I am not looking to crack on this product, but since my professional install of this product on Thursday morning, September 11th, I have had nothing but problems!
Before you discount the quality of installation, the installer has experience as head VW mechanic and had an article written about him in a VW enthusiast magazine. He is very competent and skilled.
I had to return to my 2008 VW Rabbit 4d Auto/ESP two times the day of repair. First because of the binder clip and then because of a CEL.
The day following the repair, I had to return again because the nut that attaches the L binder to the fender bolt came off. I also had a CEL.
The day after, yesterday, I now have a CEL again.
