I just used a scribe/pick tool to fish them out. Didn't take much effort. Feel free to pm if you need any more info.

You are correct. I tried using the tool to install, but was way more cumbersome messing with 2nm counterclockwise with a crows foot. I just made sure they were seated and flush. The brackets do a good job of seating them down. I was just really careful and checked for leaks.

Yes. Reset all adaptations after registering injectors.

From what I've read, it only applies to vehicles physically in North America. I'm currently over in Italy and dealing with BMW dealership over here is a huge waste of time and money. Brought my car in once, they had no idea what to do. Spent more on a rental car (no loaners here) while they troubleshot. Rather than trying to save a buck, I went ahead and fixed it myself. |

I will note for anyone that suspects leaky injectors, upon replacement, DON'T FORGET TO CHANGE THE OIL.
If there is any suspicion of fuel in the cylinder, you can bet it's made it to the sump. It's not worth it, spend the extra $100 when you order parts and change it. |

UPDATE: After 2000 miles, finally got a CEL and same 118111 code came back. No DTM. Pulled plugs, no wetting and they look ok.
Then went to looking at the downpipes for any sign of leaks. I don't have access to my local shop's smoke machine since everything is still closed here in Italy. Here's what I found. Noticed a huuuge gap on the clamps. Not sure if that could be a cause for any leaks, but it seems to be pretty clean and dry so far. I'll take a deeper look when I get home tonight. Will also remove/inspect/clean both MAFs as well. Anyone have any other suggestions? |

So highly suggest you to look at voltage graphs of all 4 o2 sensors on ISTA+ |

mine's looks like this:
See how the line fluctuates badly. When we saw the graph, we were pretty sure the post cat o2 sensor's gone bad, since the pre cat o2 on the same bank read normal (red line and orange line overlaps on the graph, glad to see that ) btw, my faulty o2 doesnt constantly give wrong voltage, that's why it doesnt always throw rich mixture code |

What version of ISTA do you have? Mine seems to be an earlier version. |

For your case here, I’m not really sure if faulty o2s cause both pre cat and post cat below limit. For heating up o2s, I would try to drive around for a while first and then perform the check operation. Then try to swap o2s on both banks to rule out o2 failure. |

Only bad part about living overseas. Min 2 weeks for parts from the states. I'll also look at updating my ISTA. |

Swapped post cat O2s left to right, and ran tests. No change. Still fails to heat up both lambda probes on bank 2. Other than updating ISTA, I'm kind of at a loss. Don't know where to go next.

The lambdas should heat up fast because they are fitted with a heater to speed up the process. Either both sensors are bad or they're not being controlled.

Installed the latest version of ISTA I could find (4.22.13) Ended up having to reinstall windows to get it to work.
Anyways, it was able to get past the O2 warm up phase no problem. Here are the results from the tests. Bank 2 post cat is spiking. But this is after I swapped around left and right post cat sensors. In between tests I swapped around the MAFs as well, no change. What would this indicate if we can rule out the sensor being bad? Seems to me like it's actually reporting the problem not being the problem itself? |

Looks like you could have a bad cat on bank 2 as the post cat sensor appears to be slightly switching rich to lean. Check for any leaks between the pre and post cat sensors although this is unlikely.

Thats what I was thinking too. I still have the original cats. Might try to swap them in after the engine cools off.
