TT Coupe 150 hp, recommended?

Hello all, I wanted to get a new car within the next 12 months. At the moment I drive the current A3 as 1.9 TDI with 105 hp. The engine power is quite enough for me, because I mostly only “with swim” on the highway. Now I look around something and I have always been a fan of the TT. As motorization I have chosen the 1.8T 150 hp. Now my question: is the engine ok!? That’s already been around Audi for quite a long time?! What is it like with the TT with the S Ervice intervals? At the moment I have 30,000 km and so I drive 20,000 – 25,000 km a year..! I would be happy about experiences or opinions about the motorization!
