Engine
3.0L M57 Twin-Turbo Diesel
Diesel Particulate Filter (DPF) Regeneration Issues
- Symptoms: Check engine light, reduced engine power, increased fuel consumption, rough idling.
- Solution: Forced regeneration, DPF cleaning, or replacement. Software updates may also address regeneration cycles.
- Cost: $300 - $1500 (cleaning/regeneration) / $1000 - $3000 (replacement)
EGR Cooler Leaks
- Symptoms: Coolant loss, white smoke from exhaust, overheating, potential for coolant entering the intake manifold.
