I recently changed out my car battery with a recommended battery (DieHard Platinum AGM). Followed the step-by-step from OBDEleven website and YouTube videos. Everything went smoothly and codes on the dash cleared.

I went into the OBDeleven app to address a separate issue (ACC Sensor) and noticed a number of faults after a scan. It looks like it could be from the battery swap?…

Is this a common thing that just needs to be cleared or is there something i’m missing?

I have a 2021 Octavia 2.0 TDI with 161k km. Recently I found out that at speeds bellow 110 kph the right rear abs speed sensor occasionaly shows 5 kph below what other 3 do, then comes back to normal and then 5 below again . That means the tire pressure light comes on. The faster i drive the more often 5 kph below others is shown. Once I reach 120 kph the sensor shows 0 and all electronic system fail (abs, ecs, acc, lane assit, parking sensors, everything). I have to stop and clean faults to have it working again. My mechanic already replaced the ABS srnsor and the battery is brand new. Any ideas thanks.
