Kaj,It is hard to confirm anything if you have 1/2 of oil pan wet. I would wipe it off and wrap paper towels around the hoses and whenever you can stuff it and recheck after short drive.
The stuff looks redish, so the pictured ATF piping would be my suspect.
Have you tried replacing the oil level switch/sensor? MB did an inspection on my car and said that I need to replace the sensor, just waiting on the parts. I'll keep you posted after I installed it. I might also do a DIY with photo.Kaj,
I have the same oil leak at the same location, and also I can see some oil drop at the clamp that is attaching the transmission pipe to the oil pan, can this pipe break at the clamp connection?
I wiped it dry before but It is really hard to tell where the leak is coming from, and in my case It does not look as it is ATF cuz the color is more brownish than red and the ATF is new.
I have no errors regarding the sensor but I did read some threads regarding leaking oil level sensors. So I'll replace it by myself when the part arrives.Sensor replacement on V engine is major job. My friends have defective sensor but after getting estimate for replacement 3 years ago -decided to deal with errors coming on the cluster. But they don't have a leak.
I don't think it's the hose that is leaking. Like you said ATF has a red pigment on it. Mine has a golden yellow pigment on it so its definitely an engine oil.I have no errors too.
I cannot find the pipe part listed online, I only found the rubber hose.
Could the clamp damage the solid pipe and crack it which might cause the leak.
