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.
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. One of these sensors is in the active tank and could be associated with an malfuntion of emission system and emission violations which could render the motor to be disabled. Bmw claims that no recall on the issue has been recorded. I researched the issue to find that bmw has announced a recall on the scr system affecting the def mixer and the egr system. All of these issues will result in emissions failure and subsequent environmental harm.
Tire pressure monitoring start malfunctioning after 5 years.
Premature failure of diesel particulate filter due to malfunctioning emissions control system components, pre- and post- filter pressure sensors. The failure was a result of no active regeneration cycles due to malfunctioning pressure sensors that did not active fault codes until after filter has been blocked. I believe that this is a defect in the software programing of the diesel regeneration cycle.
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?.?.? This part has to do with emissions standards and due to the part being unavailable I'm forced to drive with a check engine light until the shop is able to get the part. Who knows what further damage this will do to the x5 and worst off, if I don't get this repaired soon, I'll fail a smog check and can't drive my car at all. I'm hoping the federal safety agency or epa folks can view this as a manufacture recall issue due to a faulty part and to meet epa standards....updated 11/13/15 *bf updated 1/4/2016
This car has been taken in 3 times now for the same issues. Engine light came on and smell of exhaust in cabin. This smell started at around 30,000 miles, but at that time it was minor, and would go away quickly. Exhaust filter cleaned at cost of $400. Next day the engine light and exhaust smell still there. Diesel exhaust reservoir and heater replaced (this was a recall for some of the same cars, but not my VIN). Cost of this repair $1,300. Five days later car taken back to dealer with smell of exhaust during cold starts was extreme in cabin. Exhaust levels measured and carbon mononxide in cabin at dangerous levels. Dealer says there are leaks in the exhaust at the engine and the cost will be around 1,100. Looking at postings on the internet, it appears there have been many issues with exhaust in the cabin , and with the exhaust fluid heater, and or cooler malfunctions. There appears to be a few recalls on the same year and model car exhaust and exhaust fluid components, but none on my VIN. This is a highly dangerous situation as the levels of exhaust in the cabin is at a deadly level. This exhaust level has been high enough to make me sick. This needs to be addressed asap.
Tl* the contact owns a 2011 bmw x5 diesel. The contact stated that while driving approximately 55 MPH, the engine malfunction reduced power warning message displayed intermittently as the vehicle stalled. In addition, the vehicle was over-consuming exhaust fluid. The vehicle was taken to a dealer where the mechanic stated that the problem was coming from the exhaust temperature control and the low pressure regulating valve. The vehicle was not repaired. The manufacturer was notified. The failure mileage was 98,000.
