Update - July 2020. No longer works, warranty expired. Bought in 2018. It's been about 2 years. I had a leek in a hovercraft so it expired more than intended but never stayed easy. There was a very slow leak. So I lived 2 years. The best thing you can do is get rid of the Audi if you have one. Complete garbage. Replaced an '08 Audi A8L with this because my bleeder valve was stuck causing it to get stuck in lift mode. Has been around for about 2 months. So far, so good. It's louder than the OEM but costs $1,350 less. I can live with it. Sounds like any other small 12 volt air compressor. I've never heard OEM, but I certainly listen to it when I'm on the road. For the price I can live with that.
