Oil Pump
Special Tools And Workshop Equipment Required
- Torque Wrench (5-50 Nm) V.A.G 1331
- Oil Collecting and Extracting Device V.A.G 1782
The transmission oil pump can be replaced without removing the transmission. The vehicle must be raised and any covers installed on the bottom of the front end must be removed. The control arm to strut connection does not need to be separated. The drive axle also does not have to be removed. You do not need to perform a basic calibration. Only the DSG transmission fluid and pump cover have to be replaced.
Removing
-- Remove the noise insulation. Refer to Description and Operation .
-- Remove the lower section of the left wheel housing liner. Refer to Removal and Installation .
-- Place the oil collecting and extracting device V.A.G 1782 under the transmission.
In regard to contaminated fluid, also observe information on changing the filter. Refer to DSG TRANSMISSION FLUID => When To Change the Oil Filter .
-- Remove the plug -A- near the pendulum support.
Up to transmission production date "September 20, 2004", transmissions with two plugs were installed.
A plastic overflow tube is located in this hole (with a 8 mm hex socket head, tightening specification: 3 Nm). Its length determines the fluid level in the transmission.
-- Remove the overflow tube.
-- Drain the transmission fluid.
-- Tighten the overflow tube to 3 Nm.
-- Replace the seal -arrow- on the plug.
-- The oil collecting and extracting device V.A.G 1782 remains under the transmission.
-- Remove the bolts -arrows- and remove the cover -A-.
There is still fluid in oil pump cover.
-- Remove the bolts -arrows- and the oil pump -1- from the alignment pins and pull the input shaft from the pump.
Remove the top bolt using the special wrench, long reach T10054.
Installing
-- Insert the oil pump input shaft -A- all the way into the transmission. Turn the input shaft while doing this.
-- Always use a new metal seal -B-.
- The 2 alignment pins -C- must be inside the transmission housing.
-- When positioning the oil pump, pay attention to the input shaft splines and correct seating on the alignment pins.
Various oil pump bolts -1-
All four bolts -arrows- with flat heads
Tightening specification:
- 5 Nm + 90° (1/4) additional turn
3 bolts with flat heads, and top bolt -arrow- is countersunk
Tightening specification:
- Countersunk bolt: 8 Nm without a tightening angle (tighten using the special wrench, long reachT10054)
- Flat head bolts: 8 Nm + 90° (1/4) additional turn
-- Set the new oil pump cover -A- in place and tighten the new bolts -arrows- in a diagonal sequence and in several steps to 8 Nm.
The transmission does not have any fluid. You must now add new DSG transmission fluid and adjust to the correct oil level. Refer to TRANSMISSION FLUID LEVEL, CHECKING AND ADDING .
-- Install the left wheel housing liner. Refer to Removal and Installation .
-- Install the noise insulation. Refer to Description and Operation .
