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.

Great Customer Service Had an issue with wrong rotors and ECS made it right without me even asking. Their selector showed rotors that did not mention vented or not. When I received them and took my mine apart mine were vented but 5he ones ordered were not. I called up and they said, don’t worry we will get the correct ones to and they did.

Worst company ever , DONT BUY ANYTHING Worst company ever Should be out of business Worst customer service in history Waited over 2 weeks to receive the wrong part Then another week or so trying to talk to somone in there customer service team (they dont answer the phones or email back) Its now been over a month and i have had to fix there mistake myself I dont EVER write reviews EVER unless im that satisfied with customer service for example ARM is above and beyond with there customer service and shipping speeds I went ahead and made this review to show how awefull they are Im that mad and dissatisfied that i wrote a review on every single option to leave a review on This is beyond a disgrace of a company

superb as always i have been using ECS for years and they always deliver quick and a very friendly staff. I have never had an issue with any orders and all the parts were as described.
