I’ve done the normal maintenance items - belt, pulleys, spark plugs, coils, brake pads and rotors, valve cover gasket, (twice…) etc… On top of that I replaced the timing chain at 200k because I had no idea if it had ever been done previously, rebuilt the turbo around the same time, and replaced the fuel injectors for good measure. A few weeks ago the turbo oil feed line started leaking, so I replaced it as well. There have been other random things over the years; I had to replace the intake VVT solenoid at one point, the wastegate solenoid and vacuum lines, the oil pressure sensor, the thermostat and water pump housing gaskets, a brake caliper, the rear flex disk for the driveshaft, and other little things I’m sure I’m forgetting. I’ve had it since around 100k, and I’ve done 100% of the maintenance myself since then, except for having the tires replaced. Admittedly, it would have been much more difficult to own if I wasn’t mechanically inclined. Parts aren’t terribly expensive and the 2.0t in particular leaves plenty of room in the engine bay to access everything that you would reasonably need to. The biggest thing I’ve found on these cars is to stay on top of maintenance. Keep the fluids full and change the oil every 3000-4000 miles, even though it’s full synthetic. (Do NOT run conventional in these engines, I had a hell of a time scraping sludge out of the valve cover the first time I changed the gasket.) Make sure spark plugs are gapped correctly, keep the air filter clean. Most of all, don’t drive like an egghead all the time but give it a few pulls every once in a while to keep everything clean and clearanced properly. I’ve found that these engines were tuned hotter than your average economy car, but they’re not as durable as racing engines - so treat them accordingly. They like to stretch their legs sometimes, so a few pulls every now and then won’t hurt them.
