oil pressure on 1.8T

What should be oil pressure on hot idle 760rpm? engine is 1,8T AUQ

I measured 1,4Bar at hot idle, is it enough?

 

I see 2bar at around 1k@idle on a AGU.
So I guess it should be fine.

 

but flashing oil pressure I bought new oil pressure switch,new oil pump and no difference [:^(] car is golf mk2, engine AUQ

 

Oil pressure largelly depends on thicknes of the oil ie grade, age etc

1.4 Bar on idle is ok

 

but why flashing oil pressure on hot idle?

 

What oil grade have you used and how old is it ?

 

I tried firstly Mobil 1 5w50, and secondly Castrol 5w40 and no differences

from swap I drove only about 30miles, because Im afraid that destroy the engine [:^(]

 

Have you measured oil pressure during driving and increased revs?

 

cold idle about 1400rpm: 6-6,5bar
hot idle about 720-760rpm: 1,4bar
about 1000rpm: 1,8-2,0bar
about 6000-6500rpm: 6bar
about 3000-4000rpm: about 4bar

 

Nothing to worry about there bud i think

Anyone else?

 

but why flashing oil pressure?

 

Dodgy sensor?

 

today I bought new sensor

 

Yeah, I think I'm having those numbers around those RPM.

I had a sensor failing on me, and it was beeping.
Are you using the sensor for the mk2 cluster? HOw do you have this setup?

The beep/flash only comes over 2700rpm?

 

So the engine is running fine yes ? No tapping after starting ?

 

the flash comes only at hot idle (about 720-760rpm)

Im using sensor original for AUQ engine through the relay to the mk2 clusters
(but I measured groung also directly on the sensor)



what setup are you using on yours mk2 20VT?

 

engine running fine,quietly without knocking

 

Deffo electrical issue it seems, i think you can relax and drive your car normaly until you trace the fault

 

Well, IF I'm not mistaken, I used a mk2 sensor for the oil pressure as your cluster will be the one activated by it.
The ECU will not read anything from the OIL, from what I'm remember (can be wrong of course).
Have you had this working before, or it's a fresh new install?

Again, I'm not 100% sure of how it's setup on mine.

 

this working after install 20VT into my golf mk2

today Im used sensor from golf mk3 engine 1,9TD, on the sensor write 0,75-1,05bar..with this sensor is all ok without flashing, but i dont how that this sensor is for 20VT engine good
