Tip: One cause of low fuel rail pressure could be a dirty fuel module strainer.
Removing
1. Remove the fuel module (see "2111 engine fuel module (1,5i) - removal and installation").
2. With a thin-blade screwdriver, carefully pry off the strainer.
3. Remove the strainer.
4. We remove dirt deposits from the intake chamber of the fuel module and wash the body in acetone.
5. We wash the mesh filter in acetone and blow it with compressed air (from compressor or foot pump).
Recommendation: If the strainer is heavily soiled and cannot be cleaned, replace it.
Installation
Install the strainer in the reverse order of removal (see more details. "Engine fuel module 11183 (1,6i) - cleaning the strainer").
