249N bypass question.

[a4_1.8t_01]

I hear some guys bypass it. What are the advantages? And how would you do it? Thanks.

T the vacuum line from the front of the intake manifold. When you T it, one line goes to the DV and one to the N249. It tricks the N249 into thinking its still working, but the DV actually is running directly off the manifold. I noticed a little bit better response from my DV when I did it to mine.

My DV is already running from the front of the manifold. Doesnt the N249 already have a line going to it? I dont know which one it is lol.

Well that is the line that is supposed to go to it. Perhaps someone T'd it off something else. As far as I know you can't remove these without a CEL. Only Bypass. Lots of info on this over on VWvortex in the 1.8t section. MkIV guys do it mucho.

Alright thanks. I think mine is already bypassed but nothing is td off lol.

its way easy to "remove." just plug your dv straight into the manifold then unplug the n249 and rig in a resistor. it tricks the ecu. i have been running mine like this for about a year with no issues.
