My 2003 Audi A4 have the oil light flushing with beeps when the engine runs warm(after 5mins of running from cold).
I changed the oil(5W40) and filter to no success,so I went on to change the oil pressure switch.I also tested for oil pressure which was perfect.this red flashing symbol and beeps keeps bordering anytime I move my car, can someone help me out????? I'll really appreciate it.

Post a picture of the symbol. You should also find someone with a VAG-COM who can read the codes your car has.

What is your oil pressure readings? Oil pressure switches are ground signals. Grounding the wire for the switch at idle should either make the light come on or not come on at 2000 RPM if its a dynamic oil pressure circuit.

Ezveedub,
the pressure at cold was 50psi and went down to 37 psi after warming up.
yet to try the ground thing but i removed the connector from the switch and the light still stays on.
the symbol is a red oil sign with oil drips at the tip

Ground the wire to see if the oil warning goes out. If the warning comes up when the engine is revved up at 2000RPM or more, then the wire is looking for ground at 2000RPM. The oil pressure switch must be the correct one as well. The dynamic oil pressure switches ground when the correct oil pressure is met. If ground the wire and the warning still comes on at 2000RPM, you most likely need an instrument cluster.
