Wiring diagrams
The wiring diagrams are assigned to the familiar function groups 00-91.
The circuit diagrams are filed according to PE number in each function group, e.g.:
The location of electrical connections, ground points and solder points are shown in the following 3 documents:
- GF00.19-P-1001DBA Arrangement of cable and plug connections
- GF00.19-P-2001DBA Location of ground points
- GF00.19-P-3001DBA Location of Z-connector sleeves (line connections in wiring harness)
All electrical components are sorted alphabetically and listed according to the abbreviations in the "Search aid for all electrical components" OV00.01-P-1909DBA . A reference is made to the wiring diagrams in which the relevant component is explained completely.
Variants of a component or the subdivision of a component into several wiring diagrams are stated in the third column.
Example:
B4/6 fuel pressure sensor high pressure valid for M642 PE07.16-P-2101DBA
B4/6 fuel pressure sensor high pressure valid for M654 PE07.16-P-2101DBD
Wiring diagram number
Kinds of wiring diagrams
The wiring diagrams are prepared as function schematics, function/system diagrams, control unit diagrams or solder point wiring diagrams, ground wiring diagrams and connector wiring diagrams.
- Function schematics
The control units and electrical components required for the function are shown as symbols. The functional connections are realized by direct lines or by the data bus.
- Function/system diagrams
All the components that are relevant to a function or system are shown in the wiring diagram.
- Control unit diagrams
Control units are represented complete with all connected components. Control units with many connections can be subdivided into several wiring diagrams.
- Solder point wiring diagrams, ground wiring diagrams and connector wiring diagrams
Solder points, ground points and electrical connections, which are not shown completely in any control unit diagram, are shown here complete with all connected components.

Wire Identification
Wire colors:
BK = Black
BN = Brown
BU = Blue
GN = Green
GY = Gray
OG = Orange
PK = Pink
RD = Red
TR = Transparent
VT = Violet
WH = White
YE = Yellow

Variants
The wiring diagrams can contain variants that are framed to identify them and provided with an abbreviation "U..." or "Code...", or are marked with a time limitation, a vehicle model designation, an engine model designation, a transmission model designation or a vehicle identification end number. The variants identified by the abbreviation "U..." or "Code..." are listed in the legends.
The vehicle identification end numbers or time production data stated apply to the market launch of standard production.
Preproduction vehicles can have a lower vehicle identification end number or an earlier production breakpoint.
In case of changes that come up after the market launch of standard production, the variants can be designated with 1 and 2.
Logical combinations of variants are represented as follows:
- »And/or« combination
Validity elements are presented one below the other; the variant is valid if at least one of the validity elements applies.
- »And« combination
Validity elements are presented indented one below the other; the variant is valid if all the validity elements apply.
Signal and terminal designations
The signal and circuit designations used are explained in the section "Abbreviations of signal and circuit designations for wiring diagrams" OV00.01-P-1001-28DBA .
Special features in presentation
It is possible to select certain areas in the wiring diagram and consequently to switch to other documents or wiring diagrams.
