Technical Analysis
The combination of P2002, P2463, and P2458 indicates critical DPF soot mass accumulation (>24 grams) and regeneration cycle timeout on Skoda 2.0 TDI engines, triggering emergency limp mode.
Expected Symptoms
System Impact
Potential Fault Sources
Workflow / Methodology
Verify supply voltage and sensor telemetry for P2002, P2463, P2458 on SKODA with multimeter at key ON.
Check DPF differential pressure with key ON: must read precisely 0 hPa (0.48–0.52 V).
Query calculated soot mass and oil ash volume in ECM live data blocks.
Execute service regeneration cycle under load following sensor replacement.

| Parameter / Signal | Testvillkor | Bör-värde (Normalt) | Avvikelse / Varning |
|---|---|---|---|
| Differenstryck DPF (G450) | Tomgång (motor >80°C) | 3 – 8 mbar | > 15 mbar (Mottrycksavvikelse) |
| Differenstryck DPF (G450) | 2 500 rpm (stillastående) | 25 – 65 mbar | > 90 mbar (Begynnande igensättning) |
| Beräknad sotmängd | Drift | 0 – 24.0 g | > 24.0 g (Serviceregenerering spärrad) |
Assessment & Action Proposal
Technical Recommendation
Repair any cooling thermostat issues, reset adaptation values, and perform a forced diagnostic service regeneration on road test. Clear DTCs.
