    Code PO170 - Powertrain Fuel Trim (Bank 1)

    I have had fault code PO170 - Powertrain Fuel Trim (Bank 1) on a 2001 Z3 1.9 coming up for quite a while. So far I have changed all the vacuum pipes on the top of the engine, changed the post and pre cat exhaust sensors and had no luck so far. Has anyone else come across this fault and managed...

    Code location Engine swap to 2.8

    Hey everyone! I finally did that engine swap to a 2,8. My question is where to check for the engine code, so I can verify what exactly is on my car. Not sure if it’s a m52TU or a m54. thanks in advanced
