| Unplug electrical connector -1- on exhaust gas pressure sensor 1 -G450-. |
| –
| Carefully pull hoses off connections (take care to keep the hoses straight; the connections can easily break off exhaust gas pressure sensor 1 -G450-). |

| Tightening torque for the screw on the exhaust gas pressure sensor 1 -G450- → Chapter. |
Note | t
| Before installing, blow out hoses leading from exhaust gas pressure sensor 1 -G450- to particulate filter towards particulate filter with compressed air (hoses can become obstructed or may ice up due to condensation). |
| t
| Note that the hoses and tightly connected. |
| t
| If pressure connections are detached from particulate filter, tighten to 45 Nm. |
| Adaption must be performed after renewing exhaust gas pressure sensor 1 -G450- and/or particulate filter. (The procedure is described under Guided Functions.) |
