Volkswagen Tiguan Service and Repair Manual: Wheel Alignment

General Information and Special Tools

Special tools and workshop equipment required

• Wheel Alignment Computer -VAG1813- or VW/Audi approved wheel alignment devices
• Brake Pedal Actuator -VAG1869/2-.
• Insert Tool - 18mm -T10179-
• Shock Absorber Set -T10001-

Wheel alignment must only performed using VW/Audi-approved wheel alignment equipment!

Wheel alignment checks must always include both the front and rear axles.

Otherwise centering of toothed shaft cannot be guaranteed!

• Perform alignment using the alignment computer.

All information needed for the alignment can be found in the alignment computer.

Current data "updates" are stored in VWServiceNet.

Note

• Wheels should not be aligned until the vehicle has been driven 1,000 to 2,000 km (621 to 1242 miles), since it takes this long for the coil springs to settle.
• The individual specifications should be followed as exactly as possible when making adjustments.

When Vehicle Alignment is Necessary

• Vehicle shows handling problems.
• There is an accident damage and components were replaced.
• Axle components have been removed or replaced.
• Tire wear patterns are uneven.

Test Prerequisites

• Suspension, wheel bearing, steering and steering linkage checked for excessive play and damage.
• Tread depth difference may be no more than 2 mm on an axle.
• Tires inflated to the inflation pressure.
• Curb weight of vehicle.
• Fuel tank must be full.
• Spare tire and vehicle tools are installed in appropriate position in vehicle.
• The water container for the windshield/headlamp cleaning system must be full.
• Make sure the sliding plates and turntables are not touching the end stop when taking measurements.

Caution

Test equipment must be properly attached and adjusted; observe equipment manufacturer instructions!

If necessary, contact the manufacturer for instruction on the proper use of the alignment tester.

After a certain period, wheel alignment platforms and computer equipment can lose their original leveling setting and adjustments.

Wheel alignment platforms and wheel alignment analyzer/computer should be serviced and calibrated at least once a year.

• Treat these highly sensitive units carefully and conscientiously!

Measure Preparations

Special tools and workshop equipment required

• Brake Pedal Actuator -VAG1869/2-.

The lateral run-out of the wheel must be compensated for. Otherwise, measurement will result in false readings.

A correct toe-in adjustment will not be possible without performing lateral run-out compensation!

For this, observe notes by manufacturer of wheel alignment equipment.

• Perform wheel run-out compensation.
• Install the Brake Pedal Actuator -VAG1869/2-.
• Actuate the brake pedal using brake pedal actuator.

Front Axle Camber, Correcting

Special tools and workshop equipment required

• Torque Wrench 1332 40-200Nm -VAG1332-

Note

• Camber correction is required only after repair work on chassis. The camber is not adjustable, however it can be rearranged by sliding the subframe!
• Slide subframe only toward left or right, under no circumstances in or against direction of travel!

 

• Remove the noise insulation.
• Loosen bolts -1- for subframe -2- to body on both sides.

Adjusting the camber is limited by the subframe hole tolerances. If moving the subframe does not reach the specified value, then check the installation.

• Only specified value for camber can be adjusted by moving subframe -arrows 3-.
• Bolt on subframe to body with additional torque angle using new bolts.

After sliding subframe and steering gear along with it as well, clearance between universal joint of steering column and cutout of bulkhead must be checked.

• Remove securing nuts -arrows- and remove foot well trim.

There must be at least 5 mm of clearance between universal joint -2- and cutout in bulkhead.

Rear Axle Camber, Adjusting

Special tools and workshop equipment required

• Insert Tool - 18mm -T10179-
• Torque Wrench 1332 40-200Nm -VAG1332-

• Loosen nut -A- of threaded connection of upper transverse link at subframe.
• Adjust camber by turning hex of eccentric bolt -arrow-.

Note

The maximum adjustment range is 90º to left or right of center position.

• Tighten nut -A-.

• To do so, use the Insert Tool - 18mm -T10179-.

When using Insert Tool - 18mm -T10179-, tighten nut to 80 Nm.

• After tightening the nut -A-, (Fig. N44-10035.

Rear Axle Toe, Adjusting

Special tools and workshop equipment required

• Torque Wrench 1332 40-200Nm -VAG1332-

• Loosen nut -1-.
• Turn eccentric bolt -2- until the specified value has been reached.
• Now tighten nut again.

Front Axle Toe, Adjusting

Special tools and workshop equipment required

• Torque Wrench 1332 40-200Nm -VAG1332-
• Torque Wrench 1332 Insert - Open Ring Wrench - 24mm -VAG1332/11-

• Loosen lock nut -3-, counterhold at tie rod end -2- when doing so.
• Remove open spring clip -1- from boot.
• Adjust the toe by turning the left and/or right tie rod.

For this purpose, an open-end wrench can be placed on hex head of tie rod.

Be sure that boots are not twisted after turning tie rods!

Twisted boots wear out quickly.

• Tighten lock nut with Torque Wrench 1332 Insert - Open Ring Wrench - 24mm -VAG1332/11- while counterholding tie rod end -1-.
• Check toe value again.

Setting may change slightly after lock nut is tightened.

If the measured toe nevertheless lies within the tolerance, the adjustment is correct.

• Install the spring clamp on the boot.

Tightening Specifications

Component	Tightening Specification
Tie rod end to tie rod	70 Nm

Basic Setting for Steering Angle Sensor -G85-

If steering wheel is offset, Basic Setting of Steering Angle Sensor -G85- must be checked! Perform a basic setting in Guided Fault Finding using Vehicle Diagnostic Tester.

Use the GO TO in "function/component selection".
