On reading {on this forum}NEGATIVE reports on ALL VARIANTS of the 1.5 TSI engine fitment .. I am seriously considering keeping the Rapid with its [IN MY OPINION]  faultless 1.2 TSI engine...do you need the stress of repeated trips to the dealer with a NEW car with a "tempremental" NEW engine ??? Build date brought forward by 5 weeks ,is the back log of orders now being sorted ? 

Look at the data, opinions etc but it’s your hard earned cash so make the best decision for YOU. If the Rapid ticks all your boxes keep it until your able to make the decision to change without risk.
