Secondary air pump

[Effect]

Can someone clarify yes or no does a post facelift have one of these or not ?

And if so where is it because it isnt where it would be on a pre facelift

Thanks
James

Im not sure where but i can find out... ive been told a number of times by audi it does have one.

Front of the engine isn't it? Under the inlet manifold

Myself and my mechanically minded mate took off the plastic under tray after both havning had a look at a picture of what one looks like and neither of use could see it anywhere from underneath.

Does this mean it doesnt have one or that we are both stupid/blind ?

IT still shows it in etka for the 8L in 02 so yes its on facelift cars, just check the airbox for a 1.5 inch diameter tube coming of it & if so follow this & should take you to the pump, if not then hasnt got on that engine, but does show for 1.6/1.8 engines, they were a royal pain in **** for sure if they go wrong just for the noise they make, had 2 go can you believe it.

From the front of the car it's moved right and up on facelift S3's

I've had a good look on my 2002 S3 and can't see one. Looking at the parts catalogue, a secondary pump is not listed for BAM engines. That said, it is not listed for APY or AMK (pre-facelift) S3 engines either.

My 99/00 APY had secondary air pump 100%, so I know thats not true for sure.

It shows in 02 the following codes under secondary air pump search & as already stated check for the pipe of the airbox, if not there then no pump, I always believed it was removed from the facelift S3's:

1.6 litre - AVU, BFQ
1.8 litre - AUM, AUQ, APG, ARX, ARY

Defo of the ARY, I've had to replace mine (2001 TQS)

 

[Haglos]

on the weekend i took mine off my apy engine and followed the procedure to drill out the pop rivets and replace them with bolts and its still making that horrible noise so need a new 1 but i was reading you can take them off but ill try source a secondhand 1 as they are quiet expensive

 

[NHN]

Thing is on the apy anyway the air pipe that goes to the pump splits & allows water in there well did on mine & thus the unit just fecks up big time & ridiculously noisy when running, so has to be swapped out, but make sure all piipes involved are checked for cracks/damage aswell when replacing pump as rivets dont solely remove noise they just go wrong anyway, another great design from audi.

I sourced one from a VW golf for our TQS was £20 delivered, same fittings and hose connections, slightly different design and no rivets to come loose on this one

 

[NHN]

£20 delivered, thats a deal or what cause they're few hundred from audi.

 

[Broken Byzan]

Aye, it was a bit of a punt at that price, but the car is happy with it, the MIL light has stayed away since fitting it so all good here

Forge do a blanking plate for the head so you can remove it the pump, only £18 ish

How will this cope when it comes to the MOT?

Anyone done this mod?

 

[Broken Byzan]

MOT will be no problem, its the CEL/MIL you will get for incorrect flow thats the problem
