Technical Oil light help

[nickphonics18]

i have a MK2 1.2 16v sporting. i had a service done about 3-4wks ago. the oil level is on the max still but my red oil can symbol has come on today.... what could this mean? as the oil level is perfect .....

low oil pressure if this is the main oil light?
does you car have an oil level sensor?if so that sensor could be faulty or just had a cable come loose

 

[nickphonics18]

oil pressure oh right..... the symbol is on the dash its red its a oil can with a drip coming out. so how do i sort out the oil pressure?
weird thing is this time last year after my service it did the same i thought was the oil level so i put some in....as it didnt need it i had to much so i drained some out and the light turned off.....until now.... must be dodgy censor

its a pressure sensor. what grade oil was used in there? it could be the pressure relief valve on the pump is stuck.

well its whatever oil the garage put in on the service. which im guessing is right one for punto .... isnt it something like 10w something?

so how do you fix oil pressure?

 

[custard]

well you need to find the cause.if its low pressure then the pump or relief valve as arc stated are prime suspects

and where the hell are they? haha...... take its a garage job! haha

 

[custard]

depends on your knowledge but i would be thinking back to the garage that did the oil change.

i still not had any luck...... the oil level is fine and took it to garage yesterday and they have put a new oil sensor switch on and it hasnt sorted it!!!

any more ideas??? the annoying thing is im thinking of selling it very soon! cant sell it with oil light on!!!

 

[custard]

oil sensor could be working fine.could be the actual oli pressure thats at fault

 

[nickphonics18]

so how do i fix the pressure?

ill be selling the punto very soon. got new car today

take the oil pump out, inspect it for wear. check the operation of the oil pressure relief valve.
