I'm trying to set the Readiness to ready without driving

tests performed

After running Basic Settings "Automatic test sequence" [Go!] followed by holding the brake and gas pedals as prompted by the controller.
after several ECU resets and re running the test unsuccessful.


Address 01: Engine (J623-CTUD) Labels: None
Part No SW: 8R0 907 551 G HW: 4G0 907 551 A
Component: 3.0l V6 TFSIH07 0004
Revision: --H07---
Coding: 2A2A0034052600060000
Shop #: WSC 06342 000 00000
ASAM Dataset: EV_ECM30TFS0218R0907551G 001004
ROD: EV_ECM30TFS0218R0907551G.rod
VCID: 3C7D5A86B75CBDDE41-8068

No fault code found.
Readiness: 1110 0101


Eventually got an opportunity to take a short test drive seemed like the only way,
after test drive the Evap is Incomplete and that's another pain, need to initiate the evap test manually.

anyone got any ideas ?

We have a scan from the OP but I can't post it here without his explicit permission. This thread explains the code tags Jack mentioned if Andy chooses to add it to this thread: How to post an Auto-Scan

Jack, we experienced something similar experimenting on Uwe's 2012 3.0L A6 (CGXB) with the engine controller basic setting selection "Automatic test sequence". Jef was the one testing but I believe all but 3 Readiness bits were passed when the engine controller claimed it Finished Successfully. So, I would need to try numerous drop-down menu Basic Setting operations in various orders live-time on one of those cars but .. it is entirely possible that the newest (UDS) engine controllers aren't truly capable of setting EOL readiness in a single Basic Setting Operation like the older CAN Protocol cars.

I suggested the OP try these at idle in reply via email this morning:

Tank ventilation valve check
Read out system status ctrl module for fuel tank leak diagnost.

I have always found that visiting each test individually was the best way for EOLE or Force of Readiness tests.

Now this car being UDS, and Simos must be done from the drop down menus.

It would be interesting to see if running a test in a certain order creates a bug loop in the software.......seen that one before and with no DTC.

My first question would be........... is this car tuned, and is maybe readiness being blocked from a test mode due to FOD?

A side note for other readiness glitches...........
I like to go to undocumented channels and flip the test ON by turning basics ON...... such as example in earlier ME7.1.1 Kline or even TP2.0 CAN cars seem to have binary tests like in the old A3 cars from 96-99 in upper 200-255 area.

Not exactly the same animal, but I was able to *MOSTLY* set readiness in my 2015 GTI which uses UDS by getting it nice and warm, BS for "Automatic Test Sequence" and flooring the gas and brake. It varied engine speed on its own including a scary brief trip up to 4500 rpm and finally got everything passed except EVAP. Even after topping up the fuel tank (it was kinda low) and running the test again, EVAP never tested. Shrug. It was handy to pull up this Advanced Measuring Value to watch the steps count down from I think 18? to zero: "Test steps still to be performed"

LDP tests are sometimes aborted after being warm depending on firmware.
Early cars even sited a specific IAT or you abort.......

It could also be that if the LDP wasn't initiated first before the N80 you get a road block for the shared bit to pend.

Force of Readiness tests.

I don't think the term "force" is a good one. To me, it seems more like a request, as in:

Agreed........ not such a good term, however, is the term used in the repair manual since 1995>
