Don't rely on ECS Tuning application guide Based upon website guidance, I ordered an auxiliary input wiring harness for my 2003 Mercedes C240. I received it, decided to do some online verification before opening the package. I learned this harness wasn't compatible with my car's wiring. After a lot of hassles I was authorized to return it. I paid shipping both ways for a part incorrect for my car, despite the website claim it would work.

Why is ECS still in business? Can anyone tell me why this company is still in business? I'll spare you the details of my story with ECS except to say they have no customer service at all. Further, I twice spoke to their sales person who twice forwarded my call to never answer customer service. His name is Michael. I'm considering filing a civil complaint. Obviously they know about their poor service but have chosen to do nothing about it That helps justify punitive damages in a law suite. What do you think the jury will think about all these reviews?

Great Customer Service Purchased some amazing well built items for my MK6 GTi i had some issues with the parts that I had ordered. Upon installation these parts didn’t fit , and after a lot of emails and pictures as I am based in the United Kingdom , the customer service team did their best to help come up with a resolution and will happily recommend and purchase from again. Keep up the great work
