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 need to get myself a new battery shortly and just wanted to see what people recommend for a car that will mostly only be used on weekends. I know the factory battery was an AGM but I hear these are not good if the car only sees occasional use, and are better suited to daily drivers. Is this...

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...

I'm shopping for a battery and have questions about a couple of matters: (1) Can I do it myself? I am not a backyard mechanic. My on-line research seems to indicate that it's a straight-forward, uncomplicated process. But the product descriptions of those brands available from nearby retailers...

Hi all, sometimes my 2009 E63 M6 does not engage reverse gear and wont show R on the dash if I select reverse straight after turning the car on: even with the gear stick in R, it just shows N. I can get it to engage reverse by going from N to D and then across to R, and then everything...

Good people of M5 board, I'm the proud owner of an '01 beast (135k mi) that I keep in an attended/valet parking garage near my apartment (can't stand other people parking the car, but the joys of NYC living). I bought a new battery about 18 months ago, and a few weeks ago the jokers in the...

Help! I had Charing issues some months ago and took to shop. Battery wasn't getting a charge and volts would fall below 11v while driving....Replaced Bosch Alternator and Battery. Everything fine for 4 months. Red Battery Lite came on and Battery Test 09 saying 11.5v and drops down to 10v...

Board, I need your help. I've combed the boards, read up on the how to's and even done a little coding and changing of the VO. I replaced my battery today and thought that it would be a walk in the park to register the new battery. I've got a 2006 that was born in the notorious month or...

I am in the process of repairing my E39 M5 from a collision to the front. The BST battery safe terminal on the positive battery cable connected to the battery has been deployed, leaving me unable to start the car. I want to know if there is a way to delete the BST and connect the positive cable...

Hi all. I have a real headache with my 2001 e39 M5 which I have owned for nearly a year now with no major problems. A couple of weeks ago out of the blue my car wouldn't start, engine wouldn't crank over at all. Called my breakdown company, they sent one of their senior mechanics out and he...

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...

My first post woot! :) So anyways, My 2007 E63 has this issue where after sitting for a day or two it does not want to start up right away. I can here the fuel pump prime and all but when I get the "start" button with my foot on the brake and in Neutral just does not turn over. After turn it...

I have been getting the high battery discharge message after a long stop. I have a new battery, new IBS cable, checked the alternator and everything seems ok. Seems like the car is not in full sleep mode. After switching off the car, after some time the dashboard comes alive with the letter N...

I thought I would throw up a quick post about the battery going bad and I had my car towed (flat bead) to the the dealer and now my car keeps throwing the red cog. I took my car back next day because it was throwing the red cog error (4-5 times per mile) around town. Dealer called to say they...

Hey guys, My stock battery is completely dead :1zhelp:. I believe it is the 90 amp version which is non AGM. I purchased this today: AutoCraft Gold AGM Battery, Group Size H8, 900 CCA-H8-AGM - Advance Auto Parts The dealership told me that I would need sort kit to make the battery work/fit...

Before I start, I know this is no M5 but I'm looking to get any help wherever I can. I've been fighting a power drain for a few weeks now. It's enough to kill the battery in under 12 hours. I'm having some trouble with my AC system at the moment, so I unplugged my FSU in case that was the power...

Hey guys, Here's the deal. My car has been sitting at my Dad's house for about a month, and when he tried to open it up today, nothing happened. According to him, he can't get the car to do anything with the key, including opening the door manually. At first, I just figured it was the car...

A few years back, when I was still under warranty, I had the service department at my local dealership replace a faulty battery (along with a bunch of other items). Much time later, I happened to notice that the cover over the battery compartment, which is normally secured using 3 brass flange...

Familiar story: I left the lights on all day at work and found my M5 unable to turn over. I proceeded to jump start it via connection in the trunk but in the process some sparks flew and "something" blew/went out. I say this because when the sparks flew the lights in the trunk went out. I...
