Thanks guys. I'll check out the bleeder valve-is there definitely one on a W124?
Understood on the filter-just picked up 3 of them. Changed the Diesel filter today, as I have an incomplete service history on that car and figured that would be a good first step. Next I'll flush it and replace the filter again-should be good for a long time after that.
