10 Remove hoses (3, 4) from pressure lines (7, 8) and remove diesel particulate filter differential pressure sensor (B28/20) and OBD diesel particulate filter differential pressure sensor (B28/22) With engine 642.898
NOTES Do not remove hoses (3, 4) from diesel particulate filter differential pressure sensor (B28/20) and OBD diesel particulate filter differential pressure sensor (B28/22) to prevent damage.
IMPORTANTInstallation:  Replace hose clamps.		  
11 Install in the reverse order    
DANGER Risk of accident  caused by vehicle starting off by itself when engine is running. Risk of injury  caused by contusions and burns during starting procedure or when working near the engine as it is running Secure vehicle to prevent it from moving by itself.
Wear closed and snug-fitting work clothes.
Do not touch hot or rotating parts.		 AS00.00-Z-0005-01A
12 Test run engine and check exhaust system for leakage in area of diesel particulate filter differential pressure sensor (B28/20) or OBD diesel particulate filter differential pressure sensor (B28/22)
