Fluitend geluid

Berichtdoor Wouter » 29 jan 2010, 16:22

Al een paar keer geconstateerd dat wanneer ik de Benz op slot doe (centrale vergrendeling) na een paar seconden een fluitend geluid hoor. Het lijkt erop dat er een "lek" zit in het vacuum, maar alles gaat wel op slot. Iemand enig idee of dit leidt tot een compleet defect of niet?

Groet Wouter

Wouter, het sissende/fluitende geluid komt uit je bestuurdersdeur, en wordt veroorzaakt omdat het 'open' systeem belucht wordt (=lucht aanzuigt) zodat het 'sluit' systeem (dat op dat moment wordt aangesloten op de onderdruk alle sloten kan sluiten.

Op verschillende plekken op de site wordt uitgelegd hoe het systeem werkt, compleet met schema's en foto's.

Hoi Wouter, ik ken de 'layout' van het gehele vacuum systeem niet, maar er zullen vermoedelijk wel wat terugslagklepjes in zitten. Dat fluitende geluid wil dus zeggen dat er lucht wordt aangezogen op het moment dat je de deur op slot draait en middels onderdruk/vacuum de sloten 'op slot' worden 'gezogen'.
Ik zou zeggen, luister goed waar het fluittoontje zich voordoet (bij welke deur / achterklep / tankdop / "eierdoos" onder de hoedenplank (gebobbelde plastic bak rechtsachter onder de hoedenplank wat als 'vacuum-voorraadtankje' dient). Kijk ook eens de makkelijke aansluitingen na (rubber koppelstukjes bij de motor-stop-schakelaar en evt. koplampen (indien je hoogteverstelling hebt).
Bij een goed werkend vacuum systeem moet je toch zeker een keer of 5 de deuren op en van het slot kunnen doen zonder tussendoor de motor te moeten starten om weer vacuum op te wekken.

Even simpel (denk ik): op slot doen is vacuum aan de op slot kant en beluchten van de nietopslotkant.
