c. If problem persists, further fuel system diagnosis is required.

Tip:

Some technicians may still wish to use a mechanical gauge to check fuel pressure.

To verify low side fuel pressure, a mechanical fuel pressure gauge may be connected in the engine compartment (figure 1).

^

Add 1 bar (14.5 psi) to value obtained from mechanical gauge to calculate adjusted gauge measurement.

^

Compare adjusted gauge measurement to value stored in MVB 103 field 1.

VAG 1318 gauge installed on a 2.0T FSI vehicle.

Tip:

MVB 103 field 1 value should be approximately 1 bar (14.5 psi) above mechanical gauge reading. This is a normal condition and does not indicate a
faulty sensor.
