DPF Cleaning, repairs or replacements.

Diesel Particulate Filter (DPF) Cleaning, Repairs & Replacements in Colchester

As the title suggests it is a filter fitted (mainly) to diesel vehicles, is not unlike the filter in a modern bagless vacuum cleaner and its job is to collect particles. The Diesel Particulate Filter (DPF) collects particles from your engine and stores them in its filter, like your vacuum cleaner if it fills up to the extent it becomes blocked it cannot continue to function correctly.

In a vehicle this filling process is carefully monitored by the engine’s computer and the computer does this using not eyes but a number of sensors. With a vacuum cleaner the filter may be cleaned or replaced whereas prior to the Diesel Particulate Filter (DPF) becoming blocked beyond function, the vehicle should carry out a DPF ‘regen’. The ‘regen’ process involves the collected particles being burnt off at raised temperatures, within the exhaust, of somewhere between 500oC and 800oC and it is achieved using a variety of procedures dependant on the vehicle.

In the event, the DPF becomes blocked beyond function the vehicle will prevent the ‘regen’ process from taking place because of the potential to ignite and cause the vehicle to catch fire. If you own a diesel car then chances are you have a Diesel Particulate Filter (DPF). Over time, these soot-removing filters become clogged and should be cleaned periodically to avoid costly repairs. If the vehicle detects a fault anywhere within this system it will prevent the ‘regen’ process, for example, if the exhaust temperature sensor(s) was faulty it would prevent the computer from being able to monitor the temperature within the exhaust and control the increased fuel correctly to maintain the temperature accurately. It is more often a fault within the system than the DPF itself requiring replacement and at £500-£2000 for a new DPF this is good news for the customer.

More recently DPF’s are appearing on some petrol models as well. Exhausts are becoming very complicated with SCR also becoming commonplace which generally involves AdBlue. Most training courses on exhaust systems today are two to three days, All Trans Autos Ltd have invested in and continue to invest in the most up to date training to ensure their technicians have the expertise to both accurately diagnose DPF faults and carry out the necessary repairs. Preventing unnecessary DPF replacements whilst ensuring your vehicle remains safe.
