Four problems related to timing tensioner have been reported for the 2009 Volkswagen CC. The most recently reported issues are listed below.
2009 vw Cc, timing chain tensioner causes timing chain to slip. . . Vw repeatedly told me the timing chain lasts the life of the car and there is no maintenance guidelines for the timing chain. They fail to advise/disclose/or suggest the tensions should be checked at any point. I have owned the vehicle since 2011 and have asked repeatedly during servicing for timing to be checked or if it needs to be checked and dealer never suggested that the tensioners should be checked as supposedly the timing chain should last life of the car. I took my car in today because the check engine light has been on every since they changed the spark plugs in my car and was told it will be $5300 to fix but suggested I just get a new motor. Why buy a used motor if this issue can happen again. Vw is aware of the tensioner failure and fails to even disclose to consumers that the tensioners should be checked in any routine maintenance or preventative maintenance schedule. It is implicity stated that the timing chain lasts the life of the car but knowingly and willfully fail to disclose that the operable parts the control the timing chain can and due fail resulting in extensive damage to the vehicle. My was taken in for routine maintenance and check engine light was on. If my vehicle had been in motion and the tensioner fails, the motor will immediately fail and coupd result in serious accident.
