|
Oil pressure tester -V.A.G 1342- |
Oil level OK: checking
→ Booklet. |
Engine oil temperature at least 80 °C (radiator fan must
have run once). |
– |
Remove oil pressure switch for reduced oil pressure -F378-
→ Chapter. |
– |
Screw oil pressure tester -V.A.G 1342- into hole for oil
pressure switch. |
– |
Screw oil pressure switch for reduced oil pressure -F378-
into hole in oil pressure tester -V.A.G 1342- to seal it. |
Check oil pressure at idling and at 2000 rpm |
Oil pressure at idling speed: at least 0.6 bar. |
Minimum oil pressure at 2,000 rpm: 1.5 bar. |
Check oil pressure at 3,800 rpm |
– |
Remove electrical connection from oil pressure control valve
-N428-
→ Anchor. |
– |
Increase engine revs to 3800 rpm and read off oil pressure
on the oil pressure tester -V.A.G 1342-. |
Minimum oil pressure at 3800 rpm: 2.8 bar. |
If specification is not attained: |
– |
Connect electrical connection to oil pressure control valve
-N428-
→ Anchor. |
– |
Interrogate the engine control unit event memory and delete
all event entries
→ Vehicle diagnostic tester. |
– |
Check valve for oil pressure control -N428- with
→ vehicle diagnostic tester. |
Note
Mechanical damage, e.g. to bearings, could also be the cause
for oil pressure being too low. |
– |
Renew oil pump
→ Chapter. |
Check oil pressure switch for reduced oil pressure -F378-
(brown): |
|
|
|
– |
Connect brown wire of tester to earth (-). |
– |
Connect voltage tester -V.A.G 1527B- to battery positive (+)
and oil pressure switch for reduced oil pressure -F378- (brown)
using cables from auxiliary test set -V.A.G 1594C-. |
– |
If LED lights up, renew oil pressure switch for reduced oil
pressure -F378-. |
If LED does not light up: |
– |
Start engine: At 0.3…0.6 bar the LED must light up,
otherwise renew oil pressure switch. |
Check oil pressure switch -F1- (blue): |
– |
Connect voltage tester -V.A.G 1527B- to battery positive (+)
and oil pressure switch -F1- (blue) using cables from auxiliary
test set -V.A.G 1594C-. |
– |
If LED lights up, renew oil pressure switch oil pressure
switch -F1-. |
If LED does not light up: |
– |
Remove electrical connection from oil pressure control valve
-N428-
→ Anchor. |
– |
Start engine and increase rpm: At pressure of 2.15…2.95 bar
LED must light up, otherwise renew oil pressure switch. |
– |
Connect electrical connection to oil pressure control valve
-N428-
→ Anchor. |
– |
Install oil pressure switch for reduced oil pressure -F378-
→ Chapter. |
– |
