Software Disabling of Start/Stop Function
According to research, a modern car used in urban conditions spends at least a quarter of its consumed fuel on idling: standing at traffic lights, in traffic jams, during other short-term stops. To prevent excessive fuel consumption, emissions into the atmosphere, and to improve driving comfort, manufacturers have invented a way to quickly turn the engine on and off without driver intervention. Despite saving about 10% of fuel, sometimes deactivation of the start/stop system becomes necessary.
Why the "Start/Stop" System Can Become a Problem
To allow a car to turn off and start multiple times, its engine is improved - strengthening certain components. Changes include:
- More powerful starter;
- Battery with increased capacity;
- Silent start system.
Additionally, electronic sensors participate in the system's operation. Based on their data, the ECU decides on enabling/disabling the "start-stop" function.
Despite enhanced characteristics, components cannot withstand frequent starts and usually fail earlier than in similar cars not equipped with this system. Repair of such modified nodes is typically more expensive than those not designed for start-stop.
Most importantly - the system severely impacts vehicles equipped with turbochargers. Their operation rules prohibit frequently stopping such engines, otherwise engine oil quickly loses its properties.
Advantages of Disabling the Start/Stop System
Software disabling of automatic engine shutdown and startup has its benefits:
- Positively affects the performance of components and aggregates;
- Eliminates the need to manually disable functions;
- Removes the need for further system servicing;
- Reduces engine load.
Deactivation of start-stop carries no risks for the car and does not affect the operation of other systems.
Is Disabling "Start/Stop" Legal
The ability to disable the system is provided by the design of most cars equipped with it and can be implemented using a special button. The problem is that the mode must be activated after each engine start, which reduces driving comfort. Disabling essentially keeps the button permanently in the on position.

Problem: In the case of a critical discharge of a low-voltage battery (12–48 V), the electronics prevent charging because it is dangerous with Li-Ion batteries. The manufacturer recommends discarding fully functional batteries and replacing them with new ones. This is expensive.
Problem: We received an electric car with very discharged traction batteries. The problem is typical for the Fiat 500. During idle time, the batteries discharged below the permissible level, and the car's electric motor stopped starting.

Problem: Failure of Toyota hybrid batteries is a common problem that our customers come to us with. The battery cells degrade, making it impossible for the car to operate normally.
Problem: Land Rover Range Rover Sport 3.0 SDV6 Hybrid AT AWD - the hybrid system did not work, the VBB was in emergency mode. The car was running only on diesel fuel, the low-voltage battery was not charging.
Problem: None of the car's systems were working at all, it wasn't even possible to raise it on a lift because the air suspension didn't activate either. I had to install the Porsche near the repair box on "goat" stands.
Problem: Errors P0AA6, P1F0E - high voltage charging system service
Problem: The problem with the car was the incompatibility of the Chinese GB/T standard charging system with European charging stations. This created difficulties for the owner of the Audi Q4 e-tron, since the car, produced for the Chinese market, could not charge at European stations with the required speed and reliability.

Problem: The Hyundai Kona made a rather loud noise. The customer diagnosed the malfunction on his own - in his opinion, the gearbox was the cause of the extraneous sounds.
Problem: There was water and rust inside the rail, which damaged both the needle bearing in the cover and the torque sensor, i.e. both the mechanical and electrical parts
Problem: The client complained about a knock at the bottom – it was as if a gnome was sitting there with a hammer and hitting plastic with it. However, the dwarf did not always do this, mainly after an energetic ride. Then, the sound could disappear and reappear with a new sharp push on the pedal.
Problem: Destruction (wear) of differential satellites and, as a consequence, noises (hum) when driving the vehicle.
Problem: Steering rack leakage from under the tie rod dust cover

Problem: The owner of a Citroen C4 Picasso car came to us with a complaint about poor engine performance. The car literally could hardly drive: the engine would not rev above 2000 rpm and did not develop the necessary power. Fuel consumption increased significantly. The problem lies in the car's clogged particulate filter.
Problem: We were approached by the owner of a 2017 Citroen Berlingo with complaints of a knocking steering rack.
