Gavin Hamson 25 Posted December 28, 2020 Report Share Posted December 28, 2020 Hi Everyone, PO had fitted BOE CAI, however the vacuum hose arrangement doesn't look right. Car is MY12 NA. The red vacuum hose to the exhaust flap solenoid valve and the hose off the inlet manifold are not connected to anything - see pic. The vacuum switching valve is electrically connected but has no hoses connected which I think is correct. The BOE fitting instructions are not too clear on this (to me!). I think the red exhaust flap hose should connect to the inlet manifold take off? Quote Link to post Share on other sites
Solution agentdr8 150 Posted December 28, 2020 Solution Report Share Posted December 28, 2020 You would be correct. The exhaust valve is controlled by another solenoid (VSV) mounted to the rear subframe, and it needs a vacuum source. I would connect the red and black hoses together. As it stands, you currently have a vacuum leak. 1 Quote Link to post Share on other sites
