Has anyone actually successfully recoded their ABS module?

One is the login, one is the coding. The numbers are different hence the massive amounts of confusion. NO idea why Bosch would do that....

**Abuck35** · 03-30-2012 06:32 AM

And the list you posted is the login. Correct?

My list was Coding, I just swapped the numbers around. I fixed it to reflect how Ross-Tech has it laid out on their site (the numbers aren't backwards now).

a2gtinut's list (post 29) is the login.

I just tried to recode my ABS for B7 S4 brakes and it didn't work.

That makes me feel good....maybe I'm not retarded?

**Charles.waite** · 03-30-2012 11:23 AM

Haha. I wonder if Ross-Tech has it wrong? I mean has anyone actually been successful unless it was by accident (ie their coding got zeroed out)?

**vortexjunkie** · 03-31-2012 05:08 PM

What is the workshop code/login or how can I find it mine reads all zero

**vortexjunkie** · 04-03-2012 02:27 AM

I used the WSC12345 tonight and got it successfully coded. I went from having the ABS Traction Control flashing brake light EPC CEL and airbag light on to just this

Worked for me./ My module Died and I got one off ebay from an Allroad. Coded it over now it works np. Been working for over 2years.

**VisionPaintball** · 12-06-2012 07:04 AM

If you replace your abs module with another one with the same exact part number, do you still need to reprogram it?

**CyberPMG** · 12-06-2012 08:06 AM

Hmmm... don't know why I didn't see this before.... I'm now wondering if I should recode my ABS module since I have Stoptech BBK and B6 S4 rear brakes. Never really had any problems with the brake setup before though.

**drjonez** · 12-06-2012 08:12 AM

Try it, I'm guessing it won't work.

me too.

this is my thread, after I swapped steering wheels the new abs module will not code.
It hates me ,
however the feeling is mutual.

**MikTip** · 06-01-2014 03:14 AM

I tried several times to recode for my B7 A4 brakes and was not successful....

**mariosa4** · 06-01-2014 08:27 AM

checkout this video all the way to the end , especially the part that says " you have to put the 40168 code to enable basic settings " .
that's the secret key for ABS unit to keep the loging number

**vhstejskal** · 06-01-2014 08:41 AM

Those sound like the same steps taken to code the ABS module to current factory settings (Current Chassis, Current Brake setup) however the Video doesn't tell you how to change the coding using the correct brake type in coding and login.

or, maybe I'm not seeing it...

**BARRY** · 06-01-2014 07:12 PM

does recoding the unit change the ABS program?

**Waspjr** · 06-01-2014 09:35 PM

Just wondering did you turn your ignition on and throw a code for your steering wheel airbag before you tried to recode ? Sometimes, i am not sure about VAG but the abs and airbags are tied together therefore if you had a airbags code the abs wouldnt recode because of the fault.
Just a thought tho.
I recoded mine with no problems.

I followed the above video to the letter....nothing.

**vhstejskal** · 06-02-2014 04:52 AM

I'd like to either see a before and after of the soft coding for people that say have recoded the module. The only way I see it taking would be to have a fault to begin with.

**MikTip** · 06-02-2014 05:18 AM

Ross Tech explained it to me that all the other modules infront of or in series with the ABS...has to be error free, including the instrument cluster...inorder for it to work....something to do with the way the system works....

I was tempted to get ahold of the software used to reset instrument clusters and try that...

**Waspjr** · 06-02-2014 07:13 AM

here is mine before i changed it for A manual recode.

A slight necrobump...

I've been having an issue with crappy pedal feel, lots of pedal travel before pedal firms up. I currently have HP2 calipers in the front and B6 S4 calipers in the rear. I'm fairly certain that all the air has been bled from the system.

Would an ABS recode help with the pedal feel? I assume the master cylinder is fine since the B6 A4 and S4 master cylinder bores are the same according to RockAuto listings (both 25mm).

Based on my experiences, I'd say you have air still in the system. It took a while to work it all out when I went to big brakes up front and S4 rears.

Interesting. I think I've bled my brakes at least three times over the past few months trying to get all the air out. Last time I tried, there were very fine small air bubbles that wouldn't stop coming out.

How long did it take you?

Drive time was the key, I don't remember exactly how long it took. Engage ABS, that might help.

The B6 A4 and S4 master cylinders are not the same diameter. The S4 MC is a little larger about 26.5 mm IIRC. I have B6 S4 front brakes with the A4 MC works fine. Recoding the ABS only effects the sensitivity of the ABS.

Pedal feel is a function of the MC displacement, that is a mechanical/hydraulic property, ABS coding can't change that. A mushy pedal most likely still has some air trapped in the hydraulics.

**BerNur** · 08-29-2016 09:06 AM

Man I had the same problem couple of days ago.. On the highway my rakes just gave out I had to pump the brake 2-3 times for the brake pedal to get back to normal.

Thank god I was close to home and didn't have much traffic. I let the car sit and went for a test drive the next day and everything is back to normal for now..

It was scary but I was ready. Still determined to solve it but I got nothing. I did not mess with my brakes at all. My hoses to the booster are all clamped and no leaks. My check valve is also new.

Let me know if you figure something out

I thought it may have had something to do with brake boost or ABS because the pedal feel doesn't seem to be consistent. Meaning the pedal firms up more quickly depending on the situation.

If the ABS activates will effect the pedal feel while activated. I know because I can activate ABS at-will with the S4 front brakes. The ABS can't effect how much fluid is moved by the MC otherwise. Engaging ABS will help move air through the lines to the calipers for bleeding, like "drjonez" said. With B5 and B4 brakes, the ABS has to be activated with VCDS to bleed the brakes.

Bad master cylinder.

**onceover** · 11-06-2016 02:57 PM

Bump. Has anyone figured this out? I have one module that I can code no problem - but it has a fault code for an ABS sensor. I have purchased two other modules and can't for the life of me get the coding to stick.

I believe as others have mentioned once you enter the login there is no indication it was or wasnt accepted.You simply recode the module after you enter the login then your soft coding.Then you have to calibrate steering angle sensor.If you stop the procedure at any point,back out of the module or cycle the key the coding will not be saved.Coding isnt saved until a successful steering angle sensor calibration is performed at the end.

I would assume you need to enter the login according to your original equipment or equipment that the donor module came from.

Login

Note #1: After Login has been carried out you need to recode the control module.
Note #2: Special Login 07499 is used for 6-Cylinder Diesel Engine with 1LG Brakes and Multitronic.
Note #3: The Production Codes (PR-Code) such as 1LX can be found on a Sticker near the Spare Tire Well and/or the 1st Page of the Service Manual. Click here to see an Example of a Sticker.
0?xxx: Chassis
9 = Audi A4
0x?xx: Brakes
2 = Brembo 17" (PR-1LJ)
3 = FN3 16" (PR-1LT/1LF)
4 = HP2 16" (PR-1LX)
4 = FNR 16" (PR-1LA/1LG)
5 = FN3 15" (PR-1LB/1LE)
6 = C54 (PR-1LZ)
0xx?x: Engine
5 = 4/6 Cyl. Diesel
7 = 4/5 Cyl. Gasoline
9 = 6/8 Cyl. Gasoline
0xxx?: Transmission
5 = Manual
7 = Automatic (5HP19, 5HP24, AG4, AG5)
9 = Multitronic (01J, CVT)

Ok so right off the bat we have 09 for the login.You need to figure out the next 3 numbers depending on equpiment on the car or donor car.

**onceover** · 11-06-2016 04:14 PM

Yep. I've managed to successfully code the one module with the abs fault - so I know I'm doing it right. The other two modules do not save the coding though.

**onceover** · 11-07-2016 08:09 AM

Swapped the module that I was previously able to recode and now it wont take. What gives?

If I login using the code for a automatic 1.8T - the coding will show 00000 in the VCDS window even after I try to recode to a manual 1.8T.
If I login using the code for a manual 1.8T and recode for a manual 1.8T it will show 04275 (the coding that I put in) in the VCDS window.

I follow all remaining steps to calibrate the steering angle sensor and shut the car off and coding goes back to 00000. This also happens if I don't shut the car off, close the ABS module in VCDS and re-open it. Goes back to 00000 even though it just said 04275.

**blitz2190** · 11-07-2016 08:15 AM

if i remember right the login is the based on the last successful coding the module had, on those two new ones it would be what ever the donor cars had not what you are trying to code it for. I have successfully coded 4 different modules but its been a while, I'll have to see if I can find the guide from ross-tech that worked, I remember there being more than one for some reason.

**onceover** · 11-07-2016 08:43 AM

Both modules came from an automatic 1.8T. When I login using that (09577) they will not take the coding for a manual 1.8T. If I login using 09575 (Manual 1.8T), I can recode to 04275 (Manual 1.8T), but the coding resets to 00000 after cycling the ignition or exiting the module in VCDS.

you completed the coding by doing the steering angle calibration right?
