Title: Should I replace my turbo? *Attached picture*

Should I replace my turbo?? Looks to have a crack in it although the car is still boosting well. I do have a p0299 code popping up too with an oil leak that I'm not sure that could be related to this.

Let me know :)

p0299 can be a cracked turbo, fissured pcv or diverter valve. In my case, my turbo had the exact same crack as yours and was underboosting a solid 0.4bar throughout the powerband. I've replaced it with a K04 now but the turbo housing was cracked around the wastegate and the CHRA failed. The hot side blades are all scratched up and the propeller has play in every direction. Plus there was a lot of oil in the intake. I'll attach some pictures tomorrow.

I'd replace it ASAP before it lets go and causes even more problems or damage.

Looks like that has seen a lot of heat. EGTs got out of control.  Definitely replace it.
