The stubborn 'check engine light of doom' reared its ugly head once again, but service was postponed because it was directly related to Audi's horrible B7 platform Turbo design. However, the 'EPC light of oh ****!' burst out of the dash like a supernova. A turtle could have traveled down Ala Moana Blvd. faster than my car. Generally, the EPC light turns off after a restart, but it didn't this time. Panicked, I immediately called Barbara hoping Honolulu's "finest" wouldn't cite me for using my cell phone with the key still in the ignition. Barbara scheduled an appointment for me to take the car into WW the next morning. Thankfully, the hellacious EPC light turned off after waiting 15 minutes and I was able to park Ms. A4 in a safe place. The Next Two Days: WW immediately identified issues by checking Ms. A4's Deutschetechniksupercomputer, recommended appropriate service, and performed a requested routine oil change. Unfortunately, WW had to babysit Ms. A4 overnight because I was no longer in Honolulu. I picked up Ms. A4 the next morning and WW helped me prioritize future service visits, ordered parts, and scheduled a future appointment to address priority No. 1. It was your typical mid-day in paradise where AC was definitely needed, but it was kaputt. Ironic because Ms. A4 was blowing air almost as cold as the summit of Mauna Kea on a summer's day on the morning I dropped it off. I called WW, left a message, and took Ms. A4 back to the shop without an appointment later that afternoon. The technician checked der Deutschetechniksupercomputer once again, but the solution was much more simple than that. WW fixed the problem, on the spot, no questions asked, kostenlos. Patience is a virtue. A special mahalo to Barbara, Rod, Frank and Lance for their continued "service with aloha".
