Read evidence and context

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.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

I used the car on Friday put it in the garage, with the fuel light on, not often something I do.

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

Hello I used the car on Friday put it in the garage, with the fuel light on, not often something I do. Today decided to go for a run started the car and the gauge showed over a quarter of a tank and the range also showed around the correct miles relating to reading on the gauge. I went to fill it up and all seems ok but now I am not 100% sure. Can anyone throw any light on this? Cheers Phil

POST 2Original post

If I rarely let mine go below a quarter full, and then put some in but not full, it doesn't register it. Sorts itself when shes filled up to full again. Craig

POST 3Original post

The C4, GT3, and Turbo have a 'saddle' tank, in which the level sensor only reads the top 3/4 of the tank. From 1/4 empty, it calculates the level based on fuel consumption. There is an explanation here: http://www.porscheclubgbforum.com/tm.asp?m=346360 Not sure why it happened in your case, unless the battery was low perhaps?

POST 4Original post

I think the onboard computer is quite generous (which is quite a good thing).

POST 5 / ORIGINAL POSTEROriginal post

Thanks for the responses, the battery should not be low, however I do plug it into a CTEK to keep it in good condition, so not sure if this could have caused a problem. I think on my next outing I will fill it to the brim and keep an eye on it. I never let the light go on but had no choice on this instance. Thanks Phil
