Curious if READINESS codes even work on AHU???
Any new data on this subject? I have a '98 Jetta TDI w/ AHU engine. Emissions testing is telling them that the EGR readiness code is not complete yet. It has been over a year since I have disconnected the battery, yet I can't get the EGR to the READY state. From what I can tell thru using VAG-COM, only 01 (engine), 15 (airbags) and 56 (radio) even do anything on my USA Jetta with manual tranny. Scanning 01 shows no problems, but when doing a READINESS check, it comes back with "Readiness Status Not Available! Vehicle not OBD-II compatible? Data: E7 11 20 20".
I'm beginning to think that it may never work, but I only get a 30 day extension on my plates with proof of failure caused by READINESS codes.
Even with the VAG-COM, I'm getting nowhere fast!
Here's my log file:

VAG-COM Version: Release 409.1-US
Control Module Part Number: 028 906 021 JB
Component and/or Version: 1,9l R4 EDC G40SG 1457
Software Coding: 00002
Work Shop Code: WSC 00066
No fault code found.
I've tried reading Block 017, but it just won't read it. It just hangs....
Any input is appreciated!
