The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

The label on the throttle body fitted to your car should show the number 09128518 or 5WS91703. The model name alone (Opel Astra G, Astra H, Corsa C, Meriva A, Zafira A, Vectra C, Signum) is not enough – throttle bodies with other numbers were also fitted to these cars.
Common throttle body faults
When the throttle body in a Opel starts to fail, the most common signs are:
- worn track in the throttle position sensor – fluctuating revs, jerking on light throttle,
- carbon deposits on the throttle plate – rough idle, engine stalling when coming to a stop,
- in electronic throttle bodies: failed motor or gear drive – limp mode, reduced power, engine warning light.
If cleaning does not help and diagnostics point to a throttle body or position sensor fault, replacement with a part carrying the same number is usually required. After fitting, many cars need an adaptation according to the vehicle manufacturer's procedure.
