Mercedes C300 W204 M272 ECU Repair Service

Hey Mercedes fans! If your C300—or any M272-powered Benz—is acting up, ECU Maverick is here to save the day. We offer a slick repair service for the Mercedes-Benz M272 Engine Control Module, specifically for the W204 C300 and a ton of other models. It’s plug-and-play, no programming needed, and we’ll have it back to you in just 3-5 business days. Let’s get your ride running like a dream again!

What’s Up With Your Engine?

Noticed something funky with your Mercedes lately? Maybe you’re seeing codes like P0050 or P0030 popping up—think alternator issues, throttle body glitches, oxygen sensor trouble, or even misfires. Whatever’s going on, just give us a heads-up about the problem when you send in your ECU. The more details you share, the better we can zero in on the fix!

Our Hassle-Free Fix

Here’s how it works: ship us your defective M272 engine control module, tell us what’s been acting weird, and we’ll handle the rest. No complicated programming—just a straight-up repair that’s ready to roll when you get it back. We’re talking 3-5 business days turnaround, so you’re not stuck waiting around. Plus, it comes with a 6-month warranty—though if something goes wrong, we’ll need a pro mechanic’s diagnostic report to swap it out under warranty. Fair deal, right?

Which Mercedes Models Are Covered?

Our remanufactured ECU works with a whole bunch of Mercedes-Benz models running the M272 engine. Here’s a rundown of some that we can help with: C230 (CL203 & W203, 2.5L, 2005-2008), C280 (W204, 3.0L, 2007-2010), C300 (W204, 3.0L & 3.5L, 2009-2014), C350 (W203, 3.5L, 2005-2006), and even the beastly C63 AMG (W204, 6.2L, 2008-on). But that’s not all—we’ve got you covered for CL500 (C216, 5.5L), CLK280 and CLK350 (A209 & C209, 3.0L), CLS350 (C219, 3.5L), E350 (W211 & S211, 3.5L), ML350 (W164, 3.5L), S350 (W221, 3.5L), SLK350 (R171, 3.5L), and tons more. Seriously, if it’s got an M272 engine, we’ve probably got it handled!

Check out a few more: CL63 AMG (C216, 6.2L), E500 (W211, W212, C207, 5.5L), E63 AMG (W211 & W212, 6.2L), G500 (W463, 5.5L), GL500 (X164, 5.5L), ML63 AMG (W164, 6.2L), R500 (W251, 5.5L), S63 AMG (W221, 6.2L), SL500 (R230, 5.5L), SLK280 (R171, 3.0L)... and the list keeps going!

Who We Are

ECU Maverick isn't just another ECU repair shop, we're electronics nerds who happen to love cars. We've been reverse-engineering, bench-testing, and fixing control modules that other shops call "unfixable." While most places only reprogram or swap ICs hoping to solve the problem, we go deeper: component-level repair. That means we can actually diagnose and replace individual circuits on your module's board, not just clone data and hope for the best.


We're based in Fort Myers, Florida, and we work with repair shops, dealerships, and vehicle owners across the country. Our specialty? European brands like BMW, Mercedes, Maserati, Ferrari, Aston Martin, Audi, Porsche, and Land Rover — but we also handle domestic vehicles, heavy equipment, and marine electronics. If it has a control module, we've probably fixed it.

What Makes Us Different

Speed. Most jobs ship back within 2-3 business days. Need it faster? Same-day rush service available.

Plug-and-Play. Every module we repair or program is ready to install — no dealer visit, no extra coding. Just plug it in and drive.

Real People. Text us right now and you'll get a reply from an actual human in minutes. No chatbots, no ticket systems, no "please hold."

Honest Expertise. We've invested years into research and reverse engineering. We don't promise miracles — but when others can't solve it, we often can.

Our Mission

Keep you out of the dealership. Save you time and money. Get your vehicle back on the road — fast, reliable, and backed by our 6+ month warranty. Whether you're a professional shop or a vehicle owner, we treat every job like it's our own car on the line.
