t  Gas leak detector -VAS 6227-

t  Socket wrench e/c 19 -T10455- t  Torque wrench -V.A.G 1410- t  Torque wrench -V.A.G 1331- t  Securing ring pliers (commercially available)   WARNING Gas escaping can be a hazard! The system is pressurised! Meet the required measures: Wear protective gloves and safety goggles. Wrap a cloth around the connection before opening the system. Then release pressure by carefully loosening the connection.

Removal: –  Unscrew both hexagon bolts -1- and remove the protective cover -2-.

Altea, Altea XL 2009► –  Start the engine, accelerate to a minimum speed of 1200 rpm and wait until the fuel selection switch (Petrol / Gas) -E395- is positioned to Gas -1-.

Leon 2009► –  Start the engine, accelerate to a minimum speed of 1200 rpm and wait until the fuel selection switch (Petrol / Gas) -E395- is positioned to Gas -1-.

Continued for all vehicles –  Disconnect the connector of the valve for the gas tank -N495--arrow- .

Altea, Altea XL 2009► –  Wait until thefuel selection switch (Petrol / Gas) -E395--1- releases a fault message.

Leon 2009► –  Wait until thefuel selection switch (Petrol / Gas) -E395--1- releases a fault message.   Note The fault message occurs optically as well as acoustically. Continued for all vehicles –  Switch engine off. –  Remove the battery and its mount → Electrical system; Rep. gr.27. –  Remove air filter with its housing → Chapter.

–  Unlock and remove the plug connector -2- of the high pressure valve for operating with gas -N372--1- on the evaporator.   WARNING Gas escaping can be a hazard! The system is pressurised! Meet the required measures: Wear protective gloves and safety goggles. Wrap a cloth around the connection before opening the system. Then release pressure by carefully loosening the connection.

–  Loosen the screw connection -arrow- of the gas line -1- on the gas inlet of the filer housing using a hollow bolt.

–  Loosen the screw connection -arrow- between the filter housing and the high pressure valve for operating with gas -N372- using an 19 mm open ended spanner -T10455- and remove the filter housing.

–  Remove the securing ring -arrow- from the filter housing using pliers meant for securing ring.

–  Remove the cover of the filter housing and remove the filter cartridge. Installing –  Check the seal of the filter housing for traces of wear and replace it if necessary. –  Insert the new paper filter. –  Press the cover of the filter housing into the solenoid valve until the end and lock using the securing ring.   Note Do not damage the seal of the filter housing in the process.

–  Together with the high pressure valve for operating with gas -N372-, fix the filter housing to the evaporator -arrow-; Use the 19 mm open ended spanner -T10455- for this purpose. Tightening torques of the solenoid valve / evaporator: 30 ±2 Nm   Note t  Observe the fitting position when fitting the high pressure valve for operating with gas -N372-.

t  When installing, pay attention to the installation position of the solenoid valve. The plug connector of the solenoid valve must point to about „11 O´clock“-A-.

–  Fasten the gas line -1- to the gas inlet of the filer housing using a hollow bolt.

Tightening torque of the gas line with hollow bolt: 10 Nm –  Fasten the plug connector -2- on the high pressure valve for operating with gas -N372--1-. –  Fit the battery bracket. –  Fit the battery → Electrical system; Rep. gr.27. –  Fit the air filter together with the air filter housing → Chapter.

–  Connect the connector of the valve for the gas tank -N495-.

–  Fit the cover -2- of the valve for the gas tank -N495- and tighten the hexagon bolt -1-.

–  After completing the assembly, the Gas leak detector -VAS 6227- should be used to carry out an inspection on the screw connections -2, 3 und 4- of the LPG evaporator -1-.
