I have seen a lot of time the advice of letting the oil drain overnight so the sludge comes out.However,I was told that the E430 does not have a drain plug and the only way of changing the oil is from the top.If this is right, how much sludge will the machine take out?Also, it would seem even more appropriate to change it often and not wait for the FSS.As always, thanks !!

Or though they are to phase out drain plugs, I believe yours still has one.
It can be drained via plug or suction, however more oil is removed via suction than draining.
Also keep in mind the Flexible service system on your vehicle. Via a sensor in the oil pan the system can tell when oil change is due, basically dont worry about it. As for sludge, you should not have any on a car as new as yours.
