om605 vacuum hiss?
Hello,
I am still learning about the new to me om605 powered W202 C250. I'm curious what is causing a back up of vacuum pressure, that's the only way I can describe it. When I turn off the engine, it slowly releases but I can totally release it if I pull a vacuum line.
Hopefully the link to this short video of it will post here. Not 100% sure about the forum rules linking to YouTube.
I am not sure how this has, or whether it has been, affecting performance. I have blocked the EGR line with a 5.5mm metal bit but otherwise the setup is stock AFAIK.
Thanks,
Jon
