Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion
Highly unlikely that you disturbed anything when you changed the battery, but the only way to check would be to remove the battery and plate, and take a look.

Suggestion
I thought it might be a C4, which has the "saddle" tank and gives false readings when the battery is disconnected when the fuel level is low.

Is it a coincidence or have I done something while replacing the battery??

Had to change my battery a few weeks back and have recently noticed that my fuel light no longer illuminates at 50ish miles to go (according to OBC).

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hello, I'm a bit confused by this one. Had to change my battery a few weeks back and have recently noticed that my fuel light no longer illuminates at 50ish miles to go (according to OBC). It now comes on as it goes ---??? Is it a coincidence or have I done something while replacing the battery?? Fuel Gauge works perfectly. Thanks. [8|]

POST 2Original post

C2 or C4, and have you filled the tank (with more than 20 litres or so) since the battery went flat?

POST 3 / ORIGINAL POSTEROriginal post

C2 and half filled it last night, probably most I've put in since, everything lights up as normal when you turn ignition on??? [8|]

POST 4Original post

I thought it might be a C4, which has the "saddle" tank and gives false readings when the battery is disconnected when the fuel level is low. A bit of a mystery. I guess you could try pulling the instrument cluster fuses (B1 and B10) in an attempt to re-start it. Other than that, I can only suggest a diagnostic check, to see if any fault codes are stored in the cluster.

POST 5 / ORIGINAL POSTEROriginal post

Hiya, been living with my fuel light not indicating correctly, and recently worked out it is an intermittent fault sometimes it lights up others nothing at all even when --- indicated on my OBC display. Have had a quick look under the bonnet near the battery but don't know if any of the wiring there is from the fuel tank low level light???

POST 6Original post

The fuel tank and pump/level connections are under the plate which the battery sits on. Highly unlikely that you disturbed anything when you changed the battery, but the only way to check would be to remove the battery and plate, and take a look.
