WHAT WE DO
If you own a diesel car, you probably have a diesel particulate filter, however, you may not know exactly what this is or how to maintain it. Diesel particulate filters have been fitted to diesel-fuel cars for almost two decades now – but if not maintained, or if tampered with there could be serious consequences for your car. Here we explain exactly what they are, what they do, why you need them and how to look after them.
What is a diesel particulate filter?
A diesel particulate filter (DPF) is a filter that captures and stores exhaust soot (some refer to them as soot traps) in order to reduce emissions from diesel cars. But because they only have a finite capacity, this trapped soot periodically has to be emptied or ‘burned off’ to regenerate the DPF.
This regeneration process cleanly burns off the excess soot deposited in the filter, reducing the harmful exhaust emission and helps to prevent the tell-tale black smoke you used to see from diesel vehicles, particularly when accelerating.
Euro 5 exhaust emissions legislation introduced in 2009 to help lower car CO2 emissions effectively made DPFs mandatory, and since then, around one in two new cars a year have been diesel-powered.

DPF Removal and DPF Repairs
The diesel particulate filter captures and stores soot to lower emissions on diesel models. Without constant regeneration, the soot build-up leads to the emission of black smoke when accelerating. Understandably, this has a negative environmental impact and affects the balance of ecosystems in the Southampton area. Unfortunately, changes in legislation make DPF removal illegal and doing so could invalidate the terms of your insurance policy.
DPF removal on a car also results in a fine of up to £1,000.00 and, on a van, the penalty is as high as £2,500.00. DPF repairs provide the best option of clearing the system of soot.
Black smoke is just one indication for needing DPF repairs. Another is an alert through the dashboard warning lights. Regular short journeys driven at low speeds block the DPF sooner. Because DPF removal is no longer an option, our workshop in Southampton performs DPF repairs using active or passive regeneration practices. If neither of these processes resolves an ongoing DPF issue, we have the option of attempting forced regeneration instead.
Customers in Southampton and the surrounding areas can book in for car diagnostics, car chip tuning, ECU remapping and DPF repairs (as an alternative to DPF removal) by booking an appointment with Salek’s Motors – Hampshire’s trusted choice for garage services.
