Vauxhall - Illumination of the malfunction indicator lamp | HELLA

If a customer complains about the above error, this could be caused by the diesel particulate filter. Not least of all, this problem would also cause a lack of power. This complaint has been observed even in vehicles that are used for short trips with many cold starts. The error code "P1901- Particulate Filter Pressure Sensor" could also be stored in memory. In this case, proceed as follows:

- To rule out other error sources, all relevant systems and components should be tested. During the testing, also pay attention to the wiring and check for problem-free contacts (corrosion in the plug connections).

- If no errors are discovered in these parts, the particulate filter should be regenerated by hand.

- To prevent subsequent damage, the particulate filter must be cold.

- The regeneration process produces high temperatures in the exhaust system! For this reason, do not park the vehicle on combustible surfaces.
