n00b with a X3 2.8i. timing chains and intercoolers
Hey all. First post, just signed up so I can do some searching around in old threads for some info.
I have a 2013 X3 2.8i that I got as a CPO. Fine car, works well, etc....but really regret not getting the 6cyl. That said, there are a couple things I'd like to improve. It's a U.S. spec, and I live in europe right now with sustained speeds over 100mph pretty frequently. I feel that after a little bit on the highway at those speeds, the 4cyl starts having trouble in the 100+ territory, and my suspicion is the intercooler getting heatsoaked. I'm not looking to make this thing a rocket ship, or mod the crap out of it, I'd really just like it to be able to handle the sustained speeds a little better. Are there any intercooler options that will fit this? I realize this isn't a boone of a performance vehicle for the aftermarket to grab up. Second question is timing chain failures....I've read a lot about this. So far, no issues. I havent noticed metal in my oil filters, and I'm doing changes every 5k with full synthetic 5w30. Was there ever an updated part that was fit to correct this issue on the 2013's? If so, how would I check? If not, how would I prevent it? I'm at 45k miles now, and have the 100k warranty. There has been some debate as to whether or not this BMW warranty is good at dealers overseas or not. I specifically asked about this when I got it, and was told expressly that it was, but subsequent conversations a friend had on their purchase has brought this into question for me....so prevention is the best bet to follow until I get back to the states in a couple years. I'm reading up about some updated timing chain guide parts that were issued by BMW, and it looks like the color of the timing chain guide is how you tell? If I dont have the updated, what can I expect to pay to have that done? I dont have the time, space, or tools required to do the job myself where I am right now. Thanks!....back to searching....

color of timing chain guide won't help. As new it's near-opaque white but as it ages/soaked in oil it turns to that orange one that you see in pictures online.
I'm also mulling eating the cost of a proactive timing chain replacement but have not seen anybody post details about it. I mean, timing chain is a wear/tear item on older vehicles, right? The only difference here is the failure is happening prematurely on N20s. |

I guess it could just be perception, as that is a funny thing, but it definitely feels like it starts to struggle after a bit. I dont have a diagnostic tool to track IAT, but that is probably a good thing to look at. About the only other thing I'd consider doing to it would be an air/oil separator system. |

hose and connector might need to be changed if you buy a kit for F series.
as for valve deposit.....remove the intake or use remote camera to inspect. I doubt you'll have any issues below 50k miles. |
