Another N249 Thread

[tripdiesel]

Ive been reading the post on the N249 Bypass but as alot of people seem to be im confused as there have been loads of different pictures of different bays and pipes.

Mine is a BAM LCR so where and what should i remove and run new pipe from where to where, i have 2m of red 4mm hosing sat here and i'd like to do the bypass, is there any other bypass's that can be done? as i would love to clean the bay up and springle new hoses around.

Thanks in advance

This is as simple as I can make it.

1) Disconnect the vac hoses where the red arrows are pointing to.
2) Run a new silicon vac hose between these two points (Dump valve and inlet manifold)

And what do you do with the disconnected hoses from part 1)?

 

[skahigh]

Absolutely nothing, the N249 system is completely disconnected from the rest of the system at this point.

so nothing needs blanking, is it completely reduntant at this point

Correct.

 

[skahigh]

In fact, in my fiddling today I actually removed all the crap that sits on top of the coil packs, have left the n249 unplugged for now until I get a resistor and a plug to connect in.

right, going to try find some hose then 2moz, maybe an excuse to drive up demon tweeks. Saw some in halfords £16, saw some on the Awesome site .......£3

I thought about completely removing the N249 hose circuit but by doing so, on the LC at least, you also disconnect vacuum from the N112. Are there implications to this if its done without blanking the SAI inlet?

 

[tripdiesel]

Ok now i understand that, is the hose on the inlet manifold easy to get to as it appears to be on the underside of the manifold?

Hi Fella

I tried this mod today and changed it back as the car did not boost as quick and it felt slower, so was not convinced by this at all.

I am running a Forge Motorsport cold side relocation kit and a Turbosmart Kompact Dual Port Bov that sounds absolutely mental. When the bypass of the N249 was done this morning it did not pull as hard with this set-up so changed back.

Just my experience today, it may work with my dv on full recirc.

Still worth a go.

So what are the other hoses doing then if the n249 is redundant, can it be removed to make things look tidy? if so lets see a nice diagram of what can and cant go please?

If you take a look at this vac diagram for the LCR you will see that the N249 is completely separate from everything else. I don't actually know what the N112 looks like.

Ill give it a go, i think ill just t-piece the current hoses into each other then if it feels better re-run with red hose.

Spend a little time comparing the vac diagram above with your LCR and you'll get it.

 

[skahigh]

It's not the easiest to get at but that mainly because of those irritating one use clips that I have spent most of the day removing!

Ok mate, thanks for the diagram. The LC system is quite a bit different from this. Thanks for clearing that up.

Yes those clips are a pain to remove, I used long nose pliers to pull the clip together then got a flat blade screwdriver underneath then used another pair of pliers to pull apart.....you need 3 hands.....lol......they do come off after a few choice words....

 

[skahigh]

I have spent 9 hours under my bonnet today, I'd say 4 or 5 of those were spent removing one use clips and I am NOT exaggerating!
