Signs of a Faulty CAS Module
The first step in solving any problem is identifying it. Here are some telltale signs that your 61.35-9 367 374.9-01 CAS may be in need of repair:
- Car won’t start: This is probably the most obvious sign. If you press the start button and nothing happens, or if the key won’t turn in the ignition, a faulty CAS module could be the culprit.

Steps to Repair the 61.35-9 367 374.9-01 CAS
While fixing a CAS module might sound daunting, there are actually several steps you can take to try and repair it—whether you’re a DIY-er or planning to bring it to a mechanic.
1. Check the Wiring
One of the most common issues with the CAS system comes from faulty or damaged wiring. Over time, wires can fray, break, or corrode, disrupting the communication between your key fob and the car. Inspect the wiring around the CAS module for any signs of wear and tear. If you’re comfortable working with car electronics, replacing damaged wires might solve the problem.

- Reconnect the battery and try starting the car again.
If the problem was a glitch in the system, this should clear it up.
3. Reprogram the Key Fob
If the issue lies with the key fob not communicating with the CAS system, reprogramming the fob could do the trick. The process for this varies depending on your car model, so check your car’s manual or consult with a mechanic.
4. CAS Software Update
Sometimes, outdated CAS software can cause malfunctioning. Many car brands, including BMW, release software updates to fix bugs or security flaws. Bring your car to a dealership or a trusted mechanic to check if there’s an update available for your specific module (61.35-9 367 374.9-01).
