EGR valve insufficient flow

[grahamjf]

Hi all

I took my car to audi to get a diagnostic check done came back as egr valve insufficient flow.
Bought a new siemens EGR valve and I am Still getting the same fault code
The pipe feeding the egr valve has slight oily/sooty coating on the inside which can be wiped off with your finger. No blockages in the pipe.

What else could cause this fault?

I would think it may be a sensor fault...gummed up with oil/soot?

Can you by-pass the sensor?
