I need a bit of help ever since i bought by 2f gt late last year the oil light has been on and the buzzer has come on while driving. Ive checked the oil pressure and done an oil change everything seemed fine, but the buzzer kept going i was told if i disconnected both oil pressure senders on the engine it would stop but hasn't can anyone give some advice. 

try putting the wires to earth see if it stops

I had that with my Mk2 years ago, the buzzer just came on,  there was a dodgy connection where the wire goes onto the spade terminal. From memory this was covered with a rubber boot so you might not see kit.
