K03 or k04?

[Max Read]

Just a quick one, how do you know if you have a k03 or k04 turbo?

What are the signs?

Cheers!

If you've got an S3 it's a k04. If you have an A3 it's a k03 unless it's been converted to a k04.
Other than that you would have to look at the part number on the label on the turbo itself

If you gave a K04 turbo the diverter valve will be at the front of the engine.
If it had a K03 the diverter valve will be on the turbo.
In this photo the car has a K04 turbo and you can see the diverter valve between the front corner
of the engine cover and the rubber seal of the black slam panel.
