I've had no luck thus far in my quest for contracting any aftermarket tuners for this job, since it seems to be very unorthodox and potentially never has been done before.

Please let me know if the following logic is correct in my understanding of the Me7.1.1 ECU.

Some ECUs (B5 S4, I thin) have two sets of of maps: Automatic and Manual.  So the soft code has to be the determining factor in which maps are accessed, correct?

In an effort to try and adapt something for my RS6, I can refer to the the S6 Manual and the S6 Automatic ECUs with are mutually exclusive (no dual maps).  Obviously there exists no OEM manual ECU code.

If I can take the code that looks at the soft codes from RS6 manual code and replace it with the code from the S6 manual, then this could be a solution.

For reference, I currently have:

1. the TCU disconnected and disabled in the canbus via the cluster
2. have an S6 ABS controller installed and correctly soft coded for a manual
3. have the current RS6 ECU soft coded to a manual.

When I run the RS6 stock flash I get faults on the ABS and ECU:

1. ECU - Missing TCU (doens't throw a CEL though).  I believe that even though the TCU is out of the can bus, something in the ECU code is checking for it.  I need to get rid of this.

2. ABS - Controller incorrectly coded.  I believe that the ECU dictates what ABS soft codes are allowable and I need to get he ECU to allow this particular soft code.


Also for reference, if I reflash the ECU with the S6 manual code (can't start and run the car with this of course) all of my faults and errors are gone.

Thoughts, ideas, opinions?  Anyone out there willing to advise me on where to go to get this done or how I can start in doing this myself, etc.

Why not write a letter to quattro and tell them you are driving their flaship...  you never know...

So are you just trying to disable those two fault codes, or are there other problems you are having?

abs and ecu softcoding probably needs to be changed the way you did it. but softcode doesn't determine which maps are accessed... the actual files are different on the s4... certain torque values are different.  I'm planning on comparing the s4 files and making changes to the rs6 file based off their differences. 
send me a pm and I would like to help.

Most ECU's that are not TDI ECU's do not allow for switching of the transmission type. You must flash manual SW.

Being that the RS6 never came with the automatic transmission, the only option you have is find a different application that came with this motor and a manual transmission or hack the ECU code. Disabling the DTC's might work though.

Bump on this.

Any more thoughts on this?  I know it's a huge undertaking.

Can anyone recommend a source to contract with?

I'd love to try this myself, but it woudl take years for me to get it done.

it shouldnt be that hard.  you can either locate the dtc's that are being tripped and disable them like mentioned earlier. or  split the s6 manual trans portion of the flash with the rs6 engine portion.
ive done this with a couple s4 tunes and converted manual tunes to auto with no problem.

It has been done before by MTM in Germany. The car is called MTM Audi RS6 Clubsport, here is a test video from german tv

at 3:28 the testdriver talks about the fact that they converted the car to manual transmission.
i hope i could help you a little bit,
greets from germany

i found some details on their homepage but there is no english version of this

Have you managed to make any progress on this?

So it's been over a year since SteveKen posted in this.  Steve, any progress?  What have you tried, and where is your car currently at?  What were the actual DTC numbers for the ECU and ABS CEL?

I can just say BTDT at this point :)

Hopefully the smile at the end of your comment will have me smiling ...

... And saying "I told you so" to so to certain folk...

Well, hopefully I'll soon figure it out and be smiling as well.

Steve, do you mind giving me a quick synopsis of where you're currently at and the path you've traveled?

He no longer has the car.

That's a S6 conversion to RS6 ;)
There were a lot of myths according this conversion.
Different gearbox housing layouts etc.
I can't check this, but old V8 automatic gearbox and 01E gearbox had the SAME design.
How ever.
Can't you leave the TCM in the car? ;)
Some guys told me you have have to update the instrument cluster panel.
But I checked this: http://ok-chiptuning.de/

According to my information they did a "real" RS& MT conversion.

The Cluster works fine in my 2.7 a6 2003

The abs Box can be recoded with the correct login, i did it on 2003 s6 manual conversion.

The magic is mabe in the ecu File to tell him how to be a Manual car.

Way to necro this with incorrect information.
The RS6 ABS can NOT be recoded to manual. S6 ABS is different because there was a S6 manual from factory.

Exactly what pri said I had to get a new ABS module cluster is fine once the ABS is coded properly.
