    My car has an issue whereby the alternator will not run at all at cold start, however after setting off or even revving the engine to around 2k rpm it will begin charging. This is accompanied by a rough cold start where the rpm's sort of swing up and down and the car feels like it will stall...

    I'm currently in the process of fixing a very lightly damaged M6 and want to get to the bottom of some electrical related codes stored (shown below). As you can see, these codes specifically relate to increased battery discharge and alternator issues. When the car first arrived to me the battery...

    Hi Everyone, Does anyone know if there are any wires in the mirror/map light area that are ignition/accessory controlled? I would like to find a power source that can power a radar detector that will be ignition controlled. TIA Rich Wong

    it is not a real big deal, but being OCD I am trying to fix this: I have been observing that the power steering reservoir keeps leaking oil through its cap. Tightening the cap does not help. I noticed that there is no gasket on the cap. Looking at realoem.com I saw that there is a rubber gasket...

    Thanks in advance for your help! I opened the garage door on Saturday evening and noticed that my tail lights were flickering on/off. I hadn't driven the car in 5+ hours and am 99.99% certain that I turned the car off when I parked. When I tried to open the door (and trunk) the comfort access...

    Hey guys!:byee55amg I'm pretty new to the forums and to the E39 M5 I have owned many bmw's and so far sticking to the brand! Right off the bat I'll let you know that this isn't a crazy horsepower build, or any unique build projects. My biggest project was my e36 Active Autowerkes...

    So this car has had its VANOS units replaced along with both IONIC sensors (after all 10 coils showed misfire errors) and the pressure accumulator. It went in for the VANOS job after some time with very poor idling and engine performance and having it checked with Autologic it was done. Drives...

    Hi everyone, I'm looking to purchase a 2003 m5 before the fall but i want to give it some more power. So I would like to know what you think is the best way to get the m5 to around 450-500 horse power. Ive been doing some research on aftermarket parts and so far a performance chip and a new air...

    Ok, so I need a car for the winter and sadly the insurance on my M5 is a bit high so I'm going to sell that. I've been looking at 335xi's because it seems to be the best option but I still have a few questions. The vishnu tuning seems to have a huge impact on the power but beyond that I don't...

    1. Looks I had the car shipped to me and picked it up a few weeks ago. The body is in excellent shape and the wheels perfect, the car looks amazing in person. The interior is also in excellent shape without a single scratch on the leather or plastic panels and trim pieces. I popped the hood...
