Hey Everyone,
It’s been a while since I’ve posted (last post here about my CEL Saga ( http://audirevolution.net/forum/index.php?topic=3933.0 ). This time, I was driving the car around 40 MPH, and had the EPC/Traction Control/ CEL lights come on and the car went into limp mode. I had the car towed to the dealer and today was told it’s a MAF issue that caused a throttle body to get stuck open (At least, I think that’s what they said). Based on some cursory research online, it seems this may be a somewhat familiar set of symptoms that result in the same “fix one part, drive away, fix another part, drive away, repeat”, so I’m concerned it may not be just a MAF issue. Below is a link to a video so you can hear what’s happening. Any guidance here is appreciated! (still haven’t bought the VagCom…)

So far I’ve had the following done from the first set of issues:
Entire manifold replaced
Checked for vacuum leaks and replaced a hose with a very slight crack
Carbon Cleaned (walnut blasted)
New spark plugs
New Coil Packs on cyl 5-10
New PCV (Crankcase Valve)
New Fuel Injectors on cyl 5-10
With the new issues they’re replacing:
MAF
Upper Control Link Bushings (perhaps unrelated, but noticed while doing the inspection),
