Hazard

In the mechatronics of 7-speed DSG automatic transmissions, some units have insufficient wall thickness due to improper machining precision of the accumulator mounting housing. When large hydraulic pressure fluctuations are repeatedly applied during starting or congested driving conditions, micro-cracks develop in the housing, causing hydraulic pressure to drop and warning lights to illuminate. Continued operation in this state may result in complete loss of driving capability.

7速DSG型自動変速機のメカトロニクスにおいて、アキュムレータ取付け部のハウジング加工精度が不適切なため、厚みが不足しているものがある。そのため、始動時や渋滞走行などの大きな油圧変動が繰り返されるとハウジングに微細な亀裂が発生し、油圧が低下するとともに警告灯が点灯して、そのままの状態で使用を続けると、最悪の場合、走行できなくなるおそれがある。

Remedy

All vehicles will have their automatic transmission control computer reprogrammed with the corrective software. However, some vehicle models require additional preparation time for the corrective software, and repairs will be performed as soon as it becomes available. If a hydraulic pressure drop fault code is stored, the mechatronics unit will be replaced with a new one.

全車両、自動変速機制御コンピュータを対策プログラムに書き換える。 ただし、一部の車種において対策プログラムの準備に時間を要するため準備が整い次第対策をおこなう。 なお、油圧低下の故障コードが入力されている場合は、メカトロニクスを新品に交換する。
