Thinking about Modding my A6 when I get it back but I'm worried about high mileage
I got a 2012 A6 3.0T with the last time I saw it 144k miles. I'm gonna be swapping my truck out for it soon and I've really wanted to mod it for awhile. Reading and researching, I've had some doubts come up in the mileage area since she is decently high mileage, has a slight oil consumption problem that I think is a leak from my shitty job of a rushed oil change, but she got the timing chain done about 8-10k ago now. It's been driven slightly since I left so I'm not sure about the exact mileage. But overtime here I want to get it to stage 2 tune area with the upgraded cooling, crank pulley, tune, possibly driveshaft centering support, but I wanted some experts since I'm not the most well versed in german engineering if its even worth it to sink 5k+ into a 14 yr old car with 144k miles in it? and yeah its paid off.
