Complaint: Customer complains about lack of power and SVS on, DTC P1901(75) set.

Cause: DPF is clogged because of unfavourable customer driving profile (e.g. excessive short distance driving).

Production: Modified software informing customer to change driving profile will be introduced as running change. Breakpoint will be communicated upon availability.

Remedy:
In case of customer complaint ask customer about personal driving pattern. In case of unfavourable customer driving profile advice customer that the diesel particulate filter needs regeneration (cleaning). This only works when a certain profile is applied,

e.g. driving approximately 15 minutes when engine is warm. In order to avoid damages to the DPF system customer has to ensure that approximately all 500 km a proper regeneration will take place.

As of TIS 2000-DVD, version 75 a new SPS software is available which will advice the customer with a flashing glow indicator in instrument to change driving pattern (as mentioned in the service manual).
