A little back story, I got a 54 plate A3 3.2 V6 which had a Straight Pipe exhaust just recently and when I bought it and drove it home there was no error codes/fault codes. I recently then drove the car again for a much longer period of time and on the way home some the check Engine light came on. There was only 1 error code but now there seems to be 4. Is this because of the straight pipe? I’m not too sure if it’s had a d cat also? I’ve taken pictures of the code (sorry it’s a rubbish obd). Any help would be appreciated!
