Tenho um 525d E61 e tenho a mesma impressão.Quando carrego no botão do DTC, a carrinha fica mais segura(ou pelo menos parece) do que quando esta normal, pois assim parece que não foge nas curvas, e isto nota-se quando o piso está escorregadio ou com mt chuva.
Mas será mesmo assim ou só impressão???

Uma pequena correcção. Quando se carrega (uma vez brevemente) no botão DTC, não se desliga nada. Pelo contrário, liga-se. Liga-se o Dynamic Traction Control, tal como referido pelo Goblim, altera os parâmetros de actuação do Controlo de Tracção.
Carregando por mais que 3s, é que se desliga o DSC (Dynamic Stability Control), e aí entra-se em modo "ai Jesus".

Dynamic Traction Control (DTC) allows for sports-style driving dynamics even when DSC is controlling stability and when wheel traction is higher.
Dynamic Traction Control (DTC) is a sub-function of the Dynamic Stability Control (DSC) system that can be turned on and off. DTC has two major uses: to regulate traction and to enable sports-style driving while providing active stability control.
If the front wheels are stuck in snow and cannot spin properly, this leads to slip on the rear wheels (when they spin faster than the front wheels, generally a sign that performance has been exceeded) and DSC acts to change engine output: the power needed for forward movement is reduced. Switching to DTC has a positive effect on this situation, as traction is improved without a loss of power.
When DTC is on, it helps the driver alleviate the situation enough for DSC's measures to become effective. The driver retains complete control over the vehicle.
ynamic Stability Control (DSC) adds to safety by facilitating vehicle control even in adverse driving conditions or on tough surfaces.
Dynamic Stability Control (DSC) is the nucleus of the chassis control systems in BMW vehicles. It ensures the highest possible levels of stability when driving, and it maximizes traction of all wheels when setting off or accelerating. It is able to detect the first signs of oversteering or understeering and helps keep the vehicle safely on course, even if the tyres have varying levels of grip.
Sophisticated sensors permanently check how the vehicle is driving. Information comes a range of sensors monitoring wheel rotation, steering angle, lateral forces, pressure and yaw (degree of rotation around the vertical axis). A simulation model stored in the DSC control unit to ensure stability ("one-/two-track model") and can be compared information coming from the steering wheel and accelerator: if there is too great a difference between the model and how the vehicle is currently travelling, DSC acts to increase stability or traction.
The engine and brake management systems are targeted specifically; xDrive is also included in all-wheel drive vehicles. Reducing or increasing the engine torque or braking individual wheels can improve stability and traction. Active Steering’s integrated yaw regulation system can even help significantly reduce steering effort and the extent of DSC’s contribution to stability.
