I have a 2005 Bmw 330i zhp. I was driving out of a gas station when it suddenly started making engine noise, then the oil light came on, then the check engine light. I drove it about 2 miles home where i parked it. I scanned it and now reads p0012. I changed out the Vanos sensor $200 later and it did not fix. I have checked the oil filter and it looks okay. I run 93 octane and use castrol fully synthetic with perfect changed invtervals. I reset the code and the check engine light went away but the oil light is alluminated from the start and its RED. The engine makes a ticking/knocking noise as if it has something inside it rattling. Just got the car back a few weeks ago from the transmission shop $2500 LATER and now its doing this. I dont know what it could be and i cant just continue to throw money into it. Can anyone please tell me what this could be? this is really hard on me as its my only car.. 4 Answers
