Tdi intake upgrade questions

So I have a 98’ jetta that has the ahu engine and I ordered a pd130/pd150 intake manifold with the driver side inlet and an egr delete pipe, my question is should I expect any check engine lights or anything like that, also how do I go about deleting the n18 solenoid, or do I even have to
Any help would be great, thanks!

I can't tell you exactly what will happen if you unplug the N18. I do know on the 4th gen, as soon as you unplug that solenoid, you'll get a CEL. If that happens, you'd want to put a 5k resistor or so across the 2 conductors that go to the solenoid so the ECU will think that the solenoid coil is still working.

If you elect to leave it in place, you'll want to plug the end of the vacuum port so that you don't lose all your vacuum when it activates. A short piece of vacuum hose and a plug in the end of it should work.

Will you get a CEL after deleting the EGR? Again, for the AHU engine, I don't know. Good luck!

EGR is monitored, so yes if you disable it you will set a DTC.

You need to change the software, which in the case of the older cars, means replacing the PROM "chips" on the ECU board with ones that have a different program on them, as those ECUs are not reflashable.

yes. remove bulb for CEL, done lol, nah you need a tune to rid yourself of it. you need to get creative to torque the intake down. if you have issues, shoot me a pm for my backyard tested and proved method, its hagard and ghetto as all get out but works like a charm for getting the right torque down. You also should gasket match the pd150 the ports.
