    Hello all, I came to this forum to see if P202A code is related to 23T3 recall...here is my scan.

    this problem started after I started using a carwash at a place that has "Under-Carriage Blast"

    the code returns within one hour of resetting, almost always at re-start ups or shortly after, now I keep BT Torque adaptor plugged in, so I can reset it on the fly, easier than VCDS.

    I read some posts online, but none addresses this question directly, the recall language is rather vague, so

    A)is this connected to the 23T3 recall?

    B) and/or what connector 23T3 refers to, and the circuits that carried by this "Connector" (the 23T3 refers to.

    Thank You

    No, other than the obvious where the sensor monitors the level of Nox while the adblu is there to reduce it, I do not know if they they both use the same connector, or not.

    I am in Canada so to me it is not a deal breaker, as I plan to opt for the Buyback offer, coming in a couple of months, and the code will have no baring on the value.

    Thanks for the reply back. Since my original post, I confirmed the P202A with the dealer, and it is covered under the ADBLUE extension warranty. That was good news. Wish you well on your return.
