📋 Procedure

1. Connect remote controlV.A.G 1348/3 A with adapter cableV.A.G 1348/3-3 to connection of fuse 30b (enlargement).
2. Insulate second free flat connector of adapter cableV.A.G 1348/3-3(arrow) using commercially available insulating tape.
3. Connect battery positive terminal of remote controlV.A.G 1348/3 A to positive terminal (+) of battery.
4. ⚠ The fuel line is under pressure.Risk of injury to eyes and skin from fuel.Wear eye protection and protective clothing to avoid eye injuries and skin contact. Before loosening hose connections, wrap a cloth around the connection. Then release pressure by carefully opening the connection point. — Place a cloth around the union of the fuel hoses and separate fuel supply line (3). [Note: Press in buttons on hose couplings to do this.]
5. Connect pressure testerV.A.G 1318 with adapterV.A.G 1318/17 and V.A.G 1318/23 as well as adapterV.A.G 1318/11 and hoseV.A.G 1318/16 to fuel supply line as shown.

6. Hold hoseV.A.G 1318/16(1) in a measuring container (2) with a volume of at least 1000 cm3.
7. Operate remote controlV.A.G 1348/3 A until fuel flows.
8. Empty measuring container before making measurement.
9. Operate remote control for 15 seconds for the measurement. The delivery rate must be at least 800 cm3/15 s.
10. Check fuel lines for possible restrictions (kinks) or blockages.
11. Raise vehicle.
12. ⚠ The fuel line is under pressure.Risk of injury to eyes and skin from fuel.Wear eye protection and protective clothing to avoid eye injuries and skin contact. Before loosening hose connections, wrap a cloth around the connection. Then release pressure by carefully opening the connection point. — Place cleaning cloths around separating point (arrow). Pull fuel supply line off filter input. [Note: Press in button on hose coupling to do this.]
13. Connect pressure testerV.A.G 1318 with adapterV.A.G 1318/17 and V.A.G 1318/23 as well as adapterV.A.G 1318/11 and hoseV.A.G 1318/16 to fuel supply line as shown.
14. Repeat delivery rate check.
15. Renew fuel filter .
