What is the harm of removing the pump altogether?

Great write up and the pictures really help :-)
I'm trying to get my 2.0L 2002 Beetle through CA smog.

It has no CEL issues, but it fails the readiness for SAIP with "failure or not complete".

The pump runs when the engine is cold and seems to suck air ok. The output from the SAIP goes directly to a valve on the rear of the engine (combi or EGR) but is not vacuum controlled - I'm a puzzled by this.

The hoses all seem to be in good shape.

I did find a broken vacuum hose between the manifold and fuel pressure regulator - this cleared an O2 heating readiness issue but not the SAIP.

maybe it just takes a bunch of cold starts to clear this last readiness code or maybe there's something else like the SAIP not producing enough air or the valve is stuck ?

My SAIP seems to be a one piece job.

Any ideas ?

if you want to get a nice look, use some socket head or button head cap screws adn nylock nuts....

@ Beetle1.8turbo

There are a few part numbers. Mine also needed the 3 mounts on the pump and I've found that either 078 906 601 m or 06A959253 (but NOT with a B on the end) look to be the correct one for my car which is a 2000 APH 1.8t, I think it changes to the one with the B in 2001 but most Euro parts go on actual build date of the car, the US change 'model year' in October of the year before which may catch people out.

I hope that helps someone else, I was sent the wrong one by a supplier despite checking that it was for a 2000 APH so I've spent a few hours checking. The 2 part numbers above both cross reference to the same part in Pierburg catalogue.

There is no way to fix the pumps that have no rivits. I think they must have switched to the rivetless design sometime late in 2001 since it seems none of the 2002 on up have the rivits anymore. If your pump is bad it will need to be replaced.

Seems all the new pumps or aftermarket pumps don't have rivits either.

Read my above post again. They changed the design sometime in 2001 so none of the 2002 on up Beetle's have the old rivet design pumps. Yours is a 2002 so you already have the new and improved NON-rivet design.
Only way to fix it is to replace it.

Indytom just opened my engine cover and found out that the tube lines were the air leeks was not totally place properly in the SAP and loose. When I push it in, it click and locked. Now it wont make a jet engine sound no more!! yepey..thanks org!!
