I used 4mm silicone vacuum which is the right size and can be had for £2 per metre delivered from ebay. You can put resistors in the connecters but I just left the actual valves on there and still connected to the plugs so no need for resistors.
wondering if anyone can help me. ive followed this guide to do my n249 bypass and its worked great. but in the first pic where bav has circled the 2 metal pipes there is a third one to the left of them in the pic. now on my car there is nothing attached to that?? is this a problem and if so where should that rubber pipe connected to the end of it run to?? any help appreciated.
i have the aum engine and going to attempt this later...
just to clarify that the hose to use is 4mm? im wanting to remove the n249 and n112 altogether as the valve is already throwing up error codes. Where do i get the resistors, where do they fit and what do they look like?
is there a guide to remove the n112? im new to all this and new to 20vt ownership so i dont know my way around the engine yet
ive done this N249 bypass, plugged all electrical connections back in and my engine management light has came on the following morning? ive checked all vac pipes conections are tight and fully pushed in, any ideas?
Could it be that because the vacuum reservoir has been removed, there isn't enough of an immediate burst of vacuum to open the DV cleanly? And so its just sort of bleeding it off bit by bit, rather than opening nice and cleanly. If this is the case, and you have an uprated DV, fitting a less stiff spring to it should sort the problem.
