Dam, I should have copied all those pages. Sorry.

Here's what I recall.

The two engine ECU's (one on each side) have coolant lines going to them, and they are apparently not flexible. So you need to move these out of the way. On the passenger side the Reservoir for the coolant has to be moved out of the way, the manual I believe recommended removing it, but my tech was able to move it without removing it completely. Those are the two items that are a bit of a pain.

For the plugs, BMW strongly recommends vacuuming out the tunnel of each plug before removing a plug. Carbon deposits can end up in the engine otherwise. I did my Q7 a few weeks ago and did this, I didn't see much debris in there, but I could imagine this being a problem.

The coolant line thing is what threw me off and said this time it's on BMW. I will eventually be DIY this for next swap but hopefully someone will have a good video on it. Or I'll make a shitty video on it.

Mike
