I'm trying to read the flash from a 1.8T AUQ Ecu (06A906032HN) but keep getting bounced with 'Disconnecting because no response was received for the Tester Present message.' This is using one of the blue ebay leads, which works perfectly with my 2.7T. I can talk to the ECU using VCDS, so I think this is an issue with nefmoto or with the ECU.
nefmoto does connect, eventually, after many tries using slow init, I once managed to get it to read ECU info, but have never managed to get read flash to work. Should I build a bench flashing harness and get a boot mode lead?
The relevant section of the logs is as follows:

I tried unplugging the clusters entirely, nefmoto would not connect at all.

Tried it again on the bench this evening, it now seems to be bombing due to the imobiliser - is it normal not to be able to read a flash if the ecu hasnt authenticated the imobiliser?
ECU reports programming session preconditions have not been met.
Reasons preconditions failed:
-Immobilizer not authenticated
Continuing despite programming session preconditions not being met.
Negotiating communication timings.
Successfully changed to new communication timings.
Requesting security access.
ECU reports that security access is not supported.
Starting diagnostic session.
Unable to properly start diagnostic session, attempting to continue with current undefined session.
This can occur if the security lockout is running, or the engine is running. Please turn off the ignition and retry if this continues to fail.
Negotiating communication timings.
Too many consecutive unsolicited messages from ECU, disconnecting.

Have to delete Immo before bench flashing works. Use Argdub's tool. Good practice for boot mode too.

Thanks stuklr, that was about to be my next question. Do I need a galletto cable for boot mode flashing, or can I use a normal blue KKL?

Galletto is a cable and program for reading/writing full files in boot mode. You really should have one if you are doing any flashing as a safety net for failed flashes. Its a PITA to make work, but Ddillenger posted an edited copy of the software on here which is easier to understand. You will still need a cable.
To delete the immo your regular blue cable works just fine. Just go under the immo section of the forum and look at ARGdub's tool for writing the 95040 eeprom to remove immo function. I like to save the original immo file, then flash a delete on for tuning. Thei I can restore immo function later if I choose to do so.

Gotta start somewhere. Once you get it done the first time, then it gets easier.

Several weeks, many long nights in the workshop and a few weeks working in the US, I've finally had time to take another look at this problem.
I'm trying to read the flash (with the intention of writing different flash onto it later) from a 4B0906018DC ECU, using a bench flashing cable, bench PSU and either a blue KKL lead or a genuine rosstech lead.
Following the above discussion, Ive attempted an immo off (UK ecu so comes with immo), please see the attached logfile for writing/reading back the eeprom, and the attached bin for my attempt at the immo off. Please can someone take a look and let me know if I've done this correctly? I've set the bytes at positions 12 and 22 to 02 and used the checksum tool to fix the checksum.
I then powercycled the ECU and tried to do a read flash, this is with the rosstech lead, but I have the same issue with blue lead (full log file attached):
ECU reports programming session preconditions have been met.
Negotiating communication timings.
Successfully changed to new communication timings.
Requesting security access.
ECU reports that security access is not supported.
Starting diagnostic session.
Disconnecting because no response was received for the Tester Present message.
Disconnected
Reading ECU flash memory failed.
Any help or suggestions is much appreciated!

I just went through all this grief trying to read a 2001 TT 1.8 180ps ARY engine today.
I used a genuine Ross-Tech cable, and tried slow-init.
This worked, and it negotiated itself to the KWP1xxx protocol version. This caused the Buad rate to be set automatically to quite a high number. At this baud rate it threw the same error as you are getting with the tester present message.
Then, before clicking on read map, I changed the baud to minimum. After that it worked fine, albeit taking 20 minutes to download 1 megabyte of data!
The map looks good in WinOLS, although I've not managed to verify the checksum yet.
