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.

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

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

POST 1 / ORIGINAL POSTEROriginal post

Hi,Got Carrera 4 year 2000. I found that right front headlamp not working at all ,no indicators, no lights and also cluster all backlight not working as well(can not see current mileage)Remote key does not working too. Checked fuses, they seems to me all ok,Do you think it could be a faulty light switch or headlight control unit ecu??Please help with advice, thanks

POST 2Original post

Could be a few little problems, the light issue may just be bad connections, I'm not sure how sealed a container is at sea but it could be corrosion from the sea air. Removing and cleaning up the connectors may help for some of the issues. Ignition switches can be another problem but I would think none of the lights would work not just a single light if that was the case? Put a new battery on it as this could also be causing problems, unless you already did this?

POST 4Original post

Check all the fuses on the top row .. The A row . Remove the headlight , look at the wiring and refit it to see if it starts working. As above , the light switch doesn't tend to stop just a single headlight from working . keys inop and it probably needs new fobs coded on . Cluster fault sounds a separate fault .. do you have a volt meter that you can start to check the wiring ? If removing and refitting the headlight doesn't work then you will need to start checking for feeds and earths at the plug .
