I was a bit nervous about ordering an ECU online, but this 2013 Mercedes S350 3.0L AT diesel ECM arrived quickly and was already VIN programmed, which saved me a ton of hassle. The team kept me well informed throughout the whole process, answering my questions promptly and clearly. Installation was straightforward since it was truly plug-and-play, just as promised. Shipping was also surprisingly fast and reasonably priced, considering the size and weight of the unit. After swapping it in, my car runs smoother than ever, and I couldn’t be happier with the service quality.
