Reported cause
Thing is, I reckon this was caused by the sight of his sideburns, not the broken down Turbo.
Leading evidence: 'sight of his sideburns, not the broken down turbo' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'sight of his sideburns, not the broken down turbo' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Fill ups, sometimes less' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Interestingly the fuel consumption on my targa was 20mpg before I fitted the PSE, it then dropped to 16Mpg.

I get about 250 miles between fill ups, sometimes less.

I regularly run the car down to --- on the gauge, at which point it varies between 58-63 litres.

Seriously on a long run I would expect a range of 300+ miles
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.

Does the tank capacity vary between the C2 C4 and TT. (996 models) I always fill up when the range indicates around 30 miles left and in the C2 Targa it would cost me £55ish. In the TT it is under £45. I know petrol has dropped in price but not by 20%.
Interestingly the fuel consumption on my targa was 20mpg before I fitted the PSE, it then dropped to 16Mpg.
Consumption on the TT is currently 16.5mpg and I have been exploring the power on it.

My computer always suggests that i've got a long range ahead after a fill up but after about 10 miles its ambitious estimates seem to fall by about 30 miles! LeMans tank range is a concern of mine!

Mine often starts up at 390-400 miles. Got about 360-370 from a tank on the way up through France on the Peage. Would have been better but Kate drove for some of it and she has a heavy foot!

Chris Harris wrote an article about this in GT & PP mag. He had a 996 TT and his one complaint was the fuel capacity

I'd missed this thread up to now. Chris Harris' complaint wasn't so much the fuel capacity, more the fact that the 4WD cars' fuel gauges are only accurate for the first half of each fill. After that the the computer calculates the remaining fuel based on the thirst during the initial stages (that's Harris' account anyway).
Have a look at GT & PP Aug 06 - it's an amusing article. Poor Chris had about 30 wrists extended from car windows as he sat at the side of the M4 having run out of fuel - all too visual an image! Thing is, I reckon this was caused by the sight of his sideburns, not the broken down Turbo.

I regularly run the car down to --- on the gauge, at which point it varies between 58-63 litres. Regarding the 4wd partial refill, if you put less than 1/2 tank in when the low fuel indicator is on the needle will not move....unless you do a few laps of Silverstone, I partially filled the car during a trackday and the needle didn't move however a few hard corners later the needle 'nudged' into it's correct position.

Actually, I read Chris Harris saying that LHD have bigger tanks in GT Purely Porsche too - not my left hand drive or any other LHD in Japan for that matter.......Are they different in Germany I wonder.....Somehow doesn't seem viable to me....

I think it was an option on LHD cars to get a larger tank.
The standard (and only one on RHD cars) is 64 litres.
I have never managed more than 60.
64 litres is the same for C4S and C2.
The fuel gauge does not reset unless you more than half fill it. Just putting a tenner in will not show on the guage.
Normally I fill up at 50-55 (11-12 galllons).
Remaining range at fill up varies from 10-50 miles depending on amount remaining and whether the fuel consumption before filling was 15mpg or 25mpg.
I get about 250 miles between fill ups, sometimes less.
Range is an issue, if you want to go a long way.
