I have had the cluster pod out before to change a few illumination bulbs and tried to slide the clips to separate the backing but they were really tight.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I have searched around on the web and Rennlist and have not found any information relating to my specific question... Is it possible that if the green cruise control bulb on the instrument panel is burned out, will it affect the function of the cruise control? I have replaced both the clutch and brake switch with failed results. They were not that expensive, so I tried them. I bought a Durametric later on to diagnose another CEL lamp and it displayed a cruise control bulb fault. Is the system really that sensitive to a indicator bulb? I am the third owner and the CC has never worked (why do I even want this to work on a sports car?). It is not a huge problem that it is not working, but I am a perfectionist and the system must be operational. Secondly, If the bulb does affect the CC system, how does one specifically pull the back of the cluster apart? I have had the cluster pod out before to change a few illumination bulbs and tried to slide the clips to separate the backing but they were really tight. Are they supposed to be that tight to the point of forcing them so much they feel like they will break? 1999 996 Carrera 4 Manual Trans VIN: WPOAA2997XS624889

POST 2Original post

What code did it throw? Double check the brake lights.

POST 3Original post

If all THREE brake light bulbs are not INCANDESCENT and working the CC will not work.

POST 4 / ORIGINAL POSTEROriginal post

Code: "P1576 -Porsche fault code 274 - Cruise control readiness light via CAN exceeds limit value" I have checked all tail lamps on the rear of the car. All are functioning incandescent bulbs within the wattage specs.
