My 05 525i has 97k miles and I just got an increased emmissions on my screen and im feeling hesitation when im driving can anyone help and tell me what i could be looking at when I roll into the dealer this week ?
Do you have a code reader? A friend with one? Or can you stop by an auto parts store that will read the codes for you? When you have the codes, post here and we'll diagnose. Could be as simple as a worn out O2 sensor...
When i had that code it was failed secondary air pump to cats. There are two on my car one leaked and failed. If you can just get the code read the repair s can be DIY with the book.
