⇒ 5.4.2 Removing and installing pressure differential sender G 505 (right-hand drive vehicles)

5.4.1 Removing and installing pressure differential sender - G 505-

Method 1 (differential-pressure measurement)

Pressure differential sender - G 505- is connected via 2 pipes to the measuring points upstream and downstream of the particulate filter. Assembly overview.

Method 2 (relative-pressure measurement)

Pressure differential sender - G 505- is connected via one pipe to the particulate filter.

»Carry out the following work sequence«

Removing

Remove engine cover panel ⇒ 3 Engine cover panel.
Before pulling off, spray two hoses of pressure differential sender - G 505- with solvent.

Pull connector -2- from pressure differential sender - G 505-.
Pull hoses carefully and straight from unions (unions break off pressure differential sender - G 505- very easily).
Unscrew bolt -3-, remove pressure differential sender - G 505-.

Installing

When installing, note the following:

Specified torque for pressure differential sender - G 505- bolt, see assembly overview - Lambda probe ⇒ Item 2 (page 249)

An adaptation must be performed after renewing pressure differential sender - G 505- and/or particulate filter. (The procedure is also described under Guided Functions).

Select correct vehicle in guided fault finding.

5.4.2 Removing and installing pressure differential sender - G 505- (right-hand drive vehicles)

Pressure differential sender - G 505- is connected via 2 pipes to the measuring points upstream and downstream of the particulate filter. Assembly overview - Lambda probe ⇒ Item 8 (page 252).

Pressure differential sender - G 505- determines charge status of particulate filter.
