“Found this company online. I tried everything to get my 2002 C240 to work aside from messing with the ECU. As a last report I sent them the ECU. Within a few days they had fixed and sent back the ECU. The car works great. I paid $299.00 in total!!!! I spend just as much for a new battery. I’m still in amazement over the price and the professionalism with this company.”

“The ECU Pros did a great job diagnosing and repairing my 2008 C63 AMG ECU. Total turnaround time was about 2 weeks including shipping. They even included a video of my ECU running another car to verify that the repairs worked prior to sending it back out to me.”

“I sent my Cascadia DD15 ECU to The ECU Pro after the truck had problems with the cruise control and the dealer quoted me a crazy price. They diagnosed and repair it over the weekend ( send it in Thursday afternoon, by Tuesday I had it back). Plugged it in and the truck fired right up, no issues at all. Great communication and way cheaper than replacing the whole unit. Definitely recommand The ECU Pro if you've got ECU problems on your Freightliner.”

“I sent in my ECU with instructions to repair or replace if necesarry. They tested within a day of receiving it and found no problems. They took a video of my ECU in their BMW which showed the car starting and running. I appreciate that they didn't "find" problems that weren't there. I got updates from them at each milestone. I also ordered a duplicate key which is genuine BMW. Just under 2 weeks from shipping it out to receiving it back. These guys are among the best specialty repair shops I've dealt with. I highly recommend!”
