Need help! CEL - Exhaust issue.

[Krzysiuu]

I drive a 2009 jetta TDI manual.

A few hours I hit a wide pothole. It sounded pretty rough but I couldn't find any physical damage. I drove to eat, and a half hour later when I started the car, I got a CEL. I drove to autozone and the code revealed an issue with the exhaust.

I believe the autozone worker said it was the exhaust pressure gauge regulator or something in that nature....

He said it might have been building over time because of possibly aggressive driving, but I'm certain it was me hitting the pothole that probably knicked the exhaust itself.

The exhaust on my car is the Borla, posted below.

So... I'm not sure where to go from here. I'm certain the warranty won't cover me for this at all...
Any advice? What might the long term effects be if this doesn't get fixed?


Please and thank you!!



*Waste gauge bypass regulator valve, is what is affected, from what I found online so far.

Try to get the actual code number. Sometimes the code readers at the auto parts stores, while they give the correct code number, may be the wrong description.

Maybe that was supposed to read "waste GATE"? If so, you really can't just go off of the Autozone description, as your car does not have a wastegate, it has a variable vane turbo.
Sorry, but I can't give any advice off of what little informaton we have so far.

I'm currently still at school and finals are coming around... I will post up the thrown vagcom code when I get back home. Thanks for the help so far friends!

were you able to figure out what was wrong? I have the same P048E code and cant figure this thing out.

[Krzysiuu]

I'm gonna change my oil Saturday and check it out, seeing as how it might just be a sensor or something... And if I can figure it out then I will head to the dealer...

It turned out to be the wiring harness to the exhaust flap. I paid to get it replaced.
