2011 BMW X5 Diesel SAV Engine Problems

“My wife was driving on the expressway with speed limit of 50 miles / per hour. Suddenly the car showed engine malfuction - power reduced and she couldn't keep the speed and car starting losing speed and dropped to 10 miles / hour, she had to pull off the road to avoid the danger of being hit by other cars on the busy expressway. After she pullled over and called me, I drove to the place where she parked the car and used a code reader to found some error code 47c4 , but after restarted car, car seemed ok. …”

“I have a 2011 Bmw x5 335d with a little over 73k miles. Just recently my check engine light came on and after a trip to the shop the techs said it was due to a faulty def (diesel exhaust fluid) sensor. Unfortunately this part is ~$930 and is on a national back order. I asked if the part is a manufacture recall, but it's not. I'm mind boggled because I had the EGR replaced twice under manufacture recall free of charge, but this def sensor isn't. How can this be?.?.? …”

“Recently purchased 2011 Bmw x5d. Vehicle had 147, 068 miles. After driving at highway speed for less than 100 miles from the purchase point, cel came on. The seller was notified only to tell me that a sensor reading needed to be checked and the vehicle was fine to continue to drive. A week later a certified Bmw mechanic informed me that the diagnostic reading indicated nox fault 4bfo. Reducing agent active tank sensor signal 4bac. Throttle valve actuator 4687. As well as 3 other faults relating to these. …”

“I received an engine malfunction reduced power warning on my vehicle. When this happens I loss power an cannot go over 20 MPH. I was on the highway when this happened .I took it to the dealer and found out that it was an EGR and vacuum line problem. Doing a simple search on the web thousands of other x5 diesel owners are experiencing the same issue. I contacted Bmw north america told them of the issue, after a week they got back to me and said the parts were not covered even though they get many complaints.”

“Our Bmw x5 diesel had a recall done back in 2012 for EGR valve being faulty. Bmw's emissions are failing on their 2009-2011 diesels. We recently dropped off our Bmw x5 for service and for another recall, discovered Bmw will not cover their fault part this time around. They have a bad design with the EGR's and they know it, that's why the recall was done before, now the recall part failed. They want us to pay for it. They are not treating this issue with much attention. Our engine is going to fail because of this recall. Dont know what else to do at this point.”
