CHECKING FLUID LEVELS

Note. ATF level is affected by ATF temperature. Checking ATF level at too low a temperature leads to overfilling. Checking ATF level at too high a temperature leads to under filling. Overfilling or under filling transaxle can lead to transaxle malfunction. ATF temperature can be read with Vehicle Diagnostic, Test and Information System or at display of VAG (1551) Scan Tool.

Note. VAS Scan Tool (5051) is required to check ATF level. Scan tool is used to measure ATF temperature. Follow aftermarket scan tool manufacturer instructions (if applicable) to check ATF temperature.

  1. Ensure transmission is not in "emergency running" mode. Park vehicle on level surface. Set selector lever to "P" position. Run engine at idle. Turn A/C and heater off. ATF temperature must not be higher than 86° F (30° C). If necessary let transmission cool down.
  2. Connect Vehicle Diagnostic, Test and Information System VAS 5051 with adapter cable VAS 5051/1, or connect VAG 1551 Scan Tool with adapter cable VAG 1551/3 to Data Link Connector (DLC) under knee bar under steering wheel according to manufacturer instructions. (Scheme 100)or (Scheme 101).
  3. Start engine. On screen 1, enter "08" for function "Reading Measuring value block and confirm input by pressing "Q" button. (Scheme 102) On screen 2, enter "004" for display group "004", and confirm input by pressing "Q" button. Read ATF temperature in display field 1 on screen 3. For moderate climates, ATF temperature must be
  4. Hang up container for ATF filling device (VAG 1924) as high as possible on vehicle. Raise and support vehicle. Place drip tray (VAG 1306) under transmission. When ATF temperature is 86° F (30° C), remove ATF plug (2). (Scheme 103) ATF level is correct when a small amount of ATF runs out while temperature is between 86° F (30° C) and 113° F (45° C). For warmer climates, ATF temperature must be between 86° F (30° C) and 122° F (50° C).
  5. If no ATF drains when at specified temperature range, insert filling hook of filling device (VAG 1924) into ATF plug hole (2). (Scheme 103) Add ATF with filling device (arrow) until ATF flows from plug opening. (Scheme 104)
  6. Always replace ATF plug gasket. Insert plug, and tighten to specification. See «TORQUE SPECIFICATIONS»(ref-169327-S27145908752004120700000). Press "arrow" button on Scan Tool (VAG 1551) Enter "06" for function "End output" and confirm entry by pressing "Q".

  1. Drive vehicle a short distance to warm up gear oil to about 140°F (60°C). Position vehicle on level surface (4-post hoist or over pit). Turn engine off and let gear oil settle to bottom of case for 2 minutes.
  2. Place drain pan under final drive. Remove fill plug (arrow) on side of final drive. see scheme 9
  3. If necessary, remove heat shield and input shaft from transmission, to gain access to bolt. Gear oil level should be at lower edge of fill hole. Add appropriate fluid as required. See «RECOMMENDED FLUIDS»(ref-169327-S10889948922004120700000). Install fill plug with NEW sealing ring. Tighten to specification. See «TORQUE SPECIFICATIONS»(ref-169327-S27145908752004120700000).

DRAINING & REFILLING

CAUTIONDO NOT start engine without ATF. Vehicle must also not be towed unless there is ATF in transmission.

ATF LINES & ATF COOLER FLUSHING

WARNINGWear appropriate protective eye wear during procedure.
CAUTIONIf there is debris in ATF, blow through ATF cooler and ATF lines with no more than 145 psi (10 bar) of compressed air before installing transaxle.

  1. Remove bolts (2, 3 and 5). see scheme 12 Remove ATF lines (6 and 7) from transmission.
  2. Attach hose to ATF line (6) and secure with hose clamp. Insert other end into suitable container. Apply air pressure several times into ATF line (7). Position hose from ATF line (6) to ATF line (7) and repeat. Tighten ATF lines to specification. see scheme 12
  3. Check ATF level and add ATF as necessary. See «CHECKING FLUID LEVELS»(ref-169327-S29876757632004120700000) under LUBRICATION.
