Hey all, usually just a lurker and pick up a thing or two on the forums. Usually figure things out but I am stumped on a few codes on the car. 2011 BMW 335i X-Drive - N55 Engine

I believe that these are all correlated from what I have found on the forums. I have checked the connections and it all looks okay. Ground strap is corroded but isn't broken but I was thinking of replacing that.

I did have DTML codes but that ended up being one wire that was broken that connects to the pump. Those codes have since been gone since I fixed the wiring.

I have four codes going on in the DME that will not clear, continue to come back immediately after clearing. Anyone have any leads or thoughts of where I should ago about figuring these out.

1st- Code 3330 or P15F8 - 87_3Terminal , power supply switched by main
relay, electrical: Short circuit to earth or line disconnection

2nd - Code 3157 or P0444 - Tank vent valve, activation: Line disconnection

3rd - Code 3490 or P0597 - Map thermostat, activation: Line disconnection

4th - Code 3446 or P1521 - BSD message from the oil condition sensor:
missing

Thanks in advance.

Hi there mate.
Did you ever get to the bottom of those 4 codes?
I'm guessing one of the items was causing the other faults to show up?
Regards
