Bosch injectors, with OEM reliability only will fail from fuel system contamination. With fuel system contamination we recommended that the low pressure fuel pump sock is replaced, the low pressure fuel line is flushed, the high pressure fuel pump is removed and inspected, the high pressure fuel line is flushed and all four injectors are replaced.
Not for use on any other vehicle, including the FK2.
