On the above-mentioned vehicles, bulbs for halogen headlamps can be replaced as follows...

Headlamp cleaning systems improve visibility in the dark and prevent dazzling of oncoming traffic through stray light. On this page, find out about the structure of headlamp cleaning systems and how they work.

The ABS/ESP control lamp may light up sporadically on the above-mentioned vehicles. Error codes such as U0077, U0073, U0401 are stored in the error memory of the control unit.

Faulty injection valves could be a possible cause. After visually inspecting the wiring harness and plug connections, the fault memory of the engine control unit should be read out and deleted if necessary.

Vehicles equipped with an electromechanical parking brake can be set to maintenance mode as follows.
Before the brake pads on the rear axle brake callipers can be replaced, the electric actuator motors must be retracted.

Injection valves provide each cylinder with the required fuel and simultaneously atomise the fuel so that it can burn most effectively in the combustion chamber. Scroll through this page and find out how injection valves work and potential fault symptoms.

If the performance of the air-conditioning system is inadequate when outside temperatures are high, a faulty evaporator temperature sensor (see illustration example) may be the cause. Incorrectly measured values can cause the evaporator to freeze and block the air flow.

In the above-mentioned vehicles, incorrectly routed condensation water drain hoses of the air-conditioning system can cause a variety of electronic problems.

In the case of the above-mentioned vehicles, there can be a reduction of engine performance. The error codes P0010/P0016/P0088/P0341 are often stored in the error memory. These refer to the variable valve control or to the crankshaft/camshaft position.

The high beam optimally lights up the road in the dark. However, this light function is only used rarely so as not to dazzle oncoming road users or vehicles in front. Camera-based high-beam assistants solve this problem. 

In the case of the above-mentioned vehicle, the hybrid system, during sudden acceleration, may switch off abruptly instead of switching to emergency mode. During excessive acceleration, there may be temporary slip in the input attenuation of the hybrid transmission.

Marketing of brake products under the HELLA brand scheduled to start on October 1, 2024. 
HELLA plans to purchase TMD's 50 % share in the Hella Pagid joint venture. HELLA would therefore become the sole shareholder of what has been, up to now, a joint venture. Both companies have signed a letter of intent to this effect. Founded in 2013, the Hella Pagid joint venture sells brake components and accessories on the automotive aftermarket worldwide.
