probs and resolutions.
To be honest Rob im really happy with the oem setup, a good map and firmware update will see it working spot on and keeps the dash looking nice and oem.
Im curious to see how you get on with your radio reception too.
my pioneer is not DAB so will have to see what occurs now, don't really listen to radio really, just my cd's .
Oooh fancy, i personally couldn't justify the extra £200+ for the mk2 when i bought mine, but it would have been nice
I have no idea on what a mk1 or mk2 cost Alex , just snapped up a package that seemed very reasonable.
As long as it all works fine that is the main thing.

May live dangerously and get a rear camera aswell,
A man must know his limitations!
I fancy a camera too!
, and sometimes that can be a bad dream with audi's..lol
