Just a data point, but my M25, which has 2500 hours on it and runs well, takes a lot of cranking to start, unless I use the glow plugs for at least 30 seconds. Starts right up after that.
This isn't necessary if the engine is warm, but if it' been shut down for more than an hour or so, even in the summer, I use the glow plugs. It's easier on the starter.
I think this is a normal characteristic of the engine.
Oh... and it's really hard to get a reliable compression test with one of those cheapo gauges that have a rubber tip that seals up against the injector/spark plug hole. The only way to have a reasonable shot a getting somewhat accurate readings, is with the type that has a hose that screws into the injector/spark plug hole.
