Mk6 LED Taillights

**Hail** · 09-08-2010, 08:15 AM

Took my car to get coded this morning and they couldnt detect an error through VCDS...even though the blown globe light is showing on my display.

They went into the control module and selected "18" but couldnt gain access.. I'm sure there is something they arent doing right..

In addition...before I went to get the re-code done I noticed after leaving a stand still that my kms accumulated (showing in the bottom left hand corner of the MFD) changed to a symbol showing "- - -" and "km/h" with a small speed type image and then returned to my kms total at the lights. Will check the manual when I get home and see what this means.

When you say "they", who is they? And did you see them using VCDS, or was this information relayed to you ?

It just means you hit the cruise control reset.
When resetting the cruise control memory, mine will blank out, have the ----- and then go back to distance since zero'd.

They being a APR authorised dealer (figured they would have VCDS), Yeah I was standing behind his shoulder.

BTW I got my car GTI in Nov 2009, not sure of build week...

Edit: OK - I went on to Ross-Tech's website and worked out what the bloke was doing incorrectly, they went to 18 Supp Codes... and it kept saying not available.. They needed to go (based on AdamD's post) to 09-Cent Electrics -> Coding 07 -> select "Long Coding Helper" - > select byte 18 -> change binary code to 00000100 -> press ESC - > click "Do it".

Or you could have used the original link I sent out http://www.mk6golfgti.co.uk/forum/in...opic,81.0.html

I think I told you in a PM to print it out and take it with you when you got it coded.....

Just to clarify on the long coding helper entry for byte 18: the value to set (for my car anyway) is 15 in hexadecimal, and 10101 in binary, however VCDS may require up to a full 8 bytes be entered when changing the value (I didn't actually make the changes when my car was being coded, but I did observe). If this is the case, just pad with leading zeros (so, 00010101 for example).

EDIT: For more information, and the correct coding information for a March 2010 (likely > week 45 2009) build GTI with halogen headlights, see this post.

Hi Ozram,
not sure if its my server throwing a curly at me but I cant open the link you
posted (tried it 3 times) so just wondering if you could try opening it from
this thread please?

Still working on saving for these cool LED's mate, may send you a PM again when I
have the $$$.

Waiting for dealership to call me back today regarding cost from them to re-code
or if they can/will do so.

You have been such a great help regarding these LED's for all who are interested,
along with info from Adam as well.
So good on you guys, much appreciated

That link was inadvertently truncated. Here is the link you're after:
