Hello - in my Audi A5 3.0 TDI's about it so far! After reviews on Amazon and extensive information on the homepage of Liqui I have this used oil. Since the change I have unfortunately problems Motorkontroleuchte. It appears at startup and does not go off as planned. My oil changed at an Audi workshop.
I have neither Anfahr problems or anything. Only the light no longer goes out!
According mechanic I should ca 5000-8000 to switch back oil and no longer use them.
Now I know not whether it is or accident due to the oil?
