DPF service in Riga without needless replacement.
DPF diagnostics, cleaning, repair and replacement in Riga. First we find out how clogged the filter is, and if it can still be restored, we clean it instead of replacing it straight away.
When should the DPF be checked?
A clogged DPF hurts engine performance and can cause costly damage. Watch out for these signs.
DPF or Check Engine light on
A warning light on the dashboard is the first signal that the filter needs checking.
Loss of power
The engine runs unevenly, the car pulls more weakly and fuel consumption goes up.
Limp mode
The car often switches into limp mode and limits power.
Smoke from the exhaust
Grey or black smoke means the filter can no longer cope with the soot.
Failed regeneration
Frequent or incomplete regeneration, longer starting or vibrations.
Unknown service history
You bought a used car and don't know when the DPF was last serviced.
In brief
A DPF is a diesel particulate filter that traps soot, and over time it gets clogged. At GT Garage car service in Riga, Teika, Krustabaznīcas iela 12C, we carry out DPF diagnostics, cleaning, repair and replacement. Diagnostics cost from €40, we agree the price before work starts, and if the filter can be cleaned, we don't replace it. There is a warranty on labour and parts.

Important
A car without a working DPF may not meet technical requirements and can fail the technical inspection. That's why we first look for a way to restore the filter, and only then talk about replacement.
