here is the n249 delete, compliments of walkytalky on audizine. awesome guide to simplifying the vacuum lines. since you seem like the kind of guy who would be interested in deleteing everything, here is the lnk *DIY* - B5 1.8T Vacuum/Check Valve/SAI/PCV - Delete & Simplification

N249 Delete

Application Notes:
Only 2000+ has the N249 valve.

A little discussion:
On 2000+ 1.8T's,the diverter valve is not directly connected to the intake manifold like it was on the earlier 1.8T's. It is connected through a solenoid called the N249, which is able to connect it to the manifold (in it's passive state), or connect it to a constant vacuum source (in it's active state). Thus, the ECU is able to open the DV in situations where it would otherwise be closed. It is somewhat controversial to modify this system as solenoid control of the DV does have its advantages. It is able to help with pre-spooling the turbo (opening the DV at part throttle when boost request is low), and opening the DV sooner upon throttle lift. Many owners who have "deleted" the n249 have noted more "crisp" boost and more predictable DV response. In any case, the 97-99 cars did just fine without it, so we can delete it too. Here is the factory vacuum system:



What we are looking at:
RED is the vac line from DV to N249, GREEN is from manifold to N249, PINK is the path to constant vacuum source to N249.

What you have to do:
You will be connecting the DV directly to the manifold. Again, you will be leaving the solenoid itself in place and plugged in electrically while removing all the vacuum lines from it. If doing only this delete, you will simply "loop" the valve, as shown by the GREEN line below - leaving the PINK vac source in place. This delete causes no codes at all, so long as the n249 stays plugged in. Again, a suitable resistor could be put in its place.
