Hot start repair

Hot start repair

Some vehicles may suffer from hot start issues, where the engine cranks for too long, starts reluctantly or behaves irregularly once warm. By adjusting the software, we correct unsuitable start map settings and ensure quick, smooth and reliable starts even with a warmed-up engine.

This modification does not solve issues caused by a faulty fuel pump – in such cases, a mechanical repair is required.

EGR valve disable

EGR valve disable

The EGR valve (exhaust gas recirculation) is designed to reduce emissions, but in practice it often causes intake contamination, power fluctuations or a higher failure rate. By disabling the EGR, the engine runs cleaner, throttle response improves and the risk of carbon buildup is reduced.

Disabling the EGR may lead to faster DPF clogging and increased emissions.

DPF disable

DPF disable

Are you struggling with a clogged diesel particulate filter, frequent regenerations, loss of power or increasing fuel consumption? If the cost of DPF repair or replacement is unreasonably high, we offer a software DPF disable that removes these issues and restores reliable, smooth engine operation.

Removing or disabling the DPF makes the vehicle technically unfit for road use and it will not pass a roadworthiness inspection.
