    Hi Everyone!

    So i had my car in for service, had to change brakes and some oil and got some updates aswell, however they said that the problem i was talking about ( Dump vale sound), was in fact not a problem, they thought it should sound that way since the car had high boost on the turbo and when the air is released the sound would be heard, or something like that... Seems odd, i drove one before i bought this one and i can't recall it making that sound... Damn incompentent serviceppl from Opel(I'm swedish)... I guess i have to go some where else..

    But thanks again for all the answers!

    Grr...

    It's easy to check buddy, undo the three 10mm bolts that hold the valve on be carful as there is a spring holding the diaphragm in then take out and check for splits here is mine disassembled

    It's a bit tight but can be done.
    Hope this helps👍👍

    Thank you very much! I will show this to the serviceppl as well! They seem overly confident that it is not a problem... I will ask you one last question, do you think it's harmfull for the turbo/engine to be driving with? My ''thumb is in the mittle of my hand'' so too speak hehe, so i'm not that confident in fixing this my self ^^


    Friendly Regards / Benny

    Haha I see 😂 don't think it will cause any damage but better to get checked as soon as to be on the safe side mate. This valve releases the excess pressure from the induction system when the throttle body flap closes, when you release the acceleration pedal, this if not released causes pressure on the turbo turbine and slows the spool down loosing initial boost pressure between gears (excess turbo lag) 👍
