ableseo Posted December 10, 2021 Share Posted December 10, 2021 Hi, I wonder if anyone could advise me regarding the attached video? I'm extremely new here and would like some advice. My Audi A6 2.7TDi has developed a loud ticking on and off during idle, the video shows two items simultaneously activating on and off continuously. I think these are the control unit for the turbo, and the other perhaps related to the exhaust gas recirculation sensor? This noise / action continues for a short time after the ignition is turned off. If anyone has any ideas on what is possibly causing this, I would be grateful for your input.

Steve Q Posted December 10, 2021 Share Posted December 10, 2021 Welcome to the forum you'll find the members on here are a friendly and helpful bunch ☺️ I'd definitely recommend a diagnostic check. But a common issue on this engine is with swirl flaps: https://www.audi-sport.net/xf/threads/audi-a6-v6-tdi-and-other-vag-models-swirl-flap-arm-and-butterfly-repair-kits.209136/ And here's info on c6 maintenance: https://www.audiworld.com/how-tos/a/audi-a6-c6-general-information-and-recommended-maintenance-schedule-423859 Quote Link to comment Share on other sites More sharing options...
