This vehicle is not fitted with ADAC at the moment.
If another bargraph is illuminated, refer to the fault finding for that bargraph.NOTES
If your vehicle has ADAC,
this method of fault finding will not be of use for this fault.
This bargraph is often illuminated or flashing in the following cases:
-Air conditioning compressor command mode G12*.
-Fault on fuel pump relay circuit.
-Other cases, which have not yet been noted, may well exist.

Connect the bornier in place of the computer and check the insulation and continuity of line 51 on the
computer.
Repair if necessary.
Check that the vehicle has air conditioning and if it is not fitted with air
conditioning, deal with the other bargraphs first.
Engine running, select the air conditioning function.
NOTES
If the fault persists, refer to the air conditioning fault finding.
