Problems with n54 335i
Greetings from Belarus!
The problem is like this - check engine regularly appears on the panel. Consumption increases, reduced dynamics, sometimes raises the idle speed or just shaking a little. I have two errors - lambda before catalyst (mixture too rich) and after the catalyst (mixture too lean). Both lambda in the first bank. No more mistakes. Exacerbated if the ride is very active. Any ideas what's wrong? The catalyst? |

Are you using 91 or better fuel? Also you mentioned downpipes, did the check engine light begin after the downpipes?

Using only 95 fuel. I have no downpipes. I have stock pipes with cats.
As I said before I have two errors - lambda before catalyst (mixture too rich) and after the catalyst (mixture too lean). Both lambda in the first bank. No more mistakes. |
