170 TDI Scirocco has a red "I" too to distinguish it from the 140TDI, both badged "2.0 TDI". Used plenty of times now and in the past, mainly to distinguish different output versions of the same engine unit. This badging implies greater potency over the current GTI to those familiar with the system.
10bhp greater potency
My dealer hasn't even mentioned these changes even though I have a car on order.Shall I shout in March when my GTD doesn't have " that" sound ?
