Multiple Simultaneous Malfunction Warnings - '13 S6

[cohall]

So on my way home from work this afternoon, my display lit up and beeps start firing off all at once for multiple system malfunctions. I was driving very tamely on a residential road doing about 30 mph when it happened. Wondering if this has happened to anybody else and how it was resolved? I did a search but didn't find anyone who had something identical to my issues.

Below are the faults I got:
-TPMS Tire pressure: System Malfunction!
-Parking brake!
-Sport differential: System fault
-Air suspension: System fault
-Stabilization control (ESC): Fault! See owner's manual

I also got some notice about being at too steep of an angle (i was parked in my perfectly flat garage at this point), but that notice went away too quickly for me to see exactly what it said.

Anyone else run into this? Any ideas?

Thanks!

Possibly a blown fuse? They all seem related to the AWD module.

This happened to me twice. Both time it was due to a deflated tire at high speed. All the same faults appeared.

Happened to me in my A6 twice. Dealerdid software updates, and if it persisted would likely be a replacement of a module. So far so good

Thanks to you all for your thoughts. Everything was cleared out when I started her up this morning, so I'm hoping it was a freak occurrence and never happens again. I don't think it was the same issue that CorporateAdel had, as I was going at a low speed and I checked and all my tires are properly inflated. I'm assuming either a fuse issue or random electrical gremlin.

Fingers crossed it was just a fluke. If not, looks like a trip to the dealer will be in order.

You get all those warnings when something non-trivial happens and Audi doesn't want to surface a technical message like "MAP sensor value out of range". The warnings will go away when the car is restarted but the code will not. You should be able to pull it with any scan tool to see what it threw.

Bumping this.

Same exact issue. Same exact scenario. Same year model. Just regularly cruising and all these lights came on in order.

Any real fix? Any diagnosed culprit?

Thanks

Did you check for ECU codes with a VCDS: http://www.ross-tech.com/

This is odd, there's quite a few of us reporting this at the minute. Doesn't seem to be tune specific either. There's at least 1 EPL, myself on APR and stock cars. All having it as the same time. I've sent my logs to support at APR I'll let you know if they come back with any ideas

Is this related to fall weather?

The CAN bus ties to a lot of modules, if one of the modules hangs the bus, it triggers multiple unrelated errors: https://en.wikipedia.org/wiki/CAN_bus

I’ve had similar, all related to air suspension.

I’m lowered (Cete module) and if the suspension reaches its parameter limits it triggers a range of warnings. Usually clears on restart and not an issue.

Just had my car in for the same list of issues. Dealer told me "the car wash" caused the faults by shorting a module. They let it dry out and couldn't find any problems. Car is stock and under 35k miles.

Bit of an update. Spoken to APR support they are investigating for my car as it might just not have the left foot braking turned on. I removed the EPL TCU and quickly realised how much I missed it. The shifts are way faster and a lot smoother. Also I appear to be making more power with the TCU tune. Great product everyone should have this IMO

I had the same issue happen 2 times a week ago. Epl had an updated stage 2 file for me, problem solved.

Do you know what the issue was? APR just emailed me back saying they have a beta file to try. So hopefully all fixed. They commented it was a left foot braking issue
