Carrera 4 and Carrera 4s owners.....

FYI

This may be common knowledge, but I have only just found out the following regarding the fuel tanks on the C4 and C4S models.

It seems that the 4-wheel-drive carts have an unusual shaped fuel tank, which incorporates a 10 litre reserve tank, and it would appear that ocassionally the float that measures the amount of fuel left in the tank can get 'stuck', thereby showing you as nearly out of fuel when that is not the case.

This explains an issue I had a few months ago where I did a 'splash and dash' putting in just enough fuel to get me home (as I couldn't find a station with Shell V-power) but despite adding 10 litres or so, the range on the computer and the fuel gauge did not budge. I assumed a faulty pump but when I did find a Shell station and filled up, doing the sums showed that I clearly HAD added those 10 litres previously.

Once the car is re-fueled to the brim all is fine, as the float can release itself. I'm sure there is a more technical explanation for exactly what happens, but that works for me!! I've only had these 2 issues in almost 2 years of owning the car, but not sure whether this is an issue that has confused anyone else?

Cheers

Apparently the fuel guage and fuel range calculator on all 997s are inaccurate when the fuel tank is below half full

This is what I was told when my 997 ran out of fuel despite having an indicated range of 18 miles!

Oddly enough, I have never had the same thing happen since, even when dipping below the 10 mile barrier when playing fuel light bingo!
