As I don't know which you may have it is on the side of the head. There are two types Can on the side of the head common on GTI's and Cabriolets have 2 wires on it that are your low pressure switch and your oil pressure switch for the console gauge.
If you are running a generic or store branded Oil filter they have been know to cause issues with idle and flakey lights….
You Low pressure when running switch (that is on the oil filter flange usually white to the Cabbies), usually causes the buzzer…. The connections on the White and the single pin on the head Probably need to be tightened, cleaned, or replaced.

People that in the rest of their life are normally as honest and straightforward as the day is long suddenly, when cars become involved, turn into bent thieving lying barstewards.

ll swap out the sensor and see what happens worst case new pump so I can say I defo know its been done with my hand on heart.
If you have a Canned sensor for the Oil Pressure/ Low Oil at Idle, then you may want to check the oil pressure with a Mechanical gauge before buying the sensors.
As the worst case is that you have main and intermediate bearing issues. If you do buy a pump do the 2.0L pump as the gears are taller and have better pressure. The difference between 32 and 36mm gears.
Certain years require longer bolts to bolt the new pump to the block. I also suggest that you buy a new oil windage or sump as I have broken the fingers once that hold it on, also on the larger pumps you take the pickup tube off the old unit, and place it on the newer one as it is shorter and will clear the oil pan and allow it to mount correctly.

if the buzzer goes off under 2k rpm that is sometimes a fault in the cluster or a wiring issue. if its got MFA clocks check the earth for the cluster to the head, its a brown/white wire with ring terminal.
if the wires all look good, earth the black/blue wire that goes to the white switch on the filter housing. if buzzer still sounds its a cluster fault or wiring issue further back. if buzzer stops then its oil pressure issue

I have a 1989 Cabriolet GTi 1.8 8v DX. ~160k miles
The high pressure oil switch would light up and buzz around 2.3k rpm in 5th gear, intermittently, and go off when going below 2k rpm or over 2.5k rpm. This switch was rated at 1.53-1.93 bar.
I bought a replacement from GSF (Topran: rated at 1.6-2.0 bar white) and am getting the same issue. i have also flushed the engine with Pro-tec Engine flush, inspected oil pump, put a new sump gasket and plug/washer and fresh synta oil 10w40 incl VAG oil filter.
Still same issue!
There is no knocking noises, bangs, or hesitation or smoke.
The switch is the white one on top of oil cooler with blue/black wire. what else can i do to test?
Wiring?
Oil Pressure?

if it still comes on when wire is earthed then either the wire is damaged somewhere, the fusebox is at fault, wire from fusebox to clocks, clock plug pin is squished/dirty or cluster is faulty in some way.
there is an earth for the MFA type cluster to the side of the head so that is well worth a check, I'd have thought you'd see more cluster issues than just the oil warning buzzer but electrics can be funny sometimes
with the clocks it might be damage to the blue pcb foil, or the oil warning pcb clipped inside the speedometer. The foil isnt easy to repair but the oil warnign board can just be swapped for another

just get enough extra leads for those spad connectors on the nuts.
Go from battery to frame and frame to engine.
The other grounds you can use 14-16 ga wire and terminal connections.
www.cabby-info.com has the CIS and DIGI grounds.
