Interesting on my 112, the owners manual goes into great detail on how to drain and refill the cooling system but my D4 manual says hardly anything about it. Both are D315 engines just a year apart. My rule of thumb is that if you cannot get as much back in as you drained out, there is an airlock somewhere.
