My 1.8TSI recently had the turbo replaced under warranty due to a failed wastegate actuator.
I was getting the EPC warning almost right away, on a cold start. It would go away if the engine was restarted once warm enough i.e when the oil temp reached about 65-70 deg C typically.
The IS12, IS20 (and IS38 as well IIRC) have integrated actuators so that requires a new turbo.
The car is a 2016 NAR and had 50K km i.e about 31K miles.
It is *completely* stock.
I was very surprised by such a failure so early.
After doing some research, it seems I am not the only one.
I have seen few other reports of other 3rd gen EA888 wastegate failures on both 1.8T IS12 and 2.0T IS20.
I'm wondering how common these wastegate actuator failures actually are and I'm a bit worried that my new turbo might eventually die the same way.
