The Volkswagen T6, a popular van known for its versatility, sometimes presents a peculiar issue when scanned with VCDS (Vag-Com Diagnostic System): a “Readiness N/A” status instead of the expected readiness bits. This problem appears prevalent in engines with codes CXGB, CXHA, CXHC, CXEB, CXEC, and potentially others within the CXGA and CXHB series. These engines are found in both the T6 and early T6.1 models.
Several symptoms point to this issue:
-
The readiness button within the engine module in VCDS fails to report the status, returning an error message concerning non-compliance.
-
Utilizing OBD-II Functions > Mode 1-01 Readiness, however, correctly displays individual components and their respective statuses.
-
Accessing Engine > Advanced Identification/FAZIT under VCDS Info reveals “Readiness: No script available.”
-
Intermittently, accessing the engine directly might yield the correct “0000 0000” status, but this is unreliable and difficult to reproduce consistently. “N/A” remains the predominant result, especially in Auto-Scans.

While the “Readiness N/A” error is common in certain T6 engines, newer engines like the DMZA, DNAA, and DNAB, found exclusively in the T6.1 models, seem to report readiness as expected. This suggests a potential software or hardware difference between the generations.

Possible workarounds and solutions are being discussed within the Ross-Tech forums, often involving using specific VCDS procedures or checking for software updates. Further investigation is usually necessary to pinpoint the exact cause in each case. Topics related to this issue on the forums include discussions about parking sensor faults, rear camera coding, injector problems, and general coding issues in the T6 platform.
It’s crucial to use updated VCDS software and firmware to ensure compatibility with the latest Volkswagen models and to access the most current diagnostic procedures. Consulting the Ross-Tech forums or contacting their support team can provide valuable insights and potential solutions for resolving the “Readiness N/A” problem in your Volkswagen T6.
