Three problems related to gas recirculation valve (egr valve) have been reported for the 2009 BMW X5. The most recently reported issues are listed below.
Egr cooler leaking soot/exhaust into engine compartment.
I bought my 2009 BMW X5 vehicle in June 2018, with approximately 61,630 miles and a limited warranty with �power train coverage�, which included �engine, transmission, front wheel drive, and rear wheel drive�. In mid-October 2018, my vehicle began showing the �low coolant level� light and �low oil level� light. I called the flow BMW dealership for service and took my vehicle in for service on 10/19/18. Flow BMW diagnosed a leak in the radiator. After contacting the warranty company (assure) the warranty company informed the service manager that they would not cover the cost of a new radiator ($1,300. 00) because it was not covered by the limited warranty under �power train coverage�. The radiator is one of the engine's unsung heroes. It's responsible for essential heat exchange functions in your car's cooling system. The normal operating temperature of the average car engine is around 190-210 degrees fahrenheit. With a defective radiator, the increased heat starts to wear on other engine components, and the resulting stress can shorten engine life dramatically. The coolant system is absolutely critical to keeping the engine running. This is a danger to the driver and to others on the road. The radiator issue and inevitable issue with the engine can cause serious injury to other drivers on the road if the vehicle's engine seizes are stops in the middle of traffic. After some research, I learned that other BMW customers have complained about the radiators in Bmws from the years 2007-2013 (documents attached). Again, the radiator is a vital part of ensuring that the engine runs appropriately, and if there is evidence of consistent leaking with BMW vehicles with very few miles due to a manufacturing error, then this problem should be corrected. Please see attached documentation for more information.
I am smelling extremely dangerous for health exhaust fumes inside the car while driving. The more the cabin heat is applied, the more exhaust smell is noticeable. I found many forums online related to the same issue on 2009 and up diesel powered BMW X5 xdrive35d. People are complaining about faulty egr coolers, leaking turbos etc. This problem needs to be addressed and corrected. Thank you.
