Let me start out by saying that this article is very subjective. Each M5 owner has his or her own expectations for the car. Some people are after pure performance, while others are allured by a refined, quiet luxury car that also has balls. Many of us are somewhere in-between. I bought my 2000 M5 in 2010. It was my first car, I was 17 years old. Somehow, I didn’t kill myself. By 2011, the void of E39 M5 DIY content online had pissed me off enough that I decided to spearhead the lack of online content with E39Source. This has allowed me to connect with hundreds of fellow E39 (M5) owners. I would never say that I have seen it all, but I have been exposed to a lot of very tasteful (and garish) mods. In this article, in no particular order, I will list and describe several ‘must-have’ modifications, per my taste. Continue reading
Let me begin by saying that I may be slightly biased when it comes to my assured claim that the E39 M5 is the greatest sports sedan of all time. While there are many other remarkable performance sedans out there (E28 M5, E34 M5, W211 E55, C5 RS6, and countless others), the E39 has held a special place in my heart from a young age. Not many other sedans have aged as gracefully and the E39 M5 represents the perfect blend between past and present in the M5 lineage. While its performance is not as remarkably impressive by today’s standards, the E39 M5 blends the right amount of driver involvement with refinement. Continue reading
Hey guys, thanks for letting me join E39source! I’ve been a YouTube subscriber for quite a while now, and actually met some of you at the Pittsburgh Vintage Grand Prix last summer. My name is Mike, and I’m 25 years old and live/work in West Chester, PA. I currently have two E39s: a 1997 528i, and a 2000 M5. Continue reading
I just bought my 98 BMW 540i 2 weeks ago, and I knew when I bought it that there was a check engine light on for an EVAP code. I pulled the code and it came up as P0443. I just wanted to outline a short diagnostic checklist of things to check when you experience this or any other EVAP code related to the purge valve. Continue reading
In the past few years the N54 twin turbo 3.0L Inline-6 has gained the reputation of being an easily tunable and powerful engine. With the N54 aging and the increasing number of modifications available, we are bound to begin seeing more blown engines and turbos. Although the block and internals are very strong, the N54 is prone to issues without the proper maintenance and repairs. Whether your N54 is stock or running a large single turbo set up, this guide will ensure your engine is running at its best.
With this modification, your M52B25 or M52B28 engine will make more power.
The M52B25 and M52B28 engine can be found in the E36, E39, E38, and in some early BMW E46 models. It is not the easiest modification, but if you are at least a little handy, it is not difficult. Some people say that this will gain an additional 20HP, while some say it won’t give you any. I believe that there are power benefits.
In the picture below, you see on the left an M52 intake, and on the right, an M50 intake.
My name is Diederik, 21 years old and I am a mechanical engineer student with a passion for cars. When I was searching for more information about the BMW E39 M5 I found this website and registered myself for the future.
At the moment I drive a BMW E36 323i MT coupe in Hellrot with some modifications and a Volvo 855 Turbo AT in Beige Metallic. Continue reading
Hello E39Source. I am a new member to this website, and I wanted to get more involved with this close knit group of E39 enthusiasts. I just recently purchased my first M5! I bought it in Seattle, Washington with 148,000 miles on the clock. Continue reading
My past BMW’s were fun cars. I had a great time driving them, and I learned a lot fixing them. However, they got a bit repetitive after having cars so similar: the E53 X5, E36 318ti, and the E36 328i. These all shared so much in common that I could go through the motions to change out a thermostat or replace an oil filter housing gasket with my eyes closed. So, what does a car guy do when they need a new project to tinker on?
He moves on and gets a 1995 W124 Mercedes E320!
Easy, peasy, lemon squeeze: all you need to do is retrofit your stock plastic lens E36 headlights with bi-xenon projectors. With some modification from a Dremel, razor blade, and a pry tool, you too can have HID lighting without resorting to a eat-ramen-every-night college-esque budget. Continue reading
