How do I change the diverter valve on an 2007 Audi A4 Quattro 2.0

Hello, I'm Chris. Thanks for visiting Just Answer.


I am sorry you have had to wait so long for the first contact. Sometimes this happens when the question you ask is not detailed enough or its just hard to address online. Many have viewed your post, but have decided to pass.

I will do my best to help you. I have access to many repair sites, so at the least I can provide something to address at least part of your concern if it is not something I can address from memory and experience.

I mainly work in the last half of the day 2pm-midnight cst. , so that is when I do all of my responding.

Once you get an answer, you will be prompted to rate me. You are rating my help, not the website, or answer. If you feel the need to rate negative, please save the rating so I can try again or find someone whom may be able to help better.

Thanks for using our site, we will do all we can to earn your business, again sorry we did not get to you sooner.

X Do you still need help?

X Is there any more information you can add?

X At minimum what do you need to know if I can not address all of your concern?

Yes I still need help.... I need to know exactly where it is on the car and if it is something I can access myself. I know changing it doesn't look that difficult but I have no Idea where the valve is located.


The diagnostic code is am getting is P0299 so that's how I know it's this valve that needs changing, thanks!

On the turbo is the recirculating valve, that is what needs to be changed at the front of the engine compartment, see the diagram below.

Where is the valve located? Picture possibly? Thanks!

I provided a URL link showing the valve on the turbo, in my last post, did that one not work?


Customer: replied 4 years ago.

It's just not very clear what I am looking at...

Do you know where the turbo is and can you see it?


Customer: replied 4 years ago.

I'm trying to send a photo of my engine so you can help point it out where I should be looking but it is not allowing me to upload it?

The turbo is connected to the exhaust manifold between the engine and radiator.

where would the valve be located based on this picture:

So then I probably cannot change it out myself if it is that hard to get too...

It is tight, and a lot of disassembly is required to gain access.

Well thank you Chris for your patience and answers to these questions!

Best of luck.
