So I am new too the forum hello too y'all who see this but I recently just bought a two door mk6 gti 2.0t and I have owned this car for about 3 months and had a lot of headaches. I'm going after the dealer ship right now about the car and trying too get compensation because this car is a pain in my ass. So one problem i had was the water pump and I changed it out for all aluminum one with new seals and the whole deal. The car ran like shit so I replaced fuel filter for 6.6 bar fuel filter or some shit like that (shit was the most frustrating think too get out and not break the fuel lines) and also got the red r8 coils and Bosch plugs and gapped them too spec and oil change. Doing this made the car drive better with decent pick up again but still idled like shit and rough but I believe I have vacuum leak from the throttle body. But I found little specs of metal flakes could that be from the aluminum water pump it is oil cooled so can it be a possibility? Im gonna go too my buds and were gonna drain oil and check it out but I have not been running it at all and im sad cuz the car only has 104k miles and I like the car but if my motor is trash I cant afford too fix I should have gotten late gen mk7 but that body of the mk6 is just jaw dropping too me. Sorry for the long post but if someone can help or tell me I am retarded or something that would be cool thanks.
