Remove/install

1

Disconnect electrical connector (3).

2

Remove nuts (2).

3

Open clamps (5) and remove pressure hoses (4) from pressure lines at diesel particulate filter.


Do not remove pressure hoses (4) from diesel particulate filter differential pressure sensor (1).
Hairline crack formation occurs at diesel particulate filter differential pressure sensor (1) due to release of clamps at diesel particulate filter differential pressure sensor (1); malfunctions can thus arise.

 Installation: Observe assignment of pressure hoses (4), replace clamps (5).
