What needs resetting and how to reset ..engine sounds as if it is not getting fuel

Asked by GuruSZLKL May 13, 2019 at 01:09 PM about the 2004 BMW 3 Series 330Ci Convertible RWD

Question type: Maintenance & Repair

I have a 2004 330Ci BMW that I just had a battery replaced by AAA. Now with the new battery it sounds as if it is running on fumes or not getting correct amount of gas to engine. Will driving it a bit reset everything or does it need a code or disconnect and reconnect ? .

You are correct. Replacing the battery will allow the engine computer to lose it's memory for things like idle speed, shift points, etcetera. Allow your car to relearn these things after several drive cycles and it should be okay. I have actual seen engines run better after a disconnect or a code reset.

The OBC that measures mileage on my 2009 335I (and then uses that to measure miles to empty) has gone crazy. Is there a way of resetting, or is it a problem that must be fixed at BMW repair. 1 Answer

All of a sudden, the display that indicates the mileage I am getting as well as the miles to empty has gone crazy - says I am getting 75 MPG. Is there a way of resetting?

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
