My 2013 Jetta's CEL lit up for a day or two during the recent heat wave, but it went away eventually. Since the car is under warranty, I called the dealership and they said to bring it in. Seems the "exhaust flap" was "faulty." Apparently it would have cost about $450 if out of warranty.

The code it threw was P048C, according to the work order.

I'm not sure why the CEL went on and then went off. I did notice, perhaps coincidentally, that my SGII shut itself off for some reason during the same 500-mile trip. I unplugged it and plugged it back in and it worked just fine. I'm thinking perhaps the SG somehow cleared the code without me telling it to. I don't even know how to check that with a SG, other than you can do it.

Anyway, that's a long way of asking my question, which is what is an Exhaust Flap? Is it a waste gate?

no its a door that closes to super heat the exhaust to clean the dpf filter soot out.

Dealer told me the first run flappers were faulty as mine was replaced as well...they said the new one is updated and i laughed at them lol

It wont be on long enough to worry another about failure
