Conducting leak test on fuel tank and tank
venting system
Important!
On vehicles with tank leak diagnosis modules (DMTL), do not
work with external pressurisation as the tank ventilation
system will leak under this condition.
On account of emerging fuel vapours, carry out all work in well
ventilated rooms. Or use a suitable extractor system.
Observe country-specific accident prevention and
occupational safety regulations.
Note:
The following procedure is only applicable to vehicles with the tank
leak diagnosis module (DMTL).
For vehicles without tank leak diagnosis module:
Pressurise fuel tank and tank venting system.
During the leak test with a leak detector, be sure to follow the
operating instructions of the equipment manufacturer.
Note:
Select "Tank leak diagnosis module (DMTL)" on Diagnosis and
Information System (DIS).
-
The leak diagnosis pump pressurises the fuel tank and tank
ventilation system for 30 sec.
-
If pressure is needed for longer than 30 sec., press "Activate"
button again after 30 sec.
The leak test can be carried out with a leak detector.
Possible causes may be:
-
- Tank cap leaking (check tank cap pressure relief valve).
-
- Tank venting lines leaking (fuel tank - carbon canister - tank
venting valve).
-
- Tank vent line leaking (engine compartment).
-
- Fuel level sensor flange on tank leaking.
