Solving chronic intake leaks and restoring power on high-mileage 3.0 T
My 2014 Audi Q7 3.0 TDI hit 155,000 miles last month, and I was getting totally fed up with constant intake manifold runner codes, sluggish throttle response, and endless boost leaks near the EGR setup. Every time I fixed one brittle plastic fitting under the hood, another cracked two weeks later, making me hate driving a car that used to be an absolute highway cruiser.
