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.

Just bad customer service They could actually order the parts and not lie to customers. I called in to order my parts, The website and the representatives both said it that the parts were in stocks. Everything that I ordered was in and it should arrive to me within 2 to 3 days. A week later I called to check on my order because I can't even find the email for the order, to track when I called I was told no one but the representative who helped me place the order could figure out what happened to my order. I talk to that representative and was told "oh the orders out. There was a delay I should get my order in the next 2 days. After getting off the phone I magically received my emails with tracking numbers. Telling me the items were just labeled. I would have Appreciate it the truth better than a lie that was back up by your own system.

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.

Garbage parts Bad customer service Garbage parts. Defective and cheap spoiler. Looks like junk on the vehicle. If your past the return window good luck getting a replacement! Their lifetime warranty program is JOKE. You basically have to pay for the defective part a 2nd time to replace it and all they do when they get the part back is give you a in store credit. I will NEVER USE THIS COMPANY AGAIN!
