Late B6 TIP 01V Soft Coding; active steering shift ?

[rollerton]

So, I grabbed up me some minty LY9D Ultrasport action this weekend. One owner, dealer maintained since day 1, 99k miles, + the 1k to get it home. I'm in a bit of shock dropping from the S6 V8, but i'm starting to feel it. It'll get me the 1/2 mile to work and back.
In the deal I was able to keep my BBS Speedlines, so +1 for me.
Started collecting parts: S4 mirrors, S-Line Euro Paddle shift wheel, S4 Cluster, etc..need some tint pronto!
But, first things first; a few VCDS tweaks.
What's up with 01V soft coding; I was't expecting 7 digits required. I'd like to code the trans module so I can shift via steering wheel while in D; as I've done with my 'other' S6 andd my old Passat.
Does anyone have the proper Soft Coding to enable this? The 5hp19 /older code doesn't do it. I can fiddle with it until I get lucky I guess.
But if anyone knows it, TIA !
So, pics /
As found:



Lets make a deal!


7-Digit soft coding ? First two digits must remain ' 00 ' as far as I can tell.

Why do you need it in "D", can't you just slide it over to manual and use the steering wheel?

Because?

Why does anyone do anything to these cars outside of maintenance and repair?

[MacFady]

Oh no, mod away. I have the same car, I drive it in manual 95% of the time. I guess I'm just missing the point (not that there needs to be one) of being able to still shift manually while it's still in "D", that's all, apart from more efficient engine braking manually while in "D".

Interested in how it worked, functionally, in your other automatic cars you recoded. Would the car just drive normally in "D" with it's normal shift points but you were able to over ride it if you shifted manually? As opposed to how it functions when slid over to manual.

Hopefully you find out, I would like to do the same if possible. Nice ride!

Yeah, basically ^ that's it. In D going down the road, click the button and shift down, up whatever.. it displays the gear change just like in manual mode, then after 7 or 10 seconds reverts to normal D mode.
I have a friend who has a B7 who says it shifts actively from steering wheel while in D, maybe I'll hack into his matrix and see what the coding is.

My girlfirends B6 Passat does exactly this

Audi does not provide for coding "Tip in D" on our B6 A4 1.8T TCUs. This is despite the fact that the 2002 B6 A4 New Model Introduction SSP specifically says otherwise. As it is, only the 3.0l TCUs will code for Tip in D and is the standard implementation for the 3.0l A4s.

I have researched this situation extensivly. The main frustration I had was the firmware of the TCUs that require 7 digits, won't accept coding for anything except 0001002, 0001102 0001012, 0001022 and 0001032. 0001012 disables Dynamic Shift Program, 0001022 and 0001032 are undefined, with no known alternative functions assigned. The earlier firmware with only 5 digits, would accept more coding options IIRC.


Coding values 0001102 changes the tip shift strategy from old to new strategy. New strategy means the trans will upshift in Tip mode just before redline, and will downshift to 1st when stopped. The trans will also downshift with the accelerator floored

.
Old tip strategy means the trans will not auto shift at anytime except just before redline, and will downshift to 1st when stopped.
The coding value 0000002 is not available, resources suggest a zero instead of a 1, indicates no paddle shifters are installed.

Even considering the above, I don't see how Tip in D would work since afaik, the shifter won't move up and down in D, like it does in the tip shift gate.

I just now had the idea that the 3.0l shifter assembly is different than the 1.8T shifter, and implements Tip in D, it's not a coding situation.

Being locked out of Tip in D, really pisses me off.

Well. Shit. Thanks for your insight. 3.0 TCU allows it? I'm going to guess the 3.0 can't be swapped and coded to run ? That's a little odd....I'd assume the transmission would have to be the same, why is the TCU different?
I've clicked away at random values and from what I've found, you're right. Can't remember which spot, I think think I actually got '5' to stick in one spot in the coding by randomly trying, with no obvious change in behavior. On the 7 digit soft coding even some of the documented values aren't accepted.

Yeah, being locked out of optional settings is extremely annoying. As I just noted in my last reply, maybe the 3.0l shifter is different, and is how Tip in D is implemented. I don't know otherwise how the shifter would work in D to select tip up or tip down, since afaik the 1.8T Tip shifter lever can't move up and down in D like it does in the tip gate.

I have never seen a specific Tip in D coding value documented anywhere, only obscure references to possibly related options.

I have an S4 steering wheel with tip shift paddles, and the paddles don't respond with a tip up or tip down response unless the shifter is in the tip gate.

The non option of using a 3.0l tcu is a confounding dilemma, even though the 1.8T and the 3.0l A4s use the same exact transmission, the 01V 5HP19FLA, the only difference is the trans code. I tried using a 3.0l TCU once, and it does not work at all, the trans malfunctioned and was not drivable at all.

The shift in D thing is just something that works from the steering wheel; when I've enabled it, it is strictly trans module coding and steering module/ everything else is left alone. I looked at the steering wheel module coding, I wonder if it's a combination of a different TCU and steering wheel module? I'm going to keep working on this..just because.

3.0 parts being different It's worth looking into.. it wouldn't surprise me...but still, can't think of a reason for a 3.0 to have a different shift assembly- or any difference in transmission from the 1.8?

See my amended reply above. The steering column control module has a coding value for shifter paddles present on the steering wheel, nothing about Tip in D. The SCCM that was OE stock on my 1.8T works fine with the shifter paddles after coding the SCCM for shifter paddles present. The shifter paddles work with the TCU coding 0001002, that is the original OE stock coding.

I was confused about the Tip in D working with the shifter lever. It makes sense that Tip in D needs paddles or buttons on the steering wheel.

There must be some wires that allow continuity to the shifter assembly switch with the lever in D, that closes when the shifter is in the tip gate, on the 3.0l shifters, that circuit is connected on the 3.0l A4s and isn't on the 1.8T shifters. A wiring diagram study is needed.

I'm not buying that there's any hardware difference between the 3.0 trans/ shifter setup and the 1.8T...not just yet. That would mean the 3.0 has more in common with the B5/5.5 VW and C5 system than the 1.8, since a simple TCU Coding change in those cars turns this feature on.
My part # for TCU : 8E0 927 156 AA
And I've found a few 3.0 TCU's with 8E0 927 156 Q <-- and going by date code on the TCU this is a middle production/late 02-03 model. .
I could get one cheap enough...
Cheapo TCU clickery
Browsing Bentley might be worth a headache.

edit; So, browsing EBAY and looking at various TCU's listed for the 3.0, it looks like there are certain versions that have been used in both the 3.0 and 1.8 and a couple that (if listed correctly) share the same part# that were in the 3.0 A6.

You say the B6 3.0 for sure was able to have shift-in-D enabled? I'll give the TCU swap a try. THAT would make my S-line paddle shift steering wheel worth the hassle.

I agree with you that there is no evidence there is a hardware difference between the 3.0l and 1.8T A4s Shifters. When I was investigating this problem before, 3.0l owners all had Tip in D working. No 1.8T owners could get tip in D working. I tried a 3.0l TCU and it did not work, the trans was totally undrivable. The wiring diagrams are the same between the 1.8T and the 3.0l transmission wiring, everything having to do with the transmission is exactly the same wiring. The diagrams are not shown for either transmissions, there is no distinction between them. It must be a TCU firmware difference. I don't know of any coding that turns tip in D on or off, the only difference is the coding for the SCCM with paddle/button shifters present or not.

[rollerton]

Well CRAP. Come on..this is where you say " But....!...." and the good news comes. Right?

Sounds like it's 100% software and 1.8 trans is somehow . Who Hacks trans code.. Daz?

There is a thread on Nefmoto about guys interested in tuning our TCU, but I don't think it has maintained much traction. It was determined that Nefmoto software could download the bin file, but there is not much work done identifying the maps and control data in the binary.
