My service engine light came on and time was of the essence to get it diagnosed. Pro 1 was busy on the day I took it in, but they jumped on the service, replaced a glow plug and cracked turbo boot, and had it ready for me the next day. Great effort! The only reason I did not give a 5 star is they were reticent on calling me back and keeping me up to speed on the status. Minor issue, but made it difficult to plan for rides home.
