01119 - Gear Recognition Signal (Intermittent) in ABS
 

Hi guys, did anyone experince this error code in ABS?

Frankly i don't even understand meaning of the message, as word gear can mean two things :)
Does it mean ABS cannot talk to tranny or does it mean ABS have problem communicating it's own "gear", i.e. ABS sensors?

ELSA suggests this error appears in ABS when Transmission control unit throws an error.
But my transmission have no error codes in it and works very well.
This is strange.

Below is VAGCOM output. Apart from this ABS error there are no more errors in the vehicle and no warning lamps on instruments panel.

I saw a number of posts in different audi forums in US, UK, Germany and Russia from people with exactly the same situation, but I didn't find any definitive solution of what can it be...

OK, this is what I found about this problem (see picture below).
I specifically insert picture here as I have no idea what they are talking about...

Fault recognition:
- Fault value for gear shift lever position in CAN message gearbox 1 was received.
- Fault value for target gear or engaged gear in CAN message gearbox 1 was received

Rectification:
- Read out error log of engine control unit.
(why ECU ???)

Guided Fault Finding:
- Signal for gear detection

However, this information is from Bosch 5.7 manual and my car has Bosch 5.3

Can anyone comment what the hell all this means and in what direction I should proceed?

A bit more of background: The following 3 control units sit on a dedicated CAN bus and exchange data: 1. ABS control unit 2. Gearbox control unit 3. Instruments panel. One can suggest that it's a connection problem between ABS and Gearbox control units, however, on my 2002 A8 D2 both ABS control unit and Gearbox control unit are located in plenum chamber airtight sealed box (together with Engine control unit). I opened the box and there's are no traces of water ingress and all components are in mint condition, which makes me think CAN bus connection between ABS control unit and Gearbox control unit is tip top.

Special Notes
If found in Brake Electronics, check Transmission Control Module (TCM) for Fault Codes.

Dirty ABS sensors. Removed all 4 ABS sensors from car and cleaned on 22nd of November 2012 with Wurth brake cleaner fluid. Driven car every day until today, 6th of January 2013. No more error.

Same issue was discussed here: http://forums.quattroworld.com/allroad/msgs/65591.phtml.

"I had the same gear recognition code. Appear frequently until I cleaned off the face of all of the ABS sensors. I have not had the 01119 code reappear in over 18 months now."

As I mentioned in another thread this code was on my car when I bought it, so I noted and cleared it.

No warning lights whatsoever (unlike others have mentioned) but just running a regular scan today it had returned - everything else is totally clean.

Some other sites suggest that it "could" be related to gearbox coding and using the tiptronic switches on the steering wheel in "D". I have been doing this a bit while "exploring" the car. :tuttut:

Now I haven't bothered looking at the gearbox coding but I do know the tip switches work in "D" though I don't know if that's standard behaviour anyway. :cool:

not sure if it's standard behavior on the later boxes with "s" sports mode but certainly not with a normal tiptronic box. Mine doesn't activate or light up the buttons on the steering wheel until you slide the gear selector across to the Tiptronic side

Yes, all Audis with 'S' boxes will jump into tiptronic if you touch the steering wheel buttons / paddles.... +++

Pre 'S' boxes with 432 etc will need to manually moved to tiptronic mode before steering wheel buttons will work +++

I can't find it now but earlier I'm sure I read a thread (not here) about gearbox coding to enable the steering wheel switches all the time, presumably (though I didn't note it) for the "432" gearstick.

Mine, as no doubt others of the type do, just reverts to D after a while if you don't touch the buttons again. Still learning. :o

there is a load of codings here for the transmission, not sure if it was the same thing you were looking at

Found it, in here (briefly) http://forums.quattroworld.com/allroad/msgs/65591.phtml not A8 specific though so possibly a red herring.
