Hi! They change the diff oil in the last service less than 2000km ago...but I don't see in the bill the transmission oil change so maybe they didn't change it. I'll ask about it!
And you're right...they didn't put any +FM in the diff! Just the Castrol oil...and believe me in the US clients get a HUGE better treatment thant in UE!
