X1) The vehicle can be equipped either with or without ASR. The ABS/EDL lamp remains constantly lit
after ignition is switched on and the the red "brake system malfunction" symbol also lights up 3
seconds after ignition is switched on.
WARNING!
Driving the vehicle presents the risk of accident! The brake system will only be partially
functional. Because brake pressure at the rear wheels is no longer regulated vie Electronic
Brake Distribution (EBD), the rear wheels tend to brake excessively. This causes the rear of
the vehicle to break loose.
The possible causes are as follows:
Voltage supply between 6.5 and 10.5 volts and vehicle speed is above 6 km/h; carry out
"Electrical test", test step 23 page 01
-68
. Once the voltage supply is adjusted to above 10.5
volts, warning lamps will switch off again.
There is a malfunction that affects the ABS system. Check DTC memory page 01
-97
.
The VAG1551 Scan Tool (ST) is connected and the data link to the ABS control module
(w/EDL) -J104- was established. For vehicles with automatic transmission and high-line
instrument cluster, the red "brake system malfunction" symbol does not appear immediately
after the ignition is switched on. Instead, the note "Depress brake pedal before engaging gear"
appears in the display. Press the brake pedal and select a gear. The red brake warning light
appears, if the light control is working properly.
