2008 S, 6sp manual, no sunroof. CAS needs repair/ replace- short crank no start, brake lights on after key removal, chattering foot module relays. I’ve had the FRM out and apart - no water damage or signs of corrosion. CAS removed no signs of damage. Previous owner - burned up clutch let it set for six months, let AGM battery go dead. I bought the car, it ran, installed new clutch and water pump, brought AGM back to life. A few weeks later CAS issues started.
Has anyone come up with a solution to stop CAS module sun/ heat damage? How about extending the CAS wire harness and moving it? Or using a fan and temp sensor to cool it down when hot? Dyna-Mat or foil back insulation? Anyone out there repairing CAS not just cloning. Has anyone had the same trouble again after replacing or repairing it?

 

Have you tested the brake light switch?
