no, i had an oil leak which was repaired by replacing the gasket. at that time the hose broke and had to be replaced. it also has an occasional idle fluctuation. 450 rpms then back to 700, then settles at 600. but only sometimes. Also, when i reset the check engine light it might take a full day for it to trip again. car runs fine on highway and there is no hesitation on acceleration.

Just looking as my e46 330xi MY2001 has a nagging P0171 and P0174 pending errors that eventually pop up. The ccv was replaced, I replaced the O2 sensors (upstream ones), checked and replaced the intake hoses and DISA. Cleaned the ICV valve and throttle body with a new TB gasket. Plugged a missing vacuum port plug in back of the intake manifold no visible leaks with VCG. So at wits end with this issue. Then I read that a possible clogged inline fuel filter may be culprit. I thought a separate ODBII code would show, but some say the P0171 and P0174 would only show for the fuel filter. … read more
