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.

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.

ECS is my go to for anything BMW ECS is my go to for anything BMW. The parts are generally reasonably priced, some great deals come around, and you can get some really quality products. Their staff is ALWAYS helpful with questions and guidance. Never been steered wrong. I get parts for my 1985 535i, 2007 Z4MC, 2007 X3 3.0si, and the 2014 X5 xDrive35i - so their continued support of old and new cars is really important to me.

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
