No probs.  Good luck!

is there a relay that controls the pressure switches, just had a look at all my relays and consulted the haynes manual.... my fuse board dont look like the diagram 

anyways, decided i'd check if it was the relay, unplugged both pressure switches and drove home from work, with the buzzer and light coming on after perhaps 5 mins and staying on, is this normal, or does it suggest a faulty relay?

just got a speeding fine too god damn police, why cant they catch real criminals!!!

anyhoo,

thanks rob

If you unplug the switches then the buzzer will come on when the engine is running.  Other potential is that the cicuit on the back of your speedo has been damaged.  Has it been taken out recently?

not that im aware of, think its never been toched tbh... only other things other than the pump, which i've been assured by both the geezer i bought it from and the garage i use, wont be broken, is that the 2ltre b/e needs more oil in than what the dip stick shows...

If that is the case I think that with a couple of new sensors and a bloody good flush and refill you should sort the problem.

Happy motoring!

righty, dropped the sump, the pick-up was sparkling clean, not a spec of sh*t anywhere, hardly any deposits, and i was very chuffed with it all in all, didnt have time to change the pump, so put the sump back on and changed the oil filter, both sensors and started her up... all seemed ok.

then bout 2 metres from my house, i put her in idle and the oil light started 'flickering', but not flashing intermitently, like it should...
so i topped oil up cos of filter and thought no more. revved her a couple o times, then held her arund 3,500rpm and buzzzzzzzzzzz...and it wouldnt go off, so turned her off and cursed her. walked away sneezing and genrally feeling poo.

could i have done a very stupid thing and not changed the oil-pump, which i should have, or does the idle flickering suggest a buggred relay or circuit board?

If there was no crap in the pick up I would suspect it is not that.  Getting towards the end of my knowledge on this, but electrics sound like the most likely area, but if speedo has not been out lately and the problem has not been going on that long then you should be OK in that area.

Drop a thread into the "Garage" board and see what comes back....

Sorry I can't really help any more!  Mine was sorted by this stage (not that that is any comfort to you!).

thanks for your help, very much apreciated

i'll drop a thread into the garage bit and see...

cheers,

You are doing all the trouble shooting wrong.
I had this problem and it would have saved me a lot of money if i had done 1 simple thing. and that is to get an oil pressure check carried out to see if the car is making enough pressure. the buzzer and light come on because the oil pressure is dropping below a certain figure. i think mine was something like 1.2bar. this was the pump so that was replaced.
but if your pressure is ok then it can be the wire that runs from the pressure switch to the dash buzzer.
in come case the buzzer can be the problem.
try this and see what happens.
