    Hi, I've got a problem with the battery light on my e46 320d touring (europe) dashboard. When I just insert the key and turn it on until the position part, I can actually see most of the lights on the dashboard light on except the battery red light. The battery light appears for just one second...

    Hey everyone! My E46 325i just crossed 200k miles a few weeks ago (Yay! I made it), but with that milestone has now come some very strange electrical issues that are making my head spin. The predominant issue I'm facing is what seems to be the alternator not producing enough current to run the...

    I have an e46 M3 that I keep in dry storage. Yesterday I took it out for a gentle run to get heat through the block & chassis. I pulled up outside the garage and turned the engine off to open the door. When I restarted the vehicle, I could hear a strange noise so switched the engine off. I then...

    I've been tackling some issues that my car has been facing recently. Replaced the old intake boots and vacuum hoses for the SAP check valve. The car drives fine, but when I come to a stop, my RPM's will drop to 500 and then settle around 550-600. It used to idle at 700. Started the car this...

    I was sitting in my car when the radio went off, I turned the car off and it would not come back on. I rang my mate and it was running after a jump start but felt as if it was dying when I was driving home. I then jumped it off my dads car to take it to the garage but broke down on the way. The...

    Hello everyone, I purchased an 03 BMW 330i a few months ago as my first car and I absolutely love it. However, with it being my first car, I ran into a problem the other day that I don't know what it could be said from it being either the battery or alternator. I was cleaning out my car and...

    So about 6 months ago my maf went bad and my car was throwing up lean codes even though there was no vaccum leaks. A new maf later and my car was back up and running and no more codes. recently I’ve been getting a lot of odd electrical issues, and I’ve put it down to the alternator as it...

    Hi everyone, I recently had some issues with the car not starting. It was giving a single click and not cranking. I noticed the battery light wasn't coming on when the ignition was in the ON position (before starting the car). Changed the alternator to a Bosch 150a 14v refurb unit. Old unit...

    Hi all, I'm having issues with the M54 90A Valeo Alternator (part number 12317501592). A few days ago I noticed that the lights of my car, including the interior lights which are to my knowledge not managed by the light switch module, are slightly flickering at all rpm. This happens with...

    Recently on one of my more spirited drives I came across a large pothole on a back road and hit it. There was no cosmetic damage however, I noticed that there is now a red battery light on my dash that will occasionally go away if I hit another bump. Thinking perhaps I snapped the accessory belt...

    So my car’s been making a noise all the time, even when parked. Took out the tensioner pulley and idler pulley and realized it’s probably from that. Took it to the mechanic a while back for a new transmission and they gave me back this random plastic cover. Didn’t think much of it, but just...

    I have a 2003 325i with 156k miles on it. A few months ago I started having electronic issues with the car not starting in the morning and the radio shutting off. I noticed the battery was quite old so I replaced it with a OEM battery from a E90 dated 11/17. The car daily drove for a few more...

    Hello E46Fanatics, So I'm facing this rather strange issue that I haven't been able to diagnose 100%. It's an electrical fault where my Headlights, Turn Signal Indicator, Hazard and AC doesn't work all the time. Of course I did various tests on the Alternator. 1) Disconnected the + while...

    Hi everyone, Was taking my 05 M3 vert out for a drive today. Wouldn't say I was driving super aggressively but wasn't a stroll around the park either. Oil temp was about 210. I accelerated fairly hard, almost to redline, and all of a sudden the red battery light turned on solid. Immediately...
