AUM 1.8T dodgy oil pressure/pump ???

Hey guys! Had a quick look on the search but couldt find anything so i need some help or advice please???

I was driving home the other day when a warning light started to flash on my dashboard. it was the oil can light flashing and beeping like crazy! So i pulled over, had a look under the bonnet, checked the dipstick (plenty of oil) checked the coolant level and everything looked a-ok...

so jamp back in the car and drove a few miles home, light wentoff as soon as i set off again). But after a few miles a weird noise started coming from the engine... oil light stayed off, temp guage was fine, weird! by the time id got home (3-4 miles later) , the noise was quite noticable and thought that was it, the engine is ******! But after 10 mins i started her up again and she sounded fine, no rattling or anything!
I was away all wekend so i just took her for a 10 mile drive to see if these "problems" would happen again, but nothing?!?!

My guess is the oil pump being faulty??? or some sensor maybe?? i havent a clue??? Scared to take it for a long drive just incase the engine blows or something?!?! lol

All this happened on my audi a3 1.8t aum btw

Thanks for that!! I stupiddly drove tha car today thinking it was just a one off!!! doh!! so i wont be using her until i get the sump and pick up sorted!!! just hope i havent ****** up the turbo or anything now....

will keep ya posted!!
