Fault in the main brake system
If the ABS warning lamp
lights up together with the brake
warning lamp
⇒
page 31, this indicates a fault in the ABS func-
tion, and possibly a malfunction in the main brake system as well
⇒
.
If there is a malfunction in the brake system the symbol
will light
up in the instrument cluster. Please refer to
⇒
page 31.
Fault on the electronic differential lock (EDL)
The EDL works in conjunction with the ABS. If a malfunction should
occur in the EDL, this is indicated by the ABS warning lamp
.
Please take the vehicle to a qualified workshop as soon as possible.
For further information on the EDL

WARNING
•
Before opening the bonnet and checking the brake fluid level,
observe the warning information on
⇒
page 221, “Working on
components in the engine compartment”.
•
If the brake warning lamp
should light up together with the
ABS warning lamp
, stop the vehicle immediately and check the
brake fluid level in the reservoir. If the fluid level has dropped
below the "MIN" mark you must not drive on - otherwise there may
be an increased accident risk. You should obtain professional
assistance.
•
If the brake fluid level is OK, the fault in the brake system may
have been caused by a failure of the ABS control function. As a
result the rear wheels can lock relatively easily when braking. This
could cause the tail of the vehicle to skid sideways. Drive carefully
to the nearest qualified workshop and have the fault rectified.
Applies to vehicles: with Audi hold assist
Audi hold assist
This warning lamp monitors the Audi hold assist function.
Audi hold assist helps the driver to keep the vehicle stationary while
the engine is running, for instance on steep gradients, at traffic
lights or in stop-and-go traffic. When the Audi hold assist function
is on, you don't have to keep your foot on the brake to prevent the
vehicle from accidentally rolling away. Once it detects that the
vehicle is stopped, Audi hold assist keeps the vehicle stationary. The
green symbol
in the instrument cluster indicates that the func-
tion is activated. You can now take your foot off the brake pedal.
When the vehicle has been stationary for an extended period, Audi
hold assist will automatically apply the parking brake. In this case,
the green symbol
will change to red
.
Electro-mechanical parking brake
This warning lamp monitors the electro-mechanical
parking brake.
The warning lamp
lights up when the parking brake is applied
with the ignition on. After the ignition has been switched off the
lamp will stay on for about 30 seconds. The warning lamp will light
up for about 30 seconds if the parking brake is applied with the igni-
tion switched off.
The warning lamp should go out when the parking brake is released.
If the warning lamp flashes continuously after the parking brake has
been applied, the brake may not be strong enough to hold the
vehicle on a slope. This may be due to the brakes overheating.
Please note the following points:
•
If the gradient is too steep to park the vehicle safely, the display
will show the message Caution: Vehicle parked too steep.
•
In the event of a fault in the parking brake system the symbol
will also appear in the instrument cluster display together with the
