EPC light problem, help

[onodelta]

Hello, I have a 2011 Audi A4 2.0T 4 door sedan TFSI that has EPC light comes on every time I accelerate the car over 4000 RPM whether it is in sport mode or manual shifting and after that it will not go past 4000 RPM and will automatically shift every time it is in sport or manual and the instrument cluster displays "do not exceed max engine speed of 4,000 RPM". I did not have this problem before. It gives the code"5580-P164B Oil Pressure Switch Malfunction_" under the category "Engine Management". I have already changed the oil pressure switch two times to make sure that I didnt buy one thats not working, the replacement one is OEM. I have tried deleting the code after installation and taking it for a drive but problem is still the same. Thanks.

Any luck with this?

Just a follow up to this...there are 2 oil pressure sensors. I replaced the easily accessible one by the oil filter and still had this error. After replacing the second one by the belt tensioner I no longer have the EPC light. One sensor is brown and the other is blue.

Yes, no EPC light since changing the sensor.
