From Wiki-DIY
| Information saved in | DME |
| Fault code | 2751 - P112D |
| Fault text | Oxygen sensor fault pump current cable before catalytic converter, bank 2 |
| Fault description | O2 Sensor Negative Current or Positive Current Control Circuit/Open (Bank 2 Sensor 1) |
| Condition for fault identification | Test condition: Lambda factor lies within this range 1.001 (K_LAVK_OBD_PLAU_LAM_MIN) and 1.009 (K_LAVK_OBD_PLAU_LAM_MAX) and the post-catalyst lambda is still outside the range 88 mV (K_LAVK_OBD_PLAU_LANK_MAX) and 879 mV (K_LAVK_OBD_PLAU_LANK_MIN) OR oxygen sensor voltage |
| . | Terminal condition: Engine running - Condition idle or part-load |
| . | Voltage condition: none |
| Condition for fault memory entry | none |
| Action in service | 1. Check plug and wiring harness on pre-cat oxygen sensor LSVK B2 (especially IP pumping current), |
| . | 2. If OK, replace oxygen sensor |
| Fault effect and breakdown warning | MIL lamp on after engine runs 2x /Small influence on drivability |
