Particulate Filter Over Temperature (Bank 1)
A temperature sensor at the diesel particulate filter (DPF) on bank 1 has exceeded the safe limit — typically during a runaway regeneration. Continued operation can melt or crack the substrate.

Possible causes
- Excessive soot load triggers runaway regeneration high
- Post-injection over-fueling during regeneration medium
- DPF temperature sensor reading drifts high low
Symptoms
- Check engine light or DPF warning light on
- Power loss / limp mode
- Increased fuel consumption
- Failed forced regeneration attempts
Inspection / repair
- Difficulty: hard
- DIY: shop recommended
- Estimated cost: 200–4000 €
- Estimated time: 1.5–8 h
- Component: diesel particulate filter
- Component: dpf temperature sensor
- Component: regeneration strategy
- MIL / check engine light
- emissions-relevant
- limp mode possible
