A large part of car culture across the globe is customization, especially so in America where it seems almost taboo to leave a sports car completely stock. Sometimes this sort of customization is crazy and over the top and sometimes it’s incredibly small and simple. What Nick Murray, whose has a popular YouTube channel featuring his car reviews, had done to his car is the latter kind of customization, as he’s had a few internal ECU codes changed.

If you’re not familiar with what these codes are, we’ll fill you in. Automakers must comply with many different regional laws and regulations across the globe. These regulations can consist of how bright headlights can be, what kind of interior chimes sound off for various reasons, what kind of legal messages appear on screens when starting the car and even some cool key fob commands. Different regions of different marketsĀ have different variations of these codes which allow the cars to meet regulations all over the world. If you can plug a laptop into the car and have the right software, you can change these codes to your liking. This is what Nick Murray gets done to his BMW M4 in his latest video.

So he takes his M4 to one of his viewer’s home, who happens to have the sort of software and hardware needed to change these codes, to change some of the minor things that bother him about his M4. Firstly, and most importantly, Murray has his LED headlight brightness changed, specifically the high-beam brightness. In America, LED headlight high-beam brightness must be toned down significantly from the rest of the world for certain regulatory reasons. Murray gets that brightness unlocked so the LEDs can shine to their full potential, which he says almost triples their brightness and makes a world of a difference.

He also has some more minor things done, such as allowing the windows to be rolled down remotely via the key fob, removing interior chimes when entering the car, removing the seatbelt warning chime when weight is on the passenger seat and various other little things which are listed on his video. So he doesn’t go too crazy, he just changes some small quirks that bothered him about the car, which just helps make the car better everyday.

These are great little changes that can really make the car yours and help perfect the driving experience. It’s cheap, easy and reversible, so if you ever want to sell the car afterward, it can easily be switched back to factory settings with just a quick plug-in of a laptop. According to Murray, it also doesn’t void the warranty.

So have you ever changed any codes in your BMW and if so, which codes did you change?

    I coded every BMW I have had since 2007, I drive legal disclaimer and backup camera warning are first to go, adding functionality to remote, open close Windows rear hatch etc adding digital speedo in the dash is a cool one and you can turn a lot of info on in the HUD if you have it. Newer f series cars have startup animations on the idrive screen and you can change it to rolls Royce or other BMW brands including m series and there is even a special winter theme one that has snow falling – pretty fun stuff to mess around with!

    I’m surprised he left active sound on. I saw you can even change the software to another car’s one… And that’s for every single engine that has this system of course (M5 sound in an i8 xD).

    I’m a computer/tech nerd, so things like this are awesome to me. A few years ago before owning my BMW, I purchased a popular OBDII cable for my Volkswagen Jetta for diagnostic purposes, which paid itself off after just the first use, as opposed to paying a dealer for a diagnostic and repair. That cable saved myself, and several of my friends, a RIDICULOUS amount of money because of how easy it was to plug it in and read your car’s fault codes right in your driveway, rather than spend time and money for a dealer to use the SAME software to do the SAME thing. Then when I got my BMW, I found a cable to do the same diagnostics (and no, my Volkswagen VAG-COM cable wouldn’t work – I did try though!), but I also had to purchase a special adapter that plugs in to the 20-pin connector under the hood for my particular E46 model. I later learned that the same cable can be used with free downloadable software to code and “customize” my BMW to enable or disable certain convenience features, just like what was done in this video. The things I was able to do using that software was AMAZING! I’ve never owned a car that was “customized” specifically to my liking. So, out of curiosity, I researched available possible options for my Jetta, and sure enough, I found free downloadable software for that car too, and I’ve been able to customize my Jetta’s features just like I was able to do on my BMW. It’s amazing that this is offered, however is a crazy huge shame that most BMW owners have no idea this is even possible.

    So, I’ve recently resurrected an old laptop computer running Windows XP to be used as my exclusive system for vehicle coding/diagnostics. Using an older machine for this purpose is actually better than using a newer one, as weird as it sounds, because the systems in these cars communicate and play nicely with older drivers which sometimes causes a problem on newer machines. I even bought a new battery for the laptop, so it can be carried around and taken places. I’ve done so much coding and diagnostics for many of my friends and family for free, which I know by now has saved THOUSANDS of dollars in dealer costs. It is absolutely, hands-down, THE BEST INVESTMENT I’ve ever made for any of my vehicles.
