• Electric steering column adjustment is restricted or does not work at all.
• Incorrect operation of Easy Entry is not the cause. It is unlikely that external forces have led to the loss of the
stored end positions of the adjustment movement. See TSB 2015819, 48 Easy Entry function of the power
adjustable steering column intermittently does not work, for more information.
• The seat adjustments can be used to maintain the 10-inch minimum recommended distance from the steering
wheel in case of airbag deployment.
Technical Background
The steering column may be under tension due to unfavorable tolerances of the steering column and module
cross carrier. As a result, the current draw of the regulator motors is above specification, so the electric steering
column adjustment fails.

Production Solution
Additional checks are executed in production.
Service
Check the electrically-adjustable steering column
1. Remove the steering wheel column trim and detach the right
upper bolt (Figure 1).
Figure 1. The right upper bolt .
2. Use a feeler gauge to measure the gap between the steering column and cross carrier:
• If the gap is less than 0.3 mm wide:
a. Retighten the upper bolt.
b. Perform the basic settings in the electronic central electrics module, J519 (address word 09). A reset of
the control module may be necessary.
c. If the procedure is still unsuccessful, open a TAC ticket for further instruction.
• If the gap is more than 0.3 mm wide:
a. Retighten the upper bolt.
b. Identify pins 1 and 5 (center contact of motors) on the 8-pin connector on the steering column.
c. Surround the wires from pins 1 and 5 with the current pick-up clamp.
d. Use the guided functions on the scan tool to read and document measured value blocks 2 and 3 of the
electronic central electrics module, J519.
e. Perform basic settings of the steering column in the electronic central electrics module, J519. Record
the changing current values during the length and height adjustment.
f. Loosen all mounting bolts of the steering column.
g. Repeat basic settings and measure and record the current values again.
h. Retighten the steering column bolts.
i. Repeat the measurement/recording a third time.

3. The obstruction counters in measured value blocks 2 and 3 of the electronic central electrics module, J519,
indicate tension if the counters differ greatly (e.g., the value for vertical high is five times higher than the
remaining obstruction counters).
The expected current draw in correct steering columns is about 1A for axial adjustments and about 2.8A 3.4A for vertical adjustment. Current draws above these values are an indication of a tight steering column.
• If the current draw is lower and within the specifications after the mounting bolts have been loosened, the
steering column had tension. If the current draw stays low after the reinstallation, the tension is only caused
by the installation. A modification of the steering column is not necessary.
• If the current consumption rises to its original level after the reinstallation, the tension is caused by
unfavorable tolerances of the components. The steering column must be modified as described in the
instructions that follow.
Modification of the steering column to reduce belt tension
Tip: Changing the tension of the belt drive may lead to an increased noise level during adjustments of the
steering column.
1. Loosen the belt cover of the steering column:
1. If necessary, remove the footwell and steering column
cover.
2. Move the height adjustment of the steering column to a
central position.
3. Carefully loosen the side clips without damaging the
clasps (Figure 2).
Note:
Do not disconnect the wiring harness at the side on the
cover attachment.
Figure 2. Side clips.
2. Mark the position of the gear wheels and the gear belt on
the housing (Figure 3). Use a touch-up pencil so that it is
easily noticeable.
Figure 3. Positions of the gear wheels and gear
belt to be marked.

3. Carefully loosen the gear belt from one gear wheel, using
a fine screwdriver.
Note:
Make sure that the belt does not come off the opposite
gear wheel.
Figure 4. Loosening the gear belt with a fine
screwdriver.
4. Reduce the tension (Figure 5):
1. Turn the gear wheel clockwise by hand until there is no
resistance. The gear wheel should now move very
lightly.
2. Turn the gear wheel counter-clockwise until a light
resistance (hand-tight) is felt.
3. Depending on the measured gap, use the following
gear offset:
• Gap <1mm: 1-2 teeth
• Gap <1.7mm: 3-5 teeth
Figure 5. Turning the gear wheel to reduce
tension.
5. Place the gear belt by hand on the gear wheel (Figure 6).
The identification on the belt must match the identification
on the housing.

belt, with gear offset.

7. Set the basic settings:
1. Reprogram the steering column with V.A.G. scan tool 5052 in the basic settings for electronic central
electrics module, J519.
2. Verify that the changing current values during length and height adjustment are within specification.
3. Perform a function check.
8. Reassemble the steering column.
9. Verify the proper function of the adjustment.
