I have enjoyed Zippity for service in the past, but I feel like the diagnostic service this time around left a bit to be desired. I was really hoping to get some insight into a specific problem, and I am not sure that it was really commented on at all (power loss). Overall at least it was still very easy to use, but in the future I will likely need to explore other options. On a side note, it did not appear like tire replacement was still available for my vehicle (2013 A4 - located at Amica) as it was a few months ago? Update - The follow-up email from Nico clarified my questions and also noted that tire service is available - Great job!
