Error codes, carista is no help

[Gkit19986]

Hey guys, I've owned my S4 for a few years, I ve been lurking around and the last few days, I've been throwing some codes. I have the carista app, so I've pulled the codes but wanted more clarification on how serious these codes are.


2014 S4 Dsg
Mods Intake, and chipwerke pro, Awe track exhaust
Mileage :27K

p0155 : 02 sensor heater circuit bank 2, sensor 1
p18F6
P1993: potentiometer 2 for Egr ( g466) signal too high

Occasionally I got Epc light
Misfiring on cylinder 1, and 3.

Any thoughts ? I've been thinking to get a proper tune.
The 02 sensor, would that be covered under warranty, or is my aftermarket exhaust voids such thing ?

Don't know about other things, but the O2 sensor, as long as you don't have aftermarket downpipes you should be fine.

What is your CW Pro set to? Perhaps it's too aggressive a setting. Last summer I set mine 6-1 and on a hot day, the engine began to misfire. Set it back to 5 or 4 reset the codes with Carista and try driving around.

This thread should be named "Carista help me find some codes". Carista was very helpful in my opinion.

Hello, I just purchased Carista from Amazon, plugged it into the obd2 on my 2020 sq5 and got the 3 errors below. Any idea what they mean? I am loath to approach the dealer cause they may balk at the idea of me connecting anything to the car and they may threaten to void the warranty:
CAN network gateway:131687
Body/convenience system: 65605
Telematics:458759
