clutch has a 12k mile warranty on it. Its a wear item so there really isn't much of a warranty, but its up to the dealer whether they want to warranty it after 12k or not
po171 code is prob a vac leak, check all your hoses and see if any are cracked, if so replace it.
But i bet you need a new wastegate actuator. How many miles on your car?
hey i have one, with a little bit of curb rash about 3 inches long, i can take a picture tomorrow and send it to you.
make me an offer for it i have no idea how much they go for.
make sure you are getting all the air out, you may not be, bleed the brakes again do it in this order RR,LR,RF,LF. Also make sure you are closing all the bleeders tight, and check for fluid leaks at the calipers and the lines that you replaced.
You can still have a pulsation in the pedal if its the front brakes...
but a great way to tell if its the front or rear brakes is to drive and pull the e-brake up holding in the button(do not release it or the brakes will lock up). And if you feel a pulsation its the rear brakes, if no...
