Southampton · DPF Diagnostics
What is DPF diagnostics in Southampton?
The DPF (Diesel Particulate Filter) is the most common cause of a dashboard warning light on a modern diesel car or van. Blocked, partially blocked, regeneration failed, sensor faulty, differential pressure issue — there are many reasons a DPF light comes on, and most of them are fixable without a new filter.
Common vehicles we remap in Southampton
Boostcore provides mobile DPF diagnostics in Southampton and the SO postcodes. The vehicles we see most often with DPF issues are the 2.0 TDI VW / Audi / Seat / Skoda range, the 1.6 / 2.0 CDTi in the Vauxhall line-up, the 2.0 / 2.2 CDi Mercedes, the 1.6 / 2.0 TDCi Ford, and the 2.0 dCi in the Renault / Nissan line. Each of these has its own DPF failure modes and its own diagnostic approach.
Book your DPF diagnostics in Southampton
A DPF diagnostic looks at the actual condition of the filter (loading percentage, differential pressure, regen history), the sensor readings (pressure sensors, temperature sensors, exhaust gas temperature), the live data (short- and long-term fuel trim, boost pressure, EGR position), and the stored fault codes. From there we can advise on the right action: forced regeneration, cleaning, repair, software / calibration issue, or — in the worst case — replacement.

Frequently asked questions
Why is my DPF light on?
The most common reasons are: failed or incomplete regeneration (usually a short-journey pattern), a faulty pressure or temperature sensor, a partially blocked filter, a failed EGR valve sending dirty exhaust through the filter, or a software issue preventing regen. A proper diagnostic identifies which.
Can a blocked DPF be cleaned?
Yes — most blocked DPFs can be cleaned, either in-vehicle (forced regen plus additive cleaning) or off-vehicle (specialist cleaning service). A replacement DPF is a last resort and a £1,000+ part on most modern cars, so it’s always worth getting a diagnostic before paying for a new filter.
What if my DPF light is on and the car is in limp mode?
Don’t keep driving it. A car in limp mode with a DPF fault can do further damage to the filter, the turbo, and the EGR. Get a diagnostic, and we can usually clear the fault and recover the vehicle the same day.
