Well, I should've done my research ahead of time...
2009 R56
I decided to delay my repair and order the ecs tuning red crossover pipe. I fought with it for an hour. Installed the thermostat housing and pipe multiple times, no matter what I did, the crossover pipe was too short to mate with the thermo housing properly.
I just happened to wonder... is it physically shorter?? Is that possible. Well, I compared it to the plastic one and it is indeed approx 5mm too short. F*%# !!
I looked it up afterwards and found a lot of people having trouble with the red version in particular.
Live and learn. Factory plastic it is ... 😞
