The Mercedes-Benz 722.9 transmission, also known as the 7G-Tronic, is a sophisticated 7-speed automatic transmission introduced in 2004. Central to its operation is the Transmission Control Module (TCM), integrated within the conductor plate. This component manages gear shifts, ensuring optimal performance and efficiency. Over time, however, the conductor plate can develop issues, leading to transmission malfunctions.

Common Symptoms of Conductor Plate Failure: 

• Erratic Shifting: Delayed or harsh gear changes.
• Limp Mode Activation: Transmission remains in a single gear to prevent damage.
• Diagnostic Trouble Codes (DTCs): Codes such as P0717, P0722, and P2200 indicating sensor issues.

• Hard start
  
• Rough engine operation during cold
• Low injector circuit codes
  
• Fault codes: P0611, P1378, P0261, P0264, P0267, P0270, P0273, P0276, P0279 & P0282
  

The ELV (Electronic Steering Lock) in BMW vehicles is a security feature that locks the steering wheel when the car is turned off, preventing unauthorized use. It works in conjunction with the CAS module to ensure the steering lock disengages only when a valid key is detected, enhancing theft prevention.

Symptoms of a failed ELV include: 

• Yellow or red steering lock on dash
  
• AOAA CAS System Malfunction
• A115 ELV Steering
• AA116 CAS Critical Status ELV Steering Lock
• A119 Power Supply Electronic Steering Lock in the CAS
