Way to Troubleshoot the Cruise Control System in
Audi
2
The cruise control mechanism found in your Audi
is designed to help the driver in maintaining
stable cruising speed.
3
The cruise control system in an Audi is generally
working in actuator mechanism, speed sensor, and
a control module.
4
When the cruise control system of the Audi is
activated, the speed sensor will send a signal to
a control module and the vacuum powered actuator
which controls the accelerator.
5
You can deactivate the cruise control system of
your Audi by simply applying the slight pressure
on the brakes.
6
The following points help you to troubleshoot
the cruise control problems in your Audi.
7
Inspect the fuse
8
The fuse of the cruise control is generally found
in the fuse panel which is located below the
steering wheel.
9
To inspect the fuse, you need to remove the
cover of the fuse panel and locate the fuse by
using the fuse diagram. Then use a fuse puller to
pull the fuse off the panel.
10
Inspect that cruise control fuse or use a fuse
tester for determining the thin metal strip
inside the fuse. If it is broken, then install a
new fuse on that place.
11
Inspect the speed sensor
12
In the other hand, check the speed sensor wiring
for damages. So, use the floor jack to lift the
front portion of the car and then locate the
speed sensor.
13
The speed sensor of the cruise control is
generally located below the transmission and at
the back of the engine.
14
In speed sensor various wires are attached to
it. So, check the wires for any damages. Due to
the damaged speed sensor, your Audi cannot rely
on your cars speed.
15
Inspect the vacuum lines
16
The cruise control system of the Audi also have
a vacuum powered actuator which is connected to
the control module by the vacuum lines.
17
You have to check the holes in the vacuum lines
of the cruise control by starting the engine as
well as opening the car hood.
18
You will hear the sucking sound when the vacuum
lines are connected to the actuator and the
control module of your Audi is damaged.
19

Inspect the throttle linkage
20
The throttle and actuator mechanism of Audi's
cruise control system are connected together with
the metal chains known as the throttle linkage.
21
The throttle linkage of the Audi can break down
when you are driving your Audi on rough terrain.
It can disable the mechanism of the control
module.
22
By using a floor jack, you can lift the car and
check the current condition of the metal chains
which is connecting the actuator or broken the
throttle.
23

Conclusion
24
If you found that any part of your cruise control
system in the Audi have any problem, then inspect
the Audi by a professional.
25
Connect with an Audi professional who has enough
knowledge about the cruise control system and the
way to fix it.
