I am constantly tempted to do this. Now that I have a fmic coming my way I kind of have to delete or relocate. I would prefer to delete though as a few of the parts are failing as is.


I know pscheoverdrive's writeup for it is a little long winded (some of the steps are unnecessary) and there is some debate whether or not the resistor even works.

So, Can this be done without throwing codes in the long run? I no longer suffer from the secondary air incorrect flow cel but my car does sound like a dirtdevil upon start up.


Roll call for who has a delete on what year car and if it is working or not.

ive been running without a pump for well over a year...only because ive been too lazy to work on the reloc project.

my plan is to reloc it under the intake manifold.

if you are running without it, but still have a combi valve, make sure you disconnect the vac line to the valve.

Have you tired the resistor? What is the point of that thing if it doesn't work?

ModifiedA4

so the resistor would fake the pump being there.

But the codes we get from the ECU have nothing to do with the pump. It is feedback from the O2 sensors.

therefore I highly doubt the resistor does jack **** for us.

clear them yourself, but you won't pass emissions. Think about when your next inspection is (or if you have one) and whether you'd pay to get the codes tuned out. It shouldn't be too hard for the tuner, and therefore not too expensive.

stop back in for a while - you still up in Darien?

Arrg. Relocation it is. Now I just need a pump that doesn't sound like a tie-fighter.

I assume this cel is coming from the rear o2. Modified, have you ever tried the angled non-fouler?

I just bought a house as of this past August in Fairfield so I'm up there now. I own a garage now, which the A4 has only been in once. lol.

My rents are still in Darien, so Im around town occasionally.

Still in school?

No, it comes from the primary.
