The sealant bead must not be thicker, otherwise excess sealing

compound will enter the oil sump and may block the oil suction

line strainer.

– Fit upper part of sump immediately and lightly tighten all sump

bolts „diagonally“.

– Then „diagonally“ tighten sump bolts -1- to 15 Nm and bolts

-2- to 22 Nm.

Now apply an approx. 1.5 mm bead of sealing compound

-arrow- onto the clean sealing flange of the lower part of the oil

sump as shown on illustration.
– Fit lower part of sump immediately and lightly tighten all sump

bolts „diagonally“.

– Then „diagonally“ tighten oil sump bolts to 10 Nm.
– Insert dipstick guide tube.

Checking oil pressure and oil pressure switch

Special tools and workshop

equipment required
♦ Oil pressure tester -V.A.G

1342-

♦ Adapter -V.A.G 1342/14-
♦ Voltage tester -V.A.G

1527B-

♦ Auxiliary measuring set -

V.A.G 1594C-

Test prerequisites
• Engine oil level OK.
• Oil pressure warning lamp -K3- must light up for approx. 3

seconds when ignition is switched on

• Engine oil temperature at least 80 °C (radiator fan must have

run once)

Checking oil pressure
– Check oil pressure at different revolutions: 2000 rpm: 3.0…5.5

bar, above 2000 rpm: maximal 7.0 bar.

If the specifications are not obtained
– Rectify mechanical damage, e.g. bearing damage.
At higher engine speeds, the oil pressure must not exceed 7.0

bar.
If the specification is exceeded:
– Renew oil pump, if necessary

 .

Note

Observe installation position of adapter: the conical connecting

piece of adapter must be screwed into pressure hose of tester.

– Connect brown wire of tester to earth (-).
– Connect voltage tester -V.A.G 1527B- using test cables from

-V.A.G 1594 C- to battery positive (+) and oil pressure switch.

LED must not light up.

If the LED lights up:
– Renew oil pressure switch -F1- .
If LED does not light up:
– Start engine and run at idling speed. At 1.2…1.6 bar the LED

must light up, otherwise renew oil pressure switch -F1- .
