Checking / Changing transmission fluid in a 01M/101N/101V tranny and final drive on Audi, Seat, Skoda and Volkswagen Tuning Support Forum.

I had a somewhat difficult time finding the info I needed so I thought I'd pass on one of the articles I found..

LUBRICATION SERVICE INTERVALS
Check fluid level at each oil change. Change fluid every 30,000 miles under severe driving conditions. Replace filter if needed during fluid change.

CHECKING FLUID LEVEL
NOTE: VW ATF (G 052 162 A2) is light yellow color.
01M Transaxle
1) Set selector lever to Park. Start engine and allow it to idle. Raise and support vehicle. With transaxle at normal operating temperature, remove ATF level plug from oil pan. Any ATF present in overflow tube (inside plug hole) will run out.
2) If only a small amount, or no ATF flows from overflow tube, filling is required. Go to next step. If ATF continues to run out, fluid level is okay. Install ATF level plug with a NEW seal and tighten to 11 ft. lbs. (15 N.m).
3) Pry off fill plug securing cap and discard. See Fig. 1. Spring retainer type caps may be reused. Pull plug from filler pipe.
Fill with VW ATF (G 052 162 A2) using Filler (VAG 1924) until ATF runs out of level plug hole.
4) Install ATF level plug with a NEW seal and tighten to 11 ft. lbs. (15 N.m). Install filler plug with a NEW securing cap if needed. Shift through all selector lever positions once. Recheck fluid level.

01M Final Drive
Park vehicle on level surface. Remove speedometer drive. Wipe clean and reinstall. Remove speedometer drive and check oil level. Oil must be between MIN and MAX markings. If addition fluid is required, add VW ATF (G 052 162 A2).

01N Transaxle
1) Park vehicle on level surface, with transaxle at normal operating temperature. Set selector lever to Park. Apply parking brake. Allow engine to idle. Remove noise insulation tray. Connect ATF reservoir from VAG 1924 filling system to vehicle.
2) Connect Scan Tool VAG 1551. Enter 02 transmission electronics. Advance until SELECT FUNCTION XX is displayed. Turn ignition switch to RUN position. Start engine.
3) Raise and support vehicle. Place drain pan under transmission. Using scan tool, press zero and 08. RAPID DATA TRANSFER, 08-READ MEASURED VALUE BLOCK should be displayed. Confirm entry with "Q" key. Enter 0 0 5 to select display group. Confirm with "Q" key. First display indicates ATF temperature. Allow temperature to reach 95-113øF (35-45øC).
4) Remove ATF inspection plug from oil pan. A small amount of ATF should drip from inspection hole with engine running. If level is okay, install NEW seal on inspection plug and tighten to 11 ft. lbs. (15 N.m). Turn engine off.
5) If additional fluid is required, pry out plug securing cap using screwdriver. Pull plug out of pipe. Fill with VW ATF fluid only and add until fluid runs out of level hole. See Fig. 1. Install sealing plug on fill tube and install NEW lock cap. DO NOT use any lubricant additives.

01N Final Drive
Raise and support vehicle. Remove plug on side of final drive. Gear oil level should be at lower edge of hole. If addition fluid is required, add 75 W90 synthetic gear oil (G 052 145 A2). Install fill plug and tighten fill plug to 18 ft. lbs. (25 N.m).

01V Transaxle
1) Park vehicle on level surface, with transaxle at normal operating temperature. Set selector lever to Park. Apply parking brake. Allow engine to idle. Remove noise insulation tray. Connect ATF reservoir from VAG 1924 filling system to vehicle.
2) Connect Scan Tool VAG 1551. Enter 02 transmission electronics. Advance until SELECT FUNCTION XX is displayed. Turn ignition switch to RUN position. Start engine.
3) Raise and support vehicle. Place drain pan under transmission. Using scan tool, press zero and 08. RAPID DATA TRANSFER, 08-READ MEASURED VALUE BLOCK should be displayed. Confirm entry with "Q" key. Enter 0 0 4 to select display group. Confirm with "Q" key. First display indicates ATF temperature. Allow temperature to reach 95-113øF (35-45øC).
4) Remove ATF inspection plug from oil pan. A small amount of ATF should drip from inspection hole with engine running. If level is okay, install NEW seal on inspection plug and tighten to 59 ft. lbs. (80 N.m). Turn engine off.
5) If additional fluid is required, using ATF Fill System (VAG 1924), carefully insert fill hose through an opening in the deflector cap. See Fig. 2. Ensure deflector cap is not pushed out of position. Fill until ATF runs out of inspection hole. Use VW ATF fluid only. DO NOT use any lubricant additives.

01V Final Drive
Raise and support vehicle. Remove plug on side of final drive. Gear oil level should be at lower edge of hole. If addition fluid is required, add 75 W90 synthetic gear oil (G 052 145 A2). Install fill plug and tighten fill plug to 22 ft. lbs. (30 N.m).

DRAINING & REFILLING
01M & 01N Transaxle
1) Remove ATF level plug from oil pan. Remove overflow tube through plug hole. Drain ATF. Install overflow tube. Screw level plugin hand-tight.
2) Add 3.2 qts. (3.0L) ATF through filler pipe. See 01M TRANSAXLE under CHECKING FLUID LEVEL. With engine running at normal operating temperature, shift through all selector lever positions once. Check fluid level. Add if necessary. Tighten ATF level plug to 11 ft. lbs. (15 N.m).

01V Transaxle
1) Remove drain plug. Drain ATF. Install NEW seal on drain plug, install and tighten to 30 ft lbs. (40 N.m).
2) Remove ATF inspection plug. Using ATF Fill System (VAG 1924), carefully insert fill hose through an opening in the deflector cap. See Fig. 2. Ensure deflector cap is not pushed out of position. Fill until ATF runs out of inspection hole.
3) Shift selector lever into park position. Start engine. Press and hold brake pedal. Shift through all selector lever positions with vehicle stationary. Shift to park position. Check fluid level. Add as necessary.
