Concerning the battery I have a bosch 100 ah but not a 95 ah AGM start and stop, do i need to replace mine with the AGM maybe ?
But the car starts with just a rough idle, and i can drive it normal after, and going faster there isn't a issue.
So the issue isn't from the exhaust system at first ?
Btw i changed the O2 sensor without a reset of adaptations, i still have the issue. I ll do it soon.
