FixBox d.o.o. is a DPF service and car repair workshop in Sarajevo. We specialise in exhaust aftertreatment: machine cleaning and repair of DPF and GPF filters, DOC and ASC catalytic converters and SCR/AdBlue systems, backed by advanced diagnostics and programming. We also handle all kinds of repairs, from mechanics to electrics.
We clean DPF filters with a thermal process on a professional machine that does not damage the core, and we measure the flow before and after – with a warranty on the service. When the core is cracked or melted, we repair the filter by fitting a new core.
Our customers come from all over Bosnia and Herzegovina, as well as from Germany, Austria, Switzerland and Slovenia: you can send us the filter or have the job done during your visit to Bosnia. On Google we are rated 5.0 from 31 reviews.
FixBox specialises in machine cleaning and repair of DPF, GPF, catalytic converters and SCR systems. Instead of an expensive replacement, we restore flow and the filter's factory function, with a warranty and compliance with emission standards (TÜV). We fix clogged, damaged and melted filters, faults such as P0420 and P204F00, and engine start problems.
When standard diagnostics reaches its limits, we go a step further. We use the manufacturer's original software, wiring diagrams and an oscilloscope to find the real source of the fault – even problems that diagnostic testers do not show. We repair electronics and do programming (ECU updates, flashing, adaptations) instead of just replacing parts.
Regular servicing is key to your car's longevity. At FixBox we offer complete maintenance, including oil changes, brake checks, cooling system checks and much more. Our technicians use up-to-date diagnostic equipment to detect and fix any potential problem.
