Injection and ignition system: Bosch ME 7.5.1

When working on the VOLKSWAGEN JETTA 2005, especially in the engine compartment, ensure that all lines (such as fuel, hydraulics, active charcoal filter system, coolant, refrigerant, brake fluid, and vacuum) and electrical wiring are routed in their original positions. Always ensure sufficient clearance to all moving or hot components to avoid damage.

The engine on the VOLKSWAGEN JETTA 2005 is removed downwards together with the gearbox. Before starting, disconnect the battery earth strap. Ensure all cable ties are replaced in the same position during installation. Detailed steps include removing the engine cover, air filter housing, battery, battery tray, and top part of the intake manifold, among other components, before lowering the assembly using an engine/gearbox jack.

For the VOLKSWAGEN JETTA 2005, the torque settings for assembly mountings are:

Engine assembly mounting A: 20 Nm + 1/4 turn (90 degrees) further

Engine assembly mounting B: 40 Nm + 1/4 turn (90 degrees) further

Engine assembly mounting C: 60 Nm + 1/4 turn (90 degrees) further

Gearbox assembly mounting A: 40 Nm + 1/4 turn (90 degrees) further

Gearbox assembly mounting B: 60 Nm + 1/4 turn (90 degrees) further

Pendulum support A: 40 Nm + 1/4 turn (90 degrees) further

Pendulum support B: 100 Nm + 1/4 turn (90 degrees) further

To remove the poly V-belt on the VOLKSWAGEN JETTA 2005, first mark the direction of rotation. Swing the tensioning device in the direction of the arrow to relieve tension, then lock the tensioning element using the locking pin T10060A. You can then remove the poly V-belt.

Push the piston ring squarely from above down to approximately 15 mm from the bottom end of the cylinder in the VOLKSWAGEN JETTA 2005. Measure the gap using feeler gauges. The gap for compression rings (top) should be 0.15 to 0.35 mm, with a wear limit of 0.8 mm. For compression rings (bottom), the gap is 0.40 mm, with a wear limit of 0.8 mm. The oil scraper ring gap should be 0.20 to 0.70 mm, with a wear limit of 0.9 mm.

Use a cylinder gauge measuring 50 to 100 mm to measure the bores on the VOLKSWAGEN JETTA 2005. Measure at three positions, both across and in-line with the engine. The maximum allowable deviation from the nominal dimension is 0.08 mm. Note that bores should not be measured while the engine block is mounted on a repair stand.

The compression pressure for the VOLKSWAGEN JETTA 2005 is as follows: New, it should be 10 to 13 bar. The wear limit is 7.5 bar. The maximum permissible difference between all cylinders is 3 bar.

When working on the fuel supply system of the VOLKSWAGEN JETTA 2005, follow these 5 rules: thoroughly clean all unions and adjacent areas before disconnecting; place removed parts on a clean surface and cover them; carefully seal open components; only install clean replacement parts; and do not work with compressed air if the system is open unless absolutely necessary.

Detailed checking involves using a pressure tester to check the fuel pressure and the delivery rate. Connect the pressure tester V.A.G 1318 to the fuel system of the VOLKSWAGEN JETTA 2005. The fuel pressure should be between 3.5 and 5.0 bar. If the pressure is not reached, check for blockages. When checking the delivery rate, the fuel pump must deliver according to the specification relative to battery voltage over 30 seconds.

On the VOLKSWAGEN JETTA 2005, open the cap on the coolant expansion tank. Then, open the drain plug on the radiator. If there is no drain plug, release the quick-release coupling and pull the coolant hose off the radiator to drain the system.

For the VOLKSWAGEN JETTA 2005, use only coolant additive G 12 (TL VW 774 F). Recommended mixtures are: For -25 degrees Celsius, use 40% anti-freeze (3.2 liters) and 4.8 liters of water. For -35 degrees Celsius, use 50% anti-freeze (4.0 liters) and 4.0 liters of water.
