Review on BMW Engine Ignition Start Stop Button Replacement - Compatible With 1 3 5 6 X1 X3 X5 X6 Series (E81 E90 E91 E60 E63 E84 E83 E70 E71) By Jaronx Sports Red by David Perez

I was a little concerned about the quality of the plastic and paint, but I decided to buy it anyways. I was pleasantly surprised to see it was a good quality part. Light doesn’t leak through where it’s not supposed to, paint is well done and evenly applied, and the part fit well into the starter switch.There were no instructions for install but all you do is take the supplied clay, smush it on the current start stop button, pull quickly to remove, and put the new button in its place.
