A blocked DPF will often result in some of the following BMW specific diagnostic trouble codes (DTC) to be generated:
480A Particle filter system
481A Particle filter system
4530 Charge-air pressure control, control deviation
4010 Exhaust backpressure sensor before particulate filter, signal
4D00 Exhaust backpressure sensor, signal
452A Info particulate filter system
4166 Particulate filter system
4CF3 Exhaust backpressure sensor, signal
First we physically remove the troublesome filter. We only remove the internal core, the outer DPF chamber is left in place along with all sensors. Therefore, the vehicle will still appear to have a DPF fitted and the vehicle will appear unmodified.
Once the physical removal has been carried out, the ECU (Electronic Control Unit) is reprogrammed (remapped) and any DPF related structures removed from the vehicle’s software. This will prevent the vehicle sensing the missing filter and will prevent future DPF regeneration and warning lights. This is the most important aspect of the removal process and it is vital that the ECU is reprogrammed correctly or DPF issues will continue. When carrying out this process we can also remap the ECU for better performance and fuel efficiency, this is normally free of charge with our DPF removal service.
DPF Removal is not only a cost-effective solution but it also boasts the following advantages:
- Increased performance
- Increased efficiency (MPG)
- Less turbo lag
- Reduced maintenance costs
