Note
t
for models with battery in engine compartment only, from November 2014, fuse 5 on fuse holder B is
t
-SB5- not present. This connection is therefore bridged. In the line (16.0 mm², red), connected to -6-, there is an inline fuse (single fuse in wiring harness coiled under the battery carrier), fuse 1 (30) -S204- (125 A).
t
Fuse 1 (30) -S204- is only accessible with the battery and carrier removed.
