Took my 2001 225 qc into a local reputable shop near Rockford IL for new tire mounting and AWD alignment yesterday. They had quoted me $20 a tire for dismount, mount, and static balancing. They quoted me at $54.95 for AWD alignment...which is VERY reasonable. I asked them if they've done Audis before and they reassured me they've done several Audis. About 4:30 in the afternoon the shop called me and said they were unable to do the AWD alignment on my car because their manual flagged the procedure, stating they needed a special tool (which they did not have) to reset the steering sensor. They informed me that I'd have to take it to the Audi dealer for proper aligning. My dealer in Rockford is an awesome dealer, but charges $149.95 for an alignment! I then asked my shop if this special tool to reset this steering sensor was related to the ESP? He said that yes, it was. I told him no problem...mine is a very early '01 with no ESP. Unfortunately it was too late in the day to do the alignment, so I am bringing the TT back this afternoon. I guess not having ESP can also be a good thing when it comes to having alignments done. Saved myself almost $100! FYI: After doing hours and hours of researching, I purchased 4 new Wanli 225/45/17 S-1099 tires online and total cost with shipping was only $305! These tires have the same tread pattern as the Yokahamas (directional awesome V-tread), but at a fraction of the cost. I have a friend that runs these tires and he is extremely happy with their performance. I drove the TT into the Chicago area last night and then back home. I am extremely happy with their performance so far! They really grab the pavement and are very quiet. I highly recommend them. By the way, I had Michelin Pilot Sports on the TT and they were crap compared to these Wanli's.

 

So, the shop just can't turn the ESP off to align the tires? That option is available.

 

An alignment is purely mechanical.

And Wanli tires?

 

but it sounds like there is a steering sensor that needs to be adjusted on ESP-enabled cars when doing an alignment...

 

If things were way out, or a rack was replaced, but fractional angle adjustments should not affect it. This is the first this issue has surfaced, and people have been getting alignments for years!

 

but maybe most shops have the tool needed to adjust the sensor, while this one does not(meaning maybe it's not a TT-specific tool, but one that is needed on cars with ESP).

 

Wanli Truck tires??

 

Wanli manufactures a wide spectrum of tires...not just truck tires. The tires I purchased are a Z rated high performance tire and the tread is an exact replica of the Yokohama AVS Sport tire.

 

· Proceed to Section F


Section F - Front End alignment
· IMPORTANT - On quattro vehicles, prior to aligning the vehicle, torque the rear shock mount lower bolt to 110 Nm (81 ft. lbs.) with the wheels on the ground

· IMPORTANT - On front wheel drive vehicles, prior to aligning the vehicle, torque the rear shock absorber mounting lower bolt to 40Nm (30ft. lbs.) + an additional 900 with the wheels on the ground

· IMPORTANT - Subframe bolts must be torqued after doing the front end alignment

General Notes


Wheel alignment should only be checked using VW/Audi approved wheel alignment equipment

When making adjustments, keep to the specified settings as accurately as possible
Vibrations can also be caused by excessive residual imbalance and/or vertical wheel run out
Wheel alignment checks must always include both the front and the rear axles otherwise the proper running characteristics of the vehicle cannot be ensured

Test Requirements
Check suspension, steering and steering linkage for excessive play and damage
Tread depth difference of no more that 2 mm on one axle
Tires are inflated to correct pressure
Vehicle at correct curb weight 1)
1) Curb weight is defined as the weight of the vehicle ready for the road (fuel tank completely filled, spare wheel, vehicle tools and vehicle jack)

After a certain period, wheel alignment platforms and computer equipment can lose their original leveling setting and adjustments
Wheel alignment platforms and computer equipment should be serviced and calibrated at least once a year
· Precision equipment of this type should be treated with due care

If necessary, contact the manufacture for familiarization with the proper use of the equipment
Note: Setting basic settings of headlight range control or the longitudinal acceleration sensor will need to be done after doing the front end alignment


Setting Wheel Alignment


Ü Use V.A.G. Electronic Alignment machine or equivalent

Ensure that the sliding plates and turntables are not touching the end stop when checking the wheel alignment
Vehicle accurately aligned, suspension bounced and rocked several times
The test equipment must be properly adjusted and attached to the vehicle (see equipment manufacturer's instructions)
Carry out wheel run-out compensation



Note: Compensating wheel run-out: The permissible lateral run-out of the wheel rims can exceed the specified toe setting tolerance. If the compensation for wheel run-out is not performed, it will not be possible to obtain a correct toe adjustment

Ü Insert brake pedal depressor


Overview of work sequence for measuring wheel alignment
The vehicle must be at curb weight when measuring wheel alignment

Use the following work sequence

Check front axle camber and center if necessary
Check rear axle camber (not adjustable)
Check rear axle toe and adjust as required
Vehicles with front wheel drive, toe is not adjustable

quattro vehicles, adjust toe as required

4. Check front axle toe with vehicle at curb weight and adjust as required


Checking rear axle camber (vehicles with front wheel drive and quattro)

The camber can be checked but not adjusted on vehicles with front wheel drive and quattro

If the readings are outside the permitted tolerances, the axle beam must be checked for damage and possibly replaced



Centering rear axle toe (vehicles with front wheel drive)

The overall toe setting on the rear axle cannot be adjusted

By moving the rear axle it is possible to center the individual toe settings

· Loosen securing bolts on mounting brackets

· Center the individual toe settings by moving the axle beam within the elongated holes at the mounting brackets

If the overall toe setting is outside the permitted tolerance, or if it is not possible to center the individual settings, the axle beam must be checked for damage and possibly replaced

It may also be necessary to check and measure the body alignment in the area of the rear axle mounting points and repair as required


Adjusting rear wheel toe (quattro vehicles)

Ü Loosen all bolts on mounting bracket -1-

Ü Move mounting bracket -1- in the direction of arrows

· Tighten bolts to 75 Nm (55 ft lbs.)

· Always use new bolts



Centering front axle camber

The camber cannot be adjusted

By moving the subframe it is possible to center the camber within the specified tolerance range



Adjusting front wheel toe

Ü Hold tie rod end -A- and loosen lock nut -B-

Ü Adjust toe on left and right hand wheels by turning tie rod at -C-

IMPORTANT - Ensure that the rubber boots are not twisted after turning the tie rods; twisted boots wear out quickly

Ü Torque lock nut -B- to 50 Nm (37 ft. Lbs.); noting that the setting may change slightly after tightening

· If the measured toe is inside the tolerance, the adjustment is correct

· Front end alignment is complete



Ü Torque subframe bolts -11- & -12- to 100 Nm (74 ft. lbs.) and turn an additional 90O

Ü Bolts -G- have already been torqued



Ü With wheels on the ground, torque control arm bolt -16- and bolt -17- with nut -10- to 70 Nm (52 ft. lbs.) and turn 90O further

Ü Torque nuts -18- to 75 Nm (55 ft. lbs.)

· If vehicle has Xenon or high intensity discharge (HID) headlights, proceed to Section G for setting the basic settings for the automatic headlight levelers

· If vehicle is a quattro, and does not have Xenon or high intensity discharge headlights, go to Section H for setting the basic settings of the longitudinal acceleration sender (G251)

· If vehicle is not a quattro and does not have Xenon headlights the recall work is completed


Section G - Setting basic settings for vehicles with automatic headlight levelers





· The basic settings can be performed on the wheel alignment platform after front end alignment with vehicle on its wheels
