Bringing Vehicle Into Initial Position For Alignment (Suspension Variations 1BA, 1BC, 1BE, 1BG, 1BH, 1BP, 1BT and 1BJ)

WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2005 Audi allroad, 2004 Audi allroad, 2004 Audi A6, 2003 Audi allroad, and 2003 Audi S6. However, it is still accessible from the selected car via links, so may be relevant.

Due to the different alignment platforms, it may be necessary to raise vehicle at front axle so that it is possible to insert Spacer (VAG1925). After vehicle is lowered, it should be bottomed out. To place vehicle in initial position for alignment perform following:

Install Spacer (VAG1925) with the adapters (VAG1925/3 or VAG1925/4). See SPECIAL TOOLS .
Unscrew both thread spindles until they just come to rest against front bolts of carrier. See Fig 1 . This MUST NOT raise vehicle. Vehicle must be standing on its wheels. Vehicle is now in initial position. On vehicles with a level control system, turn ignition on and wait until vehicle height has settled. If vehicle is equipped with sport suspension (1BE), go to next step. If not, go to step 4 .
For vehicles with sport suspension (1BE), lift front of vehicle at front lifting point. Place Adapter (VAG 1925/6) on Spacer Adapter (VAG 1925/3 or 1925/4). See Fig 3 .Lower vehicle onto adapter. Vehicle is now in initial position. Go to next step.
On all except sport suspensions, this is the position in which alignment program checks whether existing toe-in per wheel corresponds to specified value of +10' +/-30' (rough pre-adjustment). If toe is not as specified, adjust toe-in to specification. See TOE ADJUSTMENT (FRONT) .

NOTE: When raising vehicle, ensure that wheels do not lose contact with turntables. If wheels lose contact measurements will be incorrect.

Place lifting jacks under front end jacking points and lift vehicle 2.4" (60 mm). With vehicle lifted as specified, push cylinder from threaded spindles and fix with safety bolts. See Fig 2 . Ensure that safety bolts are correctly positioned. Lower vehicle onto distance caliper. Observe and compare toe-in constant "S" measurement on alignment computer to specifications. See WHEEL ALIGNMENT SPECIFICATIONS .
If toe-in constant "S" measurement is as specified, check toe-in. See TOE ADJUSTMENT (FRONT) . If toe-in constant "S" measurement is not as specified, adjust as necessary. See ADJUSTING TOE-IN CURVE (ALL MODELS) .
