Those things are known for problems (TT), especially the convertible. Coilpacks are failing left and right on all VW/Audi engines. Read the vw forums and you'll know. There is no official recall and most owners are stranded without their cars while they wait on these parts to come in because they're on back order.
It's still a great car though. Very small for the price, but a good car overall. I hate the turbo lag though. Is it the 180hp or the 225hp?
