Vehicles which require this Recall Campaign to be completed will show it as “Open” when checked either in AIR, the “Service Menu” of DCSnet (Dealer Communication System), ISPA Next or Warranty Vehicle Inquiry.
The 48-Volt battery cable connections to the starter / generator (SGR) may not have been assembled to specifications. Over time, this could lead to increased resistance at the connection(s) and, in rare cases, a thermal event.
Check the M8 flange nuts and cable connections on the SGR. If necessary, replace the flange nut and torque to spec.
Check B+/ B- connections cable for play (1).
If the connections are tight and the cables cannot be moved by hand–
- No further action is necessary
If there is play in the connection to the SGR –
- Deactivate the 48 V electrical system (Repair instruction REP-TAT-P-6124-18-B47_48V)
- Remove and discard the flange nut on the B+ or B- cable.
- Install a new flange nut so that it’s carefully started by hand to avoid cross-threading
- Torque to 19 Nm
Only use and invoice the part numbers below that apply.
Performing a part number look-up in ETK (EPC) by VIN or model in place of using/invoicing the following part numbers may result with the wrong part numbers being invoiced and installed, this could delay the payment of the claim.
