Not sure if anyone else has experienced a similar problem?
If it's coming out of the top of the cap, its maybe slightly over filled. And no, there is no sure fire way to know when it's correctly filled, other than it doesn't come out of the cap.
The little sight glass and plunger affair onto, is not really accurate at all.
So it's best guess, followed by mop up with rag/ top up bit by bit.
As long as it's not leaking anywhere else, then you are good to go.
Where did you buy the pressure switches? SNGB?
Funnily enough I did wonder if it was becasue I was over filling it. My only reservation with that is that quite a lot leaked out and surely I couldn't be overfilling it that much . And it was coming out beneath the black cap not the little viewing window. Reading through a few old threads too I read that the sls stops working if the pressure is below a certain amount so I assumed that I was losing pressure in the reservoir? I've only ever noticed the suspension rise up once and go back down so it's possible that it's just not working at all. All fun and games. I've never driven another 40 so don't really have anything to compare the brakes to either.
I had originally got a pressure switch from SNGB but it didn't solve my problem so ended up taking it to a Jaguar specialist near me who managed to get some NOS switches for a very reasonable price. No idea where he got them from and he didn't seem to be able to get anymore unfortunately. He also had a very cool looking 40 track car for the historic racing series so is clearly a bit of a fan
