What did you do to your mk7 today?

[messrock]

The shop just called and said the car's done. But they mentioned that the new DP seems close to the plastic ABS shield and to look into getting maybe a metal replacement one. Has anyone else ran into this issue?

Your downpipe used or new? I ordered new and came with a stainless heat shield replacement.

Same here with my Cobb

It’s a used one. So I drove home and it drove fine. Just restarted to head out again and it threw a P2097 for “post cat sensor too rich”. Thoughts?

 

[EpicTech]

O2 either not reading correctly or needs to be corrected via tune

 

[Diggs24]

Yeah, it's a 200 cell cat. Not guaranteed to be code free. Also used, so who knows how it was treated under prior ownership.

@Salami Aren’t you running the same downpipe? I was thinking it was a 400cpsi cat. Did it ever throw this code for you?

 

[Tyler230]

So is that my rear O2 sensor just hanging there?

 

[swcrow]

Yup…. that’s supposed to be screwed into the spacer lol

Ffs. Okay back to the shop first thing in the morning

When the downpipe cools, you could do this yourself. Twist the O2 sensor wiring to the left over and over again, then plug it into the spacer and screw it in.

Golf R? If so, yes. 400 cell GESI cat but not EPA rated. Got a CEL at 400ish miles. Straight spacer with largest port corrected CEL.

2019 Golf R. Does the spacer affect fuel trim or any negative effects?

It's my old one, so... pretty mildly for a hair over 5000 miles, with the most action being the occasional highway on ramp ?

I'm surprised it didn't throw a code immediately...

On one hand, like @swcrow said, you might be able to screw it in yourself once it cools. On the other hand, if you paid a shop to install it, it should be done right without you having to fix it.
