Just bought a 2010 550i GT (with 4.4L N63 Engine). I have a few questions on injector problems with others with the 50i engine.
It is CPO until March 2016. Ran fine first few days but then hesitated starting. Took it in. They claim it needs all new injectors. Did some research and that seems to be a common issue with the N63 engine. I then ask them when/if they were ever replaced before. They said they've been replaced several times, most recently 8 months ago. Needless to say, that was pretty alarming... only 8 months and it needs ALL 8 new injectors again? In discussing it with my SA, he said they need to do all 8 because this is a new injector design. So that sounds fine... but in doing further research it seems there has been several revisions to the injector design since 2010, but that the most recent design was longer than 8 months ago (like 2013). If so, why would they have put outdated injectors in 8 months ago? Or has there been another revision since then that I haven't found?
Then, SA calls a couple days ago and says "I don't want to blame anyone but it looks like the dealership that previously installed the injectors messed up a mounting hole for the injectors, and will need to be fixed." Then he goes through how he will need another two weeks etc, etc, but was being very cautious not to tell me too much. He wouldn't tell me exactly what hole was messed up, or how badly, or how they would repair it which I found odd. So, I go and talk to the salesperson and ask if she can get anymore info on it. Well she comes back to tell me its an issue with the cylinder head having a stripped out bolt, and that he was being hesitant because a BMW warranty rep has to come look to see if it's covered. She then explained that they can "refinish the head" or "sleeve the hole and tap it again." Can someone help me understand what may be going on here? I'm worried that either of these "fixes" may compromise the longevity of the engine... I mean a repair like that the engine is never going to be 100% again will it?
Also, in my reading I found on the BMW website that all repair work is covered for parts/labor for 2 years when done at a BMW dealership. When I asked my SA he confirmed this is true, but was unwilling to put it in writing and had nothing to give me proving that. My concern/question is: does the 2 year warranty only apply when it's a consumer paying for a repair, or would a CPO warranty repair also extend 2 years from time completed? It's important for me to know because with these injector issues it looks like I shouldn't keep it much past the warranty period and this will make the difference between being able to keep it 1.5 years and keeping it 2 years.
