| Remove/install | ||
| Notes on self-locking nuts and bolts | ||
1 | Switch off ignition | ||
2 | Remove NOx sensor controller unit (A113a1) at holder (4) | The NOx sensor controller unit (A113a1) and NOx sensor (A113b1) create a unit and can only be removed together. | |
The NOx sensor controller unit (A113a1) must also be removed first otherwise the electrical line (2) could be damaged by twisting when removing the NOx sensor (A113b1). | |||
| |||
3 | Disconnect electrical line (6) at electrical connection (1) and detach electrical line (2) out of brackets | ||
4 | Remove NOx sensor (A113b1) | Only place tool on hexagon since the component is very sensitive and can be easily destroyed. | |
Installation: Coat thread on NOx sensor (A113b1) with lubricant. | |||
| |||
5 | Install in the reverse order |
