It bundles several relay functions of the vehicle electrical system in one plug-in unit and switches, among other things, the fuel pump via an integrated 15 A fuse as well as further engine and electrical system loads that do not run directly through the fuse strip. Depending on the model, it contains relays for the fuel pump, electronic throttle (E-Gas), fanfare horn, ETS\/ASR, secondary air pump and engine terminal 87, each with its own fuses. Typical failure symptoms are starting problems, fuel pump dropouts and rough engine running due to cold solder joints on the circuit board.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003eInstallation location:\u003c\/span\u003e Front fuse and relay box in the engine bay, behind the cover on the bulkhead.
