Volkswagen California 2.0 TDI 4Motion Automat - 150 HP

Start-Stop system disable

The Start-Stop system automatically shuts the engine off when the vehicle stops, for example at traffic lights, in order to reduce fuel consumption and emissions. In practice, however, it often feels intrusive, slows down take-offs, reduces driving comfort and unnecessarily strains the starter and battery. Disabling this function provides smoother and more natural vehicle behavior without constant engine stop-start cycles.

Disabling the Start-Stop system may lead to a slight increase in fuel consumption and emissions, especially in city driving.

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.

Speed limiter disable

Is the top speed limiter preventing you from using the car's full performance potential? We offer its deactivation so the vehicle can reach its true maximum potential without artificial restriction.

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.

Swirl flap disable

Swirl flaps in the intake manifold are designed to improve combustion at low load, but over time they often become clogged with carbon and may cause irregular engine operation or mechanical problems. By disabling them, we eliminate the risk of seizure or damage and ensure more stable and reliable engine operation.

For maximum reliability, we also recommend mechanically blanking the flaps.

AdBlue disable

Do you want to reduce operating costs, are you tired of constantly refilling AdBlue, or are you dealing with repeated failures of this system? By disabling AdBlue injection, we remove these concerns and help you avoid often unreasonable and repeated repair costs that can easily reach thousands.

Active exhaust flap disable

The active exhaust flap regulates exhaust gas flow and thus also the vehicle's noise level. In some cases, however, it limits the sound character or behaves unpredictably. By disabling it, we ensure a permanently open exhaust, a stable sound and a more natural character without electronic intervention.

Disabling the flap may lead to increased noise, especially under acceleration. The vehicle may therefore no longer meet legal noise limits for regular road use and this should be taken into account.
