2006 CLS 320CDI
2006 320CDI taking a lot of oil
Few months back I bought myself a 2006 320CDI 165kw (+stage1) and after I drove it a bit I did the oil change. After driving a few hundred kilometers the "low engine oil" sensor went off and sure enough, couple of hours later after checking the level manually, it was near MIN.
For testing purposes I filled the tank up to the max again and after about a 100-120km, around ~.5-1l of oil went missing. There are no leaks, on cold startup there isn't that much blue smoke (only a bit for a very short period of time) and while driving I haven't noticed any blue smoke behind me either.
What I checked/tested: external leaks, turbo, compression seems to be fine (didn't check manually, but there is no loss in power), there was no oil in the coolant reservoir, there was no oil mixed with the fuel. The oil loss to blue smoke ratio is extremely low which prompts the question "What is the cause of this oil loss?".
Does anyone have any ideas or suggestions, has this happened to anyone else before?
