Okay, now back to the good old problems. First: the engine.
Problem #1: Fault code P164C00
I still get the P164C00 fault from time to time. It reports a Implausible Signal from the Oil Pressure Switch for reduced Oil Pressure. And I still don't really get why. The only consistency I noticed is the appearence of this fault after an engine start (both with the key and the start-stop-System).
I changed the actual reduced oil pressure switch. No difference.
I changed the high oil pressure switch (since it is a reference value to the reduced oil pressure switch). No difference.
I changed the oil pressure regulator valve (since I read somewhere that it can cause this fault). No difference.
Then I fiddled around on the connectors of all three parts. After that, the fault went away for some time but now shows up again irreguarly.
Another noticeable detail: Sometimes (not always) my car would throw an EPC warning at about 180 km/h under accelleration. Afterwards it would report a malfunction of the high oil pressure switch.
Also a noticeable detail: I recently checked the oil level. It was about 1 liter short of the maximum mark, aka just underneath the minimum mark. This seems odd to me since I did an oil change about 100 km after the engine swap and filled it to the correct level. Now I have spent my entire 5l jug of oil.
My guess (which is ignoring the mysterious loss of oil) is an improper electrical connection of the connector of the high oil pressure switch, so that sometimes it doesn't deliver the expected value to the ECU for really short periods of time. Short enough to not be noticeable when live montioring the values of the switches with VCDS. Does that make sense?
Problem #2: steam/smoke (?) out of the exhaust
Now that it gets colder I noticed excessive steam out of my exhaust. Sure, when the car is cold thats completely expected. But I also noticed it after about 10 km of driving. It doesn't smell like smoke or gasoline (the latter only after cold start), rather a little bit like a cow pat. Don't laugh, please! XD
I don't seem to loose coolant, so I would rule that option out. Might it have something to do with my mystery loss of oil I mentioned above? Or might it be faulty injectors (I only cleaned them in a warm ultrasonic bath with injector cleaning solvent so they might still be bad or clogged up)? Or is it completely normal?
Problem #3: ALWR control unit
As I mentioned before I installed a used 6R0907357C out of a passat CC with xenon. I did reset all adaption values and did the basic settings for the head lamps. There are no ALWR related fault codes anywhere. Either way, I cannot change the coding to Iichel's example. Whatever I try, the first byte is always "out of range". Also I am not sure if the adjustment of the headlights actually works. Is there a value in the adv. measurement list that helps me out? Do I maybe have an incorrect sensor at the back axle (Right now it is 6R0941273B)? Or will everything be rectified by the new parameters by TinyQ?
Thanks in advance and sorry for that enormous amount of text!

the installation of LED headlights on 6R (europe, etc.) would not be so charming.
