Diagnostic help

Diagnostic trouble code P1585 does not indicate a fault in the true sense.

If there is less than 10 litres of fuel in the tank and a fault occurs which could be due to a low fuel level, diagnostic trouble code P1585 will be generated to indicate the cause and so prevent unnecessary fault diagnosis.

Check the wiring

Intermittent faults may occur as a result of temporary short circuits and breaks in the wiring. Jiggle the wiring at several points and in different directions to ascertain whether the wiring harness, including any connectors, is causing the trouble. Observe the multimeter, ISAT scan tool or test lamp while doing this.

Diagnostic procedure

1. Check additional diagnostic trouble codes in the Motronic system.



- Use an ISAT scan tool to obtain readouts of all diagnostic trouble codes.


The reason for one of the following diagnostic trouble codes being generated is probably because the fuel level was low at the time. Carry out a final check as described for the diagnostic trouble code in question.


• P0300, P0301, P0302, P0303, P0304.
