Error messages on dashboard fault codes

[jbabl]

2015 S3
My car is stock,25000 miles
Just started getting a crazy bunch of warnings while driving- tpms malfunction, stabilify control, dynamic lights etc

Hooked up obdeleven, cleared codes
Nexr day, same thing, now even more frequent 
Warranty just expired last month
I might take it to the dealer and see if theres a recall campaign of some sort, software upbrade for Ecu or reset procedure(?)

Any suggestions or if anyone has experienced sometging similar, please post your solution

Thnx

Sent from my Galaxy Tab A

[jbabl]

Just scanned and cleared again-is there a difference between scanning
/connecting obdeleven with engine running or just ignition on?

Thnx

[Thirsty]

I would recommend to do scans and coding with ignition on and engine off.
Of course you must have enough battery voltage.

[jbabl]

Will try cleaning batt terminals and RR abs sensor-

[jbabl]

Is it possible to disconnect the ECU with the car turned off? Thought of inspecting the terminals and spraying electrical contact cleaner just in case(Florida humidity here)
Thanks

[jbabl]

Well, hopefully this will help others-I searched quite a bit on the subject looking for someone with a similar issue. The warnings on the dash became incessant, chiming, yellow warnings about stability malfunction, TPMS failure, hill assist failure, headlight failure, parking brake, etc.
Cleared all codes with obdeleven many times, to no avail. I thought I'd replace the RR ABS sensor, and it's only about $29(close to $100 at stealership)

But then I decided to do what I posted previously-disconnect and reconnect the ECU. I searched for that as well, knowing many people have sent their ECUs to APR and other tuners, but I didn't find a DIY procedure on how to go about it.
I then decided just to pull the latch that release the ECU harness with the car off-that released the top one, and I pressed it back in place. There's a second one bellow from what I can tell, but I decided to stop before removing the connectors completely since I don't have enough info on it-BUT, that seems to have done the trick! Like everything else involving connectors, it seems that the communication error might have been due to humidity or something. I scanned with obdeleven, cleared codes again, checked live data, etc. Drove the car normally, then aggressively, no warnings, no codes! So unless something changes(will check again this afternoon after it stops raining)it looks like reconnecting the ECU was it-
Also, my batt is only less than a year old, never suspected-

[jbabl]

And I just did another drive this afternoon, no issues. Re scanned with obdeleven, no issues-

[jbabl]

Well, it happened again-released the upper latch on the ECU again, pressed it back in place, re cleared the same codes, no message again. But what I'd like to do is remove the ECU completely to check and clean the contacts with electronic contact cleaner spray. May have to disconnect the battery to reach the ECU's bottom latch to remove the harness completely. So to disconnect and reconnect the battery, is there any recoding needed or is it ok to disconnect both terminals? I've read that there is a sequence to properly disconnect and reconnect the S3's battery(?)

If after cleaning ECU connections I still get a persisting issue, I'll consider replacing the RR ABS sensor-
I can also take the car to a friends indie shop, I suspect the dealer will charge an arm and a leg just to diagnose.

Any input appreciated
Thnx

[jbabl]

I found a page showing ECU removal:

www.audi-sport.net/xf/threads/how-to-guide-–-mtm-m-cantronic-tuning-box-fitting-installation-guide-–-s3-8v-model.267054/

I went ahead and took it out, sprayed CRC Electronic contact cleaner, then compressed air to completely dry it out. So cleared codes again, will see if it's it-
Can-bus connector has a seal around it(orange colored)
It could be that humidity was the factor-

If problem returns I'll have to look into the RR ABS sensor, or see if the ECU itself is frying out-
JB

[jbabl]

So I had some time to investigate further-I decided to look at Live Data and move the car on the driveway while looking at the ABS sensors.  The Right Rear showed 0 mph, the other 3 indicated about 2mph-so I decided to replace the sensor.  Cleaning it did nothing, but I just installed the new one, re cleared all codes and it's back to normal.  The bad sensor created the ESC, TPMS, hill assist, headlight errors, and all the communications issues.  But, it was good to take off the ECU, clean contacts, etc
My paranoia was that it was going to be the ABS Module-replacing the abs sensor was easy

HI, I have an 2017 Audi TT, i am having the same problem, so I check for codes and it throws right wheel sensor, so I change both front Wheel speed sensors... After I finished mounting the new wheel speed sensors, i reconect the battery and boom the car won't start, I press the start button and nothing, the dash turns on, the lights, except the windows that do not open... I am really frustrated...

Not much information to make an informed response. Make a SCAN report and post-up a copy as an attachment so we can see how the modules feel

I can't provide a scan report, when I connect the battery the dashboard turns on but the car doesn't start, it doesn't do anything, it doesn't respond and it started happening after changing the wheel speed sensors, the car simply won't connect to the OBD ELEVEN, what was happening to the person who made this post is the same thing that was happening to me, until I changed the sensors and it didn't turn on anymore...

[dv52 (Australia)]

kryptosaihimura21 : OK - I'm not sure that I understand what you mean by "when I connect the battery the dashboard turns on but the car doesn't start". 

If you mean the engine running - OBD11 does NOT need engine-ON - it only needs to see battery volts at the OBD-port (called "Terminal 30 volts"). However - to make a SCAN, the modules need to be woken-up from their sleep state. This happens when you turn the key to the first position (i.e. ignition-ON) - which generates a Terminal 15 voltage. But again, it's not necessary to have the engine running.

So, if the OBD11 software won't connect to the dongle - measure the battery voltage and also check the battery rail voltage at one of the fuse blocks. 

If you can't wake-up the modules by switching-ON the ignition, you will need to check the Terminal 15 Volts. Probably the easiest way to do this is to listen to the relay that switches-ON the T15 rail voltage - which is called J329.

J329 is shown on the diagram below - it's item 6 ("B4")

When the ignition is switched- ON/OFF, you should hear the relay click
