Concerning the 2 first ones, is somebody able to give me the exact references to order ?
On the BMW ETK, I found only one sensor before cat (ref : 11787831624) and 2 after cat (ref 11787832035 + ref 11781405324). Problem : I can not find which ones are linked to the cylinders 4-6.
So : For cylinder 4-6, could you tell me what are the both exacts references of sensor ? Due to the price, I need to be 100% sure before ordering.
Concerning the third line, I do not understand well why I have this problem. What is the piece to check ?
I looked the device who turning the flap (ref 7511383) but did not found any trouble with it.
Any idea for this line ?
Thanks for your help

Presuming your car is LHD (shouldn't be any different to the RHD model)
before Cat cyl 4-6 - (935mm lambda) - item 2 below part number 11781406622
post Cat cyl 4-6 (750mm lambda) - item 10 below part number 11781405324
The intake manifold switch flap is item 3 in diagram below: part number 11617511383
Use the GT1 to test the flap operation - there's a function in the expert menu to do that (you can open and close the flap on command). It could be an old fault and somebody's replaced the flap but never cleared the codes - when you scroll through to the next screen on the GT1 it should tell you if the fault is present or not - if not, just clear it and check that flap operates (sport mode on - rev in neutral to about 3800rpm and get someone to stand in front of the car to see if the flap opens)
