3200: constant beep from dash when under acceleration

[beau]

all fixed now, turns out the kaiser valve ( 3 way thing) was broken, so easy fix

Well done Beau, took a bit of time, but now resolved and no massive bill from a dealer to fix it....result..!!
Our 3200 does bleep several times on switch on, whilst the systems check is being done, that's normal, then it stops. You do get a long bleep if the temperature drops. I think it is used as an audible warning if any of the system fault lights come on also.

but I am wondering what can get wrong with the Kaiser (name of the Company who made it) valve ? to my understanding this is working according Venturi (name of the inventor) principles, so complete passively...so gets some dirt, oil inside..?
or am I completely wrong with my assumption ?

In my case it was the kayser valve housing, made from plastic, that deteriorated over time. The housing is supposed to hold a couple of membranes in place and as soon as the fit is no longer appropriate, that's when the issues start.
