Made a huge mess in the process... I'm guessing 50ml of diesel means somewhat tired injection pump. I know that that "Oel" cap has not been removed for near two years, so hopefully that 50ml stretched out over two years isn't a sign of impending injection pump rebuild?
Speaking from my limited experience, probably not. That doesn't seem like a huge amount to me. If a little diesel in your IP is the only issue that you're having, consider yourself blessed

Rebuilding the IP isn't something that folks ordinarily do. The only reason that I rebuilt mine was because of a small vacuum leak in the governor. While I had it out for that, I thought it prudent to take it to a Bosch shop and have them give it a once over if, for no other reason, preventative maintenance. ~$800.

My car now starts easier, smokes less, and is much smoother at idle. I haven't yet been able to test for better fuel economy, but hope to when we get nicer weather.
