WARNING: This page is about a different car, the 2008 Volkswagen R32. However, it is still accessible from the selected car via links, so may be relevant.

Procedure

-- Install the VAG 1342 with the VAG 1342/14 to the oil filter bracket in place of the sealing plug. Refer to OIL PRESSURE SWITCH .

-- Check the oil pressure at different speeds:

1500 RPM: at least 1.7 bar
2000 RPM: 3.0 to 5.5 bar
above 2000 RPM: maximum 7.0 bar

If the specified values are not reached:

-- Examine the filter intake for contamination.

-- Examine the pressure pipe between the oil pump and cylinder block for tightness.

NOTE:

Also, mechanical damage for example, bearing damage can also be the cause of too low oil pressure.

If a malfunction is found despite insufficient oil pressure:

-- Replace the oil pump. Refer to OIL PUMP ASSEMBLY OVERVIEW .

The oil pressure must not exceed 7.0 bar.

If 7.0 bar is exceeded:

-- Check the oil passages.

Possibly the oil pressure relief valve in the oil pump is plugged.

-- Replace the oil pump. Refer to OIL PUMP ASSEMBLY OVERVIEW .
