My son took my rs6 c6 into carillon services today for pcv valve renewal. They where very friendly and informative. They picked the possible issue of the pcv valves over the phone and was verified on inspection ive got old part to verify. All so picked up that my valve stem oil seals need changing. Thanks to cory and his technicians our oil burning issues have been solved. The car had just come out off mrc after 14000 spent n they missed these issues. I'll be using Cory n his company from now on. Thanks lads 👍
