For notes on setting or repairing the individual systems please see the repair manuals or the relevant Service Information sheets.

After completing repairs delete the fault memory. The last page folds out; on the inside you will find the FMI

code and its meaning. The SPN for the door module – driver's and co-driver's side

– can be read out only with MAN-cats II; the SPN is not shown in the display.

If one SPN refers to the same fault/component in several control units/systems, only the generic term of the system is given. Example: "03512 EBS OBD, request, red warning lamp for diagnosis": this SPN applies to all EBS variants although they are not all expressly named (EBS2, EBS5 etc.)

Ifo ne SPN refers to different fauls/components in several control units/systems each relevant variant is named.

Example: 03099 EDC (Common Rail) fuel pressure sensor – rail pressure

03099 EDC (no Common Rail) fuel pressure sensor
