Fuel Injectors in N63 engine

Sorry if this subject has been covered but here goes: I've had my 2010 GT for 2 years now, a dealer loaner (had 23500 miles on it). The only problem is consistent: multiple changes of fuel injectors, about every 6 months. The car goes into a slight to moderate shaking mode when this happens. I don't get it. The service manager kinda expects it when he explains that these engines are very sensitive and performance oriented. After flying airplanes for 39 years, I can tell you that if this happened once, the airplane would be grounded until they found the source of the problem. The only advice I was given was to use high test gasoline (that I have never varied from) and from a specific brand (Conoco and Shell in Colorado). This hasn't seemed to affect the engine to prevent the engine monitor light from coming on and causing shaking/vibrating. I don't know what to do. I even wrote a comment on the Cars.com website about how great this car was (from about 2 months after owning it). I even got to see the maintenance history at the dealership on the car the day I bought it, and it was clear except for the normal maintenance. I'm now looking to get rid of it and get a more reliable car/suv: infiniti FX, Acura MDX, etc....I can't afford $800-$1200 every time the engine needs this kind of work when the warranty runs out (I have a certified car, so the bills are paid for by the dealer). This is my 4th 5-series BMW and none of them had had any engine problems like this.

This is the problem with auto dealerships...they only replace the symptom and perform the quick fix. I blame the lazy/cheap consumer for allowing them to get away with this. Obviously it is a problem as you are not alone. The most annoying aspect is that some of us don't experience these symptoms so it is clearly not a design flaw.

I wanted to address the bolded, blue statement: "Dad...is that you?!" This is something my father has stated many times in my life and the only logical response I can think of is:

The airline has corporate liability and the dealer thinks it is wise to pass the responsibility to the consumer since if we find a litigious situation as a class we're going against BMW and not the dealership so they are always "safe".

Unfortunately the only way we (as a consumer group) could solve this is to develop a site/sheet containing the vehicles exhibiting this problem along with their manufacturing date and VIN. Only armed with this information could we then identify whether there is a trend in the manufacturing process, a secondary part supplier, etc.

Right now all we know is that it occurs much to frequently and is not a BMW exclusive issue.

Sorry to hear about your experience.

The updated fuel injectors have been around since approximately January 2013. If they are still replacing multiple sets, something else's is going on and they are misdiagnosing it.

THere's no shortage of threads on this issue with 550 F10s (5 series sedan) as well. Walnut blasting the intake manifold is a common cure.

Here is a great thread with some good info. Considering purchasing the thing as it appears it pays for itself after one use...

Home run on finding and posting the above Daders.! The terminology of walnut blasting is clarified when you see the photos before and after.
