"SCR system malfunction" flashes
Fault: Fluid AdBlue level drop below 10 liters
Remedy: Add the AdBlue fluid level to tank during the
next Diesel refuelling
13. Diagnostic test
Fault: The indicator lights
"engine - stop"
"engine - warning"
are ON
the fault code.
The fault code blinking repeats
itself continuously. It is neces-
sary to put down the fault code
number. To detect other faults, it
is necessary to push the cruise
control switch (item 3) marked
"+"
and the procedure of fault
code blinking will begin to repeat
itself - either the same fault code
appears (if there is no other fault
code) or another fault code dis-
plays (put it down) and by repeat-
ed pushing the cruise control
switch
"+"
further blinking of the
fault code will be activated - go on
in that way until the first fault code
appears again.
On termination of the diagnostic
test, move the ignition key (item 4
to position
"ACC"
and wait 30
seconds.
