What is the VAG Group 23CY Recall
The 23CY software is related to problems with exhaust gas emission levels.
The invitation to install the software update was made to owners of vehicles with the EA 288 diesel engine (the successor to the VW engine with the designation EA189).
The update, it appears has been installed in numerous vehicles in the VAG Group range, from Audi, Seat, Skoda and VW's manufactured since 2012.
Developing Story - Stay Tuned
This is a developing story so facts here may be corrected or changed as we find out more.
As part of the "Update referred to as 23CY" the engine management software in the vehicle's brain "ECU" of the affected engines is updated to address an error detection issue in the SCR system.
The SCR system is designed to reduce exhaust emissions.
It seems that the emissions system of the affected vehicles is not working as it should meaning that it is likely the systems were manipulated illegally and so affected by the emissions scandal.

Information about this update is hard to find but this is a reply one Audi owner received when he enquired about the update
The action is not voluntary but a software change imposed by the manufacturer to comply with the emission values specified by the legislator.
This must be carried out, otherwise, the vehicle does not comply with the registration requirements worldwide, the affected vehicles have been successfully retrofitted and if the damage can be proven to have been caused by the modification, the manufacturer can be contacted. the removal of the software is not possible for us and also not permissible I hope to have helped you so far.
