Buzzing noise (Oil)

[Miacant]

Gambit, thanks.

Can see you're quiet busy threading replies this afternoon.

Hope I can get in touch with Vr6 for help.

Cheers.

Hi Miacant, there are two oil pressure switches on the engine and if either of the switches goes faulty it should operate the buzzer. If you have checked the oil pressure with a guage and it is within specs, go for the switches. One of the switches is normaly open contacts and the other is normally closed. To test these I use 2 test lamps, one end of each connected to battery positive and the other end of the test lamp to each switch, then with engine stood one lamp should be lit, and when you start the engine it should go out and the other should light. Watch for either of them flickering or not changing over. If you do replace the switches, make sure that you put the correct switch in the correct location. I have also seen some cars with the strainer on the oil pick up pipe blocked, this causes the oil pressure to drop as the engine revs are increased, drop the sump off and clean out.

hi Miacant

on the oil pump there was a very slite scoring on the face of the oil pump.Took it to work skimmed the face and havent had aproblem since.

Mk1 & stevegti, thanks for your input.
I have booked the car in for oil pressure check 2moro.
Mechanic thinks it might be low pressure or blockage in strainer, or could be the oil pump. Hope it isn't the pump.

Will keep you posted.

Cheers.

Are you near Woking? if you need a new pump then i can fit one.

If you change your oil pressure switches make sure they're genuine VW. I bought pattern parts and the oil kept blowing through the one on top of the oil cooler.

you know what?? i have the very same problem with my gti.  after about 1000 miles after an oil change my buzzer comes on as soon as the engine becomes warm (10 15 mins) its quite annoyign if i have to drive across the city. as soon as i get my oil changed the buzzer stays off.  im worried it might be the pump?  and i have to go 3 hours this weekend to another town and im worried baout maybe not getting enough pressure i hope its the switch anyone know?

Change the switches first. If the fault is still there, have the oil pressure checked.

Reason for the buzzer noise, in my case, is to do with the oil pressure which isn't right according to the mechanic. Oil pressure switch has been replaced and as result oil light and buzzing noise has stopped. I'm a happy bunny and glad it isn't the pump.

Cheers, guys.
