I know I'm taking a long shot here as most V8 came with air suspension but I'm really stuck on this so hope someone may be able to help out.

If you have a T2 V8 with steel suspension with 6 spot front brake callipers and access to VAGCOM......,

I need your help!

My 7L 08V6tdi came stock with 4 spot front brakes, I then upgraded to 6 spot but need to change the coding on the ABS module (03) for everything to work properly, unfortunately I haven't been able to find the coding needed, so I'm appealing to the CT community for help.

My VCDS scan shows this:

Address 03: ABS Brakes Labels: 7L0-907-379-MK25E1.clb
Part No SW: 7L0 907 379 L HW: 7L0 907 379 L
Component: ESP ALLRAD MK25E1 0303
Revision: 00H53001
Coding: 0004354
Shop #: WSC 31414 790 00001
VCID: 428160F519666D56DC-8016

The above "0004354" coding needs to be changed, so need someone with 6 spot front brake callipers and the same part number and component number as above to give me a copy of their scan information so I can re-code mine.

Many thanks, appreciate your help!

Thanks for the reply.

I have regular discussions with Stuart, (hedditch) on various things including this issue and yes, he did get his coding issue resolved however his new code does not work with mine as his vehicle has air suspension and mine does not so the assumption is that the coding differs between air and non air suspension equipped vehicles.
Obtaining the code from an existing steel suspension vehicle would solve the puzzle.
I see you have a 2008 V8, I take it it does not have steel suspension?

Ahhh gotcha. I do have a 2008 V8, but I have 4 Pot brakes up front. I checked my coding for the ABS system and it is also "0004354".

Thanks gophurr.

So not all (T2) 2008 V8 were fitted with 6 spot unlike the T1's which I believe were all 6 spots, hum, things seem to be getting a bit more challenging now.

Do you know if all NA T2 V8's were fitted with 4 spot or if 6 spot was offered as optional equipment?

Thanks.

I believe all the the NA T2's starting 2008 were fitted with 4 pots minus the V10TDI.

It's possible there might be some 07 V8 (BAR engine) that have 6 pots, as halfway through 07 is when they switched to the T2 in the NA market.

There only seems to be a couple threads on the forums regarding this...and not much on the RossTech Wiki. I wish I could have been of more help. Please keep us updated with your findings, as I am looking to possibly upgrading the front brakes on my vehicle as well.

gophurr.............you are not the bearer of good news LOL!

Hedditch believes a new ABS controller was used in the facelift T2 (Late 2007 on) so possibly there may have been some of the last (runout) model 2007 V8's still fitted with the 6 spots with the new controller (?).

Long shot, me thinks.

It would be useful if someone with a T1 (<2008) V8 with a 6 spot calliper could post their VCDS listing for Address 03: ABS Brakes Labels so we can actually see the difference between the pre and post 2008 controllers and the relevant software versions.

My 2004 V8 had 6 pot calipers but my 2008 V8 (with steel suspension) has 4 pot calipers front and rear.

The T2 went with a newer redesigned braking system which I am guessing they felt no longer needed 6 piston. No T2 aside from V10 had 6 piston calipers in them in NA. I am purely guessing this is the same for ROW.

Thanks Yeti, not good news but good to know.

Well, unfortunally that seems to have drawn a blank due to the new braking system used on the 08 onwards appears not have any coding for 6 spot callipers.
I wonder is the 08 V10's have the same brake module as the standard 4 spot models powering the V6's??

So....., could someone with T2 V10 please show the coding they have under Address 03, if the brake module detail is the same as appears on mine possibly that code may be appropriate to mine.

Another option may be to check if the Audi or Porsche Cayenne with 6 spot fronts run the same controller??

Thanks to those that helped so far, very much appreciated:smile2::smile2:

Thanks mtnride, your scans go to show that a vehicle with air has a different code to one without air, although the component ID's are different etc to mine but what it goes to show there are different codes between based on suspension type.

Have you tried contacting Ross-Tech directly? Sometimes their coding gurus pull this codes out of thin air...
Yes mate, Ross-Tech have been asked to add some imput on the fact that it seems that the code which works on air does not work on a steel suspension vehicle, fingers crossed that the guru that came up with the code for the T2 air suspension vehicle will be able to wave his magic wand and come up with one for steel version.

Still hopeful of a sucessful result!
