Hi,

My MGF has started to lose pressure and sag on its drivers side.
I have pumped to up to spec several times but after a few days it drops.
I have checked for leaks and try as I might , I cannot find any. I have checked all unions for tightness also the schrader.
Odd thing is , it seems more affected by time than use , as I recently completed a 300+ mile drive without much of a drop.
I have pumped it up around 5 times so far so I expect that if the suspension unit diaphragms are damaged the upper chamber would now have been well filled.
I'd really appreciate any useful info on this.

Kindest regards.
