▀▄ eas | Quidzel Traffic Jam Assist (TJA) retrofit for i3 now available

     Featured on

We are happy to announce the release of Quidzel Traffic Jam Assist Modules (TJA) for i3 are in stock and ready for installation or shipping.

BMW Traffic Jam Assist (TJA) is a driver aid system that performs lane keeping along with adaptive cruise control in limited scenarios, specifically highway traffic situations where the system is adept at following the car ahead at low to medium speeds, controlling steering, accelerator, and braking inputs. However, BMW has not offered this feature in the US market until just recently, even though many recent models with active cruise control already have the software and most of the hardware required. Specifically, BMW adds a capacitive steering wheel, sensor module, and wiring that is used to detect hands on the steering wheel and presume that if the driverís hands are on the wheel, the driver is in control of the vehicle. Some people have bought the steering wheel & other hardware costing up to $1000 and successfully retrofitted their USA cars with TJA by coding the system modules to include option 5AR. The hardware isnít commonly available in the USA, and requires airbag removal, etc.

The Quidzel Hands On Detection test emulator communicates with the car as if you had retrofitted the capacitive steering wheel. This small module installs in about 2-3 minutes, allows you to test the TJA functionality by coding the car for the new functionality, and is fully reversible. It is easiest to apply the code as a one-shot VO FA change across all the modules, as different cars have different modules. The initial hurdle to coding your car is a little steep, so you might ask for some help from someone advertising BMW retrofit coding services.

It must be said that you must remain attentive and in control of the car. You are responsible to monitor and correct your carís driving Ė you will find that TJA is not autonomous driving and its technical ability is limited. To take advantage of this feature, you already must have active cruise control and are aware of its limitations Ė this adds steering assistance/control with similar limitations. Our HOD test emulator emulates the capacitance measurement, enabling BMW Traffic Jam Assist on your BMW vehicle with ACC (option code 5AT).
