At my wits end, P2432 code

[shuzj944]

My wife has a 2010 Q5 with the 3.2L motor in it. Trying to get it ready for inspection and its throwing the P2432 secondary air injection system code on me. I've searched the depths of the internet and I can hardly find any info on how to fix it. Here's what I pulled up from the vehicle with my Vagcom. Really hoping I can get some help here, I've always been able to find what I need on Audizine for my S4 and A4!

Does anyone have a diagram or a link to where I can find the pieces of the secondary air injection system? I'm not familiar with the 3.2 motor, my expertise lies with the 2.7T and the 2.0T.

This might actually be covered under the EPA warranty depending on mileage. I had both parts fail on mine, one was covered, and one wasn't.

Try running throttle adaptation to eliminate the first code. You can run the secondary air tests also in activations to test what's working and what's not.

the solenoids are mounted by the throttle body. Repair info suggests a faulty solenoid. Sometimes they test good cold and fail open when hot.

Hi.My wife has same audi and got the code P2432. it is due for inspection in a month. could you please update if you fixed the issue and what was the problem. Thank you in advance

So to update on this I bought a new secondary air injection sensor and replaced it, which was part of the problem. I also had the flow tests run on it by my local mechanic and we determined that the SAI system was indeed clogged, which is extremely common for the 3.2 motors. Fortunately her car had 119,xxx miles and still was covered (barely) by the extended warranty Audi put out for this problem. It's good for 10 years and 120,000 miles for those who don't know. Brought it to the dealer and they pulled the motor and cleaned the whole system out. Only had to pay for two exhaust clamps and had the car back within a day and a half.
