Two problems related to timing tensioner have been reported for the 2011 BMW X5. The most recently reported issues are listed below.
The contact owns a 2011 BMW X5. On several occasions, while driving and idling, the contact heard an abnormal noise coming from the engine. There were no warning indicators illuminated. The vehicle was taken to a dealer where it was diagnosed that the engine belt tensioner needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the issue. The failure mileage was 65,000.
I received a noise from the engine and started an alert on dashboard engine malfunction reduced power drive safely to the BMW dealer. BMW dealer looked at the vehicle and suggested to change engine oil, solenoids, belt tensioner and deflection pully, however the engine sound did not go off. Now they asking me to change the engine and turbo. The only service did earlier was the vanos gear bolt recall. Dealer and BMW na says it's because of aftermarket oil filter. I think aftermarket oil filter damaging the engine is irrelevant. I think there is a serious problem is getting hidden by BMW. Can anyone please help.
