That was a piece of junk - weeks on end back at the dealer for EGR valve issues (more than once, and we weren’t the only ones complaining) and a major oil leak. 
The Sport SD4 had massive and annoying lag. You’d put your foot down to pull out into traffic and nothing would happen for a few seconds, then it would kick in violently. After 3 years, I had almost learnt to anticipate a break in traffic and start accelerating when the last car was directly in front of me, counting on the lag to not take off until it had passed. Not fun. 
The D5 is showing none of that. Quite smooth and quick off the mark.  I should add that I always drive with the gearbox in Sport mode. 
I agree with the comments above re the TD6. I test drive that and it was much nicer, smoother and with a nice low note, not the high rev of the SD4. Unfortunately it was out of the lease budget. 
Also agree re the sensor/camera/audio glitches. Sometimes the rear camera just doesn’t come on and my iPhone 6 won’t play more than 1 song when connected by cable without switching to loud static.
