    There are two different versions - you could probably block it off, or buy the correct one. They're not expensive.

    "New boot is for a late 325i, where the complicated plumbing for the brake servo was simplified back to a single connection to the throttle body, a simple non return vacuum valve fitted, and the servo turned upside down to shorten the pipe run, similar to what is fitted to M40 engined E30s and all later BMW petrol models."

    Thanks for that.
    I just blocked it off .
    Yeah only paid €51 from Bolands Waterford for it.
    My brake servo just has a small vacuum pipe from it.
