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.

A very satisfied customer Placed an order through customer service. When my parts came it was the wrong parts. When I called to explain, the customer service representative was incredibly helpful and corrected my order and sent the correct parts at no cost to me. I cannot go wrong ordering parts through ECS. They're experienced, courteous and always willing to make their customers happy.

Bought coated rotors that rusted in 6… Bought coated rotors that rusted in 6 months, In order to get a refund I need to purchase another set from them , I told them I would send them back and if they can return my money? Th Amanda there customer service manager, stated the only way is to repurchase again from them and they would issue a credit . There "HOME OF THE LIFETIME REPLACEMENT" IS A COMPLETE SCAM! I'M AFRAID IF I DID SEND THEM BACK I WOULD NEVER SEE MY MONEY OR CREDIT FROM WHAT I'VE BEEN READING ON ALL THESE SITES THEY'RE A FRAUD AND I NEED TO BE STOPPED!

How do you get to talk to a real person? UPDATE! Parts arrived in a timely manner and were well packaged. Unfortunately, the exhaust support, which is rubber, was already cracked and broken. Haven't called to replace it yet due to having to buy the replacement and receive credit due to it being a "lifetime warranty part". Just tried to call to straighten this out before leaving a review,but it tells me "how to do a return online" Need to speak to a person, not a cheery, robotic voice that tells me nothing useful! UPDATE: Heard from ECS and they are sending out a replacement part. Throws off the timing of the work a bit, but they made good. Stars updated.
