yosam34 Posted June 10, 2023 Report Share Posted June 10, 2023 Hi guys, new here! need some help please. I had a mad idea and purchased a 2002 330ci as my everyday car. I absolutely love it but it has a few problems that I am slowly working through. Alternator failed so I have replaced this, since replacing there is a constant whistle at low RPM - when I disconnect the alternator the whistling stops - I am presuming that I have a dud alternator? I also have PPPPP or Code on the dash (I have tried leaving battery disconnected etc, the dash switches between PPPP & code). I've put a new Bosch battery on as well, as the other was small & wedged in with cardboard. Pulling my hair out a bit. Any advice greatly appreciated. Many thanks Sam Quote Link to comment Share on other sites More sharing options...
momo Posted June 10, 2023 Report Share Posted June 10, 2023 Your cluster needs to be reset. It can be done with software but i've heard this procedure works (taken from E46 Fanatics): De Sisti said: Turn key in ignition to position I Remove fuses (10, 34, 43) for the dash Re-insert the fuses (you'll hear a Whirring sound as you do so) Turn key in ignition to position II Quote Link to comment Share on other sites More sharing options...
