I recently installed a traction control button for my 2017 Jetta SE (US), but i can't seem to get it to work. I purchased OBDEleven Pro and went through the suggested long coding changes from 2 different sites (one where I bought the switch) as well as some random guy on youtube - none of them made any difference.
My long code from my brake module: A14B400C492A0000850B02E8922200402110F012
The two manufacturers sites suggested I change byte 17 to '18' (originally '10'), and then change byte 19 (originally '12') to '22' (I bolded those bytes above).
The youtube fella was changing bytes 17 and 19 in his central electronics module - It seemed harmless so I tried it and it didn't work so I changed it back to the original. I think he was confused and working in the wrong module, but at this point I'm confused too...so
When I push the traction control button, I get no indication of anything changing with any of the changes above.
Any thoughts? Am I crazy? I'm not a car guy, but I am an electronics guy (bits, bytes, and hex are right up my alley). The pin is in the correct spot on my ABS module and I made sure it clicked into place (I verified it, though I may go back there and triple-check just to make sure i'm not losing it).
Is there a way for me to check with OBDEleven that the ABS module is registering my button push?
I just got this working this morning. Two of the wires pulled out of one of the connectors (the one that attaches to the bottom of the cigarette lighter adapter). One of the wires was the ground...so yeah. When I couldn't figure it out, I tore everything apart and checked continuity between that connector and the pin on the ABS module while the button was pushed. The red and purple wires weren't attached to the connector anymore. I extended the wires, reattached them to the pin on the connector and poof, everything worked.
I had already made the obdeleven changes to the ABS module (NOT the central electronics...darn youtubers), so I'm still not sure if I needed to or not...but it works!!
I bought my traction control button off ECS Tunning (link below). The kit was easy to install but at the end it said I may need to enter the long codes. Sure enough it didnt work and bought the OBD eleven to enter the long codes. Easy to do but still didn't work. After taking everything apart again I realized one of the connectors was not connected all the way. After that was fixed...BOOM, works perfect.

senortoasty2000: Hello everyone, I was wondering if anyone knows how to use the OBDeleven to make it so the headlights I ordered (Ed's LEDS)have the amber LED turn signals always on. I have a 2017 base model GTI

majestic12: Hellol everyone, does anybody has also needle sweep lag ? its not smooth on my virtual cockpit. where can i report this ?

testeronline: majestic12 I would suggest you let VW/AUDI Know as this is there software. Just as an aside what car do you have as I did not think the virtual screens supported this so just trying to increase my knowledge

dv52 (Australia): testeronline: needle sweep can be enabled on some AID displays. In majestic12's case, I suspect the facility is getting delayed because of all of the other start-up activities that happen on ignition switch-on (but I'm guessing)

audia4b8: Hi, I have the same problem, did you manage to solve it? I have been struggling with this for a month and I also have no way of changing it as they write above. It is not possible to change 0 - 1 and vice versa. Through the application and points also does

majestic12: Yea i though so it would be the processes that are starting up when turning on the ignition, maybe they can fix it by doing needle sweep when turning the engine on. Would be cooler to me when starting the engine you see the needle sweep

testeronline: vwjap, I just checked on the Leon Forums and currently V1 and V2 of the dash does not support needle sweep, however it looks like v3 (as fitted in the Atteca) does. Lucky I have the old dials and they do support it (not that I ever look at it )

sgt1297: blackfist13: is there a problem with the car? If not reset all the error codes and see if they come back. If you have issues with the car go through each symptom using the fault codes as a reference. Make model and year?
