Ok so got my exhaust installed over this weekend and they did a full cat back exhaust using Meisterscahft Exhaust and Invidia Mid-piping. Everything went fine until they turned the car on they got some engine codes, which were P0031, P0051, P1020. Anyone got any idea what it could be causing this, the car is like its in limbo mode so basically I cant really rev it up past 4K rpm, all help is appreciated.

Are the o2 sensor wires twisted? I remember reading somewhere that twisted wires throwing codes.

They probably screwed the wires up for the o2 sensors. If you got those codes as soon as you turned the car on that's definitely what happened.

are you supposed to install a CB exhaust on an AWD. i thought CB for RWD... and AB for AWD... hope you get it rectified. got my fingers crossed for you...

Thanks for the input he tried to order new O2 sensors so I have to wait tell Monday.

Yes this was custom made for the AWD, they had to bend the top part in order to get it to work.

Wait, so they were able to bend the pipe? They did not use your OEM mid pipe as a donor?

Nope I didnt want them to use that. They would have had to cut up the OEM in order to do that.

They probably twisted the O2 Sensor wires...the best thing to do is to move the rubber wire insulation up so you can see the wires then twist it (3 times the opposite direction), so then when you tighten them back up the wires go back straight...then there should be no problems. I hope that they didn't end up twisting the wire to much that you have to use new O2 sensors...I hope it isn't the mid-pipe section from Invidia that is doing this...if so that would be weird (like a leak or something)...

good luck man!

If its like the 3G, the interior has to be taken apart to gain access to the connectors for the o2's.

I would specifically request that they not use universal sensors that allow them to cut the wires and solder/butt connector them together to avoid the extra work of taking apart the I interior.

Yes this is the invidia mid pipe but I'm pretty sure there isn't a leak hoping it's the o2 sensor and I can be on my way tomorrow.

They are using oem that's what they ordered from the dealer. Will update everyone tomorrow on what it was if fixed.

So it was not the O2 sensor so it had to go to the dealership. Awaiting the verdict.

Ok so this is going to be great, the verdict is the MAF Airflow sensor was bad and the O2 sensor blew a fuse. She is now in good health and picking her up today. This is really weird never heard of this happening.
