VOLKSWAGEN BORA 2006 (02) PDF Document

The engine code and engine number can be found on a sticker located on the control housing. They are also provided on the vehicle data plate and stamped on the crankcase above the gearbox. If the sticker is missing, you can remove the battery carrier to read the engine code and serial number directly from the left side of the cylinder block.

When working on the fuel supply system, ensure that all wirings, including those for fuel, hydraulic, activated charcoal canister, and electrical systems, are installed in their original positions. Ensure sufficient clearance from all moving or hot components. The fuel lines are under pressure; wear protective glasses and clothing to prevent injuries and skin contact. Before loosening any fuel lines, wrap a cloth around the connection to catch any fuel, then release pressure by carefully removing the line. Prevent skin contact with fuel by wearing fuel-resistant gloves. Also, use an extraction system to remove fuel fumes when working on the fuel delivery unit if the tank is not empty.

When working on the fuel supply or injection system, adhere to these rules:

1. Thoroughly clean all joints and surrounding areas before dismantling.

2. Place removed parts on a clean surface and cover them. Use only lint-free cloths.

3. Carefully cover opened components or seal them if repairs cannot be performed immediately.

4. Install only clean parts. Unpack replacement parts immediately before installation. Do not use parts that have not been stored in their original packaging.

5. Avoid using compressed air when the system is open. Do not move the vehicle unless absolutely necessary.

Ensure the engine is at operating temperature. With the engine off, open the cap of the coolant expansion tank. Use the cooling system tester and the appropriate adapter to pressurize the system to approximately 1 bar. If the pressure drops, search for the leak and repair it. Additionally, check the pressure relief valve in the expansion tank cap by using the tester and the relevant adapter; the valve must open at a pressure of 1.4 to 1.6 bar.

Use coolant additive G 12 in accordance with TL VW 774 F. The coolant concentration should be at least 40%.

The engine oil temperature must be at least 30 °C. Remove the engine cover with air cleaner, remove the ignition coils, and unscrew the spark plugs. Connect a compression tester to the spark plug hole. With the accelerator pedal fully depressed, have a second person operate the starter until the tester shows no further pressure increase.
