N249 bypass
« on: 16 April 2009, 21:48 »
Anyone done this?

if so, i understand that you take the hose from the FPR off and put a new piece in. connect a t-piece to the new hose you put on and then connect the original hose to the other another part of the t-piece. then you use the Vaccuum hose from the top of the DV and connect it to the 3rd part of the DV...(if im wrong please correct me)

but what happens to the hole where the vaccuum hose originally goes to? am i missing anything out? all the guides i've seen arent very clear on the whole process

thanks.

I finished it all today mate!  I completely changed the piping to and from the N249 Valve and the N112 Valve.

The N249 is now completely removed from the vacuum system but i have left it plugged in so not to bring up a fault code.  The DV i now have running off of vacuum directly from the inlet manifold and i have removed all the excess unnecessary tubbing and reservoirs.

All you need to do this mod is a couple of metres of 3mm Vacuum tubing, 1 T piece (2 if you are running a boost guage like me) some small cable ties and some spare time!
