Suggestion

In my case it's the glove box switch needs replacing which is telling the on board pc the the lid is open and therefore not securely locked .

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.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Title says it all really.... any ideas why? is it a fault or have i done something? Car is a 2002 C4 cab

POST 2Original post

usually the centre storage compartment lid not properly closed, the one between the seats

POST 3 / ORIGINAL POSTEROriginal post

Really?.. do you mean locked? or closed?

POST 4Original post

Horn will beep once if you press button twice to lock. Hand book says that if compartment lid / oddments tray is not CLOSED the horn will beep. Check out the handbook pages 14 / 15. 996 Cabriolet

POST 5Original post

Closed, I'd say. The centre storage compartments are a bit notorious for not quite closing properly and sometimes triggering your alarm. I had trouble with mine when I first got the car; the little black receiver/catch that the bar on the lid closes in to needed moving slightly as it wasn't positioned to receive the mech properly. It was done under warranty so I didn't do the job myself but I can only assume that they needed to take the centre console off to get at it - or it might be accessible through the centre storage box itself. No probs since. The horn gives a small beep when you lock the car and you've left something open. On my 2003 C2 coupe this includes the centre storage, the engine cover, the boot lid, the glove compartment or one of the doors. I'm not sure but yours might beep if the roof isn't fully located when closed...? Adrian.

POST 6Original post

Don't forget the radio contact Adrian. Have you changed the radio?

POST 7 / ORIGINAL POSTEROriginal post

Ahh... Checked all.. nothing found.. but i have changed the pcm unit... what do i need to look for?

POST 8Original post

Check that there isn't a brown&blue wire connected to the stereo mounting cage. Remove and insulate it if it is.

POST 9Original post

You mean this is a problem? Mine did this this for a year, thought it a characteristic of the car alarm system! I miss my 996

POST 10Original post

I have the same problem with mine. In my case it's the glove box switch needs replacing which is telling the on board pc the the lid is open and therefore not securely locked . The diagnostic pc it should flag up the problem.
