Work on Pressure Regulator Valve (as of CDI3, 1600 bar system)

If you receive customer reports in the above model vehicles of fuel loss at the pressure regulator valve and/or poor engine running characteristics (shakes, knocks, surges, changes to limp-home mode, poor output, poor fuel economy, combustion noise), this may be caused by a malfunction at the pressure regulator valve (PRV) due to improper installation.

In the event of a faulty pressure regulator valve or an external leak between the rail and the pressure regulator valve, the entire rail must be replaced. Refer to WIS document: AR07.16-P-1010T (211.026) and WIS document: AR07.16-P-1010Ti (211.022).

Note:
The pressure regulator valves cannot be replaced individually due to possible imprecise installation processes in the workshop.

Note:
Warranty claims for pressure regulator valves that were replaced individually or retightened will be rejected.








Refer to possible fault codes as shown in the table.
