Ok all I just received both error codes, on my 2011 Q5 TFSI 2.0T, and took it down to my local shop Autobahn Premier Service in Denver, CO.

this is what was completed:
1. My oil was dirty, so it was changed.
2. The crank case breather (06H.103.495AC) was cracked. Replaced
3. Timing cover (064.103.269H) was cracked and leaking. Replaced.
3. Both oil pressure sensores replaced (038.919.081K, 04E.919.081A)

So my issue is gone for now. I was told my particular engine did have issues with the piston rings wearing. If so Audi was replacing those engines below 100K miles.

Hope this helps.

 

Mine ended up being just a rubber gasket that wasn't put back when I got my oil changed (oil filter).. it was pretty stupid.

 

Hi

Please assist me , I have the same problem on mine and Changed the Oil pressure switches, Oil level Sensor and took of the sump and cleaned the pick up. I changed the Oil and Oil filter with OEM Parts. Also replaced crankcase breather valve. Did you get yours sorted and how
