Service Bulletin

[syscleaner]

Hello Everyone,

Today I left my car for regular service and they informed me that there is a Field action waiting to be applied. Service guys told me nothing to worry it is just a minor software update. However when I ask "update for what?" The answer is a bit scary in the description it says "Family 0 Engines - Ring Lands, Piston" Later I got home open the GM Infotech and find bulletin. Release date is 2019-04-06 it seems this one is a pretty new one... 


Do you know any detail information regarding this?

Update: When the engine cold started it idle rev higher than usual ambient temp is around 30 Celcius. Engine runs a bit smoother didn't make any long road don't estimate if my consumption changed or not...

Also during mechanics discussing they told me this update is to prevent knocking due to the poor fuel quality... However, I couldn't find anything related I'm bit suspicious after handover to PSA group they made an update for to limit emissions...
