need some help with codes

Okay so recently I decided to sell my VRSF downpipes and I put my stock downpipes back on, and also removed JB4 for a water pump replacement at the dealer.

Ever since the stock downpipes went back in I've been having rough idle and several different codes. Hopefully someone can enlighten me.

2c7e Lambda probe behind catalytic converter, trimming control

2C6B Lambda probe behind catalytic converter, system check

2C7F Lambda probe behind catalytic converter 2, trimm control

also the regular 2aaf

Did I switch my rear o2 sensors around or something?

You've got the rear O2 sensors reversed.

Hmm I was thinking the same thing but I just took a look and they seem to be in proper positions.

The front turbo DP has black wires for the front and rear o2 sensors.

The rear turbo DP has grey wires for the front and rear o2 sensors.

This is the way mine are setup now.

I did recently have to replace one of the o2 sensors (rear o2 front turbo DP) because the wires were frayed.

Now I'm confused
