Mine on occasions does a heavier than i'd like it clunk, but its being doing it for a few years. what not post a video of it so it can be assessed more accurately?

Mine lands with a bit of a thump too. Having only owned manual roof convertibles (Mazda MX5) before, it was a surprise to me but I'm sure it's normal.

Mine also bangs down onto the screen top, probably due to the weight of the roof header overcentering. I just catch it with my hand to stop the bang.

Take a couple of hours to lubricate every pivot/joint/hinge in the entire roof mechanism.
Do it first with a PTFE spray (B&Q) and a week later with a white lithium spray grease (again B&Q).
This reduces the friction load in the mechanism hence operating pressures/heat in the pump decrease. Roof operating process becomes smoother/quieter and faster..

My roof always pauses for a fraction of a second before it shuts, but my colleagues car, which she always had problems with the roof, would crash down. Hydraulic cylinders can be designed so that they cushion on the last part of the stroke, don't know if that is so with these, but the roof cylinders on my car exhibit such an action.
Or my roof hydraulics could be down on pressure so it falling under gravity and last moment pressure builds to shut.

Mine used to do this.

Lubrication caused a very jerky mechanism so I can’t recommend that.

There are two sets of rubber stops for the rear clamshell which can be adjusted up to help stop the slam.

Yours may have moved down as the design is poor.

Find them, put some sticky felt on them, sticky side against the rubber stop and this should help soften the impact.

It’s been like that for years on mine (extra felt on the rubber stops) and is fine.

Just lift up the cover you will see the pump has a clear reservoir. It would appear that about half full is the norm, unless someone else can advise otherwise.
