What could be the reason for the Mercedes-Benz GLA200 not responding when shifting gears?
2 Answers
Mercedes-Benz GLA200 not responding when shifting gears may be caused by issues such as transmission valve body failure, transmission shift mechanism failure, or internal friction plate failure in the transmission. Below is some relevant information about the Mercedes-Benz GLA200: 1. Exterior: As an entry-level crossover SUV model, the Mercedes-Benz GLA reflects the design style of the Mercedes-Benz A-Class. The new car's headlights feature the latest design from the Mercedes-Benz family, incorporating LED daytime running lights as always. The raised lines on the engine hood give it a dynamic and sharp look. In terms of dimensions, the Mercedes-Benz GLA measures 4417mm in length, 1804mm in width, and 1494mm in height, with a wheelbase of 2690mm. 2. Powertrain: The Mercedes-Benz GLA200 is equipped with a 1.6T turbocharged engine, delivering a maximum power of 115kW and a peak torque of 250Nm.
My GLA200 also experienced a situation last week where there was no response when shifting gears. The mechanic conducted a detailed inspection and found that the micro switch in the electronic gear shift mechanism was stuck. Nowadays, these electronic gear levers in Mercedes are quite delicate—either the internal sensor in the shift mechanism has poor contact, or the brake light switch is faulty, causing the system to fail to receive the brake signal. Another possibility is that the wiring connector of the gear lever assembly has become loose, which can be seen by opening the center console. The transmission control module also has a high probability of failure, especially in areas with heavy rainfall where it’s prone to moisture. The mechanic said it’s essential to use Mercedes’ specialized diagnostic computer to read the fault codes—guessing won’t fix it. It’s recommended to go directly to a 4S dealership for testing; they can diagnose it accurately with the XENTRY computer.
