2015 Audi Q7 TDI "Brake Pads!" Light Trouble Shooting

[Carter79]

ERROR LIGHT
I have the VCDS logs for the car at the link below to my Google Docs. I absolutely cannot figure out what the issue is. I replaced every single pad wear sensor to yet to no avail it is still there if anyone can read that log and figure it out that would be greatly appreciated or at least point me in a direction.
VCDS LOG

EDIT: NEW VCDS LOG AFTER DTC WIPE Still receiving the error

You don't say if you've tried clearing the codes - just checking.

Sorry yes with an OBD2 reader I tried clearing the engine light when I had one. I'm not sure how to clear this code with a VCDS

VCDS LOG

Its showing that the wear sensors have reached the below 25% mark, or else the wires for the pad sensors are broken.

Jeez I've changed all of them what else should I do? Should I make those plugs with the wire that just closes the circuit for each one and clean the connectors?

 

[MrCypherr]

Id check the wiring at the connector and see if the pins are making proper contact. Its very easy for those connector housings to break and the pins not make proper contact.

I replaced all 4 I must have broken one or something. I think I will remove the connections and do the old splice the connector trick to bypass the wear sensors as I check my brakes often enough not to need them. I hope this fixes the issue as if its further up the chain I will be royally screwed.

 

[MrCypherr]

If you just loop the wires, youll be fine. After all, its just a dummy sensor to tell you your brakes are low. If you check them often, then I wouldnt worry.

 

[oilhammer]

Just turn it off in the Instruments. Don't even need to get your hands dirty or get under the car, LOL. Worthless sensors anyway.

 

[Mozambiquer]

Yep, as oilhammer said, just turn it off. You can do that in the instrument cluster with vcds.

How does one turn it off? I reset DTC's and still have the error I have a suspicion it is not the wear pads.
NEW CODING

Just have to use VCDS, and go to the Instruments, and poke around in there. VCDS usually has a pop-up helper box that will show all the Coding, or a Long Coding Helper that labels it all pretty clearly. 2015 should have a Long Coding Helper, just scroll through it and find the line that has 'brake pad warning active' and uncheck that box, close the Helper, and click 'Do it' and that line of the Instrument's coding will change and the warning will go away forever.

If that fixes it send me your whatever to send money I'll send $100

LOL.... donate it to the club here.

Went to long coding in ABS nothing about the sensor there
Found "brake system warning light north America" disabled that still get the light in the middle there so to no avail

 

[MrCypherr]

It might be under central electrics (09 module) and check the long coding there.

Nothing there about brakes on my screen just rain sensors etc

 

[MrCypherr]

Does your screen look something like this?

I havent used VCDS in awhile since I have access to ODIS.

Yes but not those options. I have a similar bit 2 in instruments and have that deactivated yet still a light

Should be Byte 17 Bit 2 . Make sure you do a ignition cycle after the coding as been changed/applied.

My central electronics doesn't even go to byte 17 I'll try to send photos

Good luck reading this but under byte 10 there was a selector but I have disabled it and yet the problem persists.

 

[MrCypherr]

Thats odd. I would say then, check [17-Instrument] > Adaptation > Channel 37 or manually loop the wires. Surprised its still showing up.

I have a sneaking suspicion I might be an unlucky fellow and theres a short somewhere up the line. This is going to get really expensive really fast I'll give it a shot with adaptation but I doubt it'll fix it I'll see what I can do I'm a bit stuck now I'll try later.

What are the odds the brake fluid level sensor in the brake fluid cap has failed?

 

[MrCypherr]

I dont think that has any relation cause if it was low/failed then it would have a red warning saying brake level low or something along those lines. Very surprised that since its unchecked that its still showing up.

Well, I booked in with a shop and told them it's more than likely a ground issue or a wiring issue. I don't have time I made the wise decision at 24 to build a house (that was sarcasm btw it was very unwise.) Thank you so much for your help I will try to figure out how to donate here and will update back when they see the vehicle thursday to diagnose the issue.

Its in the instrument cluster, not the abs module or central electronics
