I drive a V50 1.6 drive, year 2010, 265,000 km. Particle filter changed at 128,000. Additive at 128,000 refilled Completely empty and additive only at 239,000 refilled, but probably not reset (see below). The (free) workshop said that I should just drive the DPF further as long as I can and not already switch at 240,000, just because it is in the maintenance plan. Now came over the HU without any problems, but AU only barely passed, since DPF probably zieml I full. Counsel of the inspector: sometimes with full gas high-speed over the highway to regenerate the DPF. Could read out with a diagnostic device (Launch CRP S7 with Volvo support) that: – The level of the additive 15/15 is – The tank is full – The tank level measurement is OFF (sprung at the beginning of the measurement between on and off – the additive pump stands OFF – supply voltage is 14,68 V error reading from the depth diagnosis: ECM-2A40 particle filter – Description: signal too high EC M-9530 Gas pedal sensor With the OBD diagnosis two errors are stored: P 193B Gas pedal sensor P2458 The error code P2458 – Diesel particle filter, regeneration time is stored if the diesel particle filter cannot regenerate and the necessary process exceeds a certain duration.Conjections: – The workshop did not reset the additive control unit before 20,000 km – I drive therefore for about 65,000 km without additive. – Therefore the DPF does not regenerate wisely Fr agen: – If additive pump is off, is this the moment value, i.e. it would start when refueling, or does this mean that it is not at all activated, so it never starts? – How do you reset the control unit for the additive if necessary? – Can I initiate the regeneration of the DPF other than by high speed (activate force conduction) ? Procedure from my point of view: – if necessary activate the additive pump by resetting the control unit – Hope for regeneration of the DPF – If there with a request for your answers or assessments. Thank you very much…
