Default How to fix Oillamp flashing

I have an Audi A4 avant 1998.
At first when I went in 4 or 5th grear the red oil lamp starts blinking when I was above 1500 RPM and below 1900 RPM. This is because bad oil circulation.
After changing oil the result was 1500-1700.
After using motor flush and changing the oil and filter it only flashed at 1500-1530 or so..
I also changed the oil pressure indicator but it didn't help.
I use synthetic 5W-40 oil.
The lamp dont start flashing below 1500 rpm or at low speeds and only after about 7 minutes or so from starting the motor.

Hey guys new here having troubles of my own. Mine are unlike everyone's that I have red. My 02 1.8t keeps giving me a low oil pressure warning. I changed the oil pressure switch made it worse? Checked oil pressure manually and all looks good. Fresh oil full synthetic. After knowing my pressure is good I've put about 1,000 miles on it with the pressure light still coming on and going right back off but no motor issues what so ever. Another thing is light only comes on for a half second but only between 1,500 and 2,000 rpms after get higher or lower then that goes right off. Help please!!!
