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