325i 2006 system too lean bank 2.
Car: 2006 E91 325i SE N52.
I keep getting a fault p0174 system too lean bank 2. So far I have changed the MAF and had a smoke test done which did not reveal any vac leaks. The emissions were also pretty spot on. I get some hesitation and a surge in power at times when accelerating. The light comes on pretty every journey after about 80 miles. Any ideas? Thanks in advance. |
