406 fuel tank reserve - how much is there?

this is a question I have been meaning to ask for a while now... but I was wondering if anyone knew the answer.

I have a 99 406 HDi which I tend to leave until the fuel level warning light is on before filling up. I was wondering how much fuel is left in the car once the light has appeared? There must be a reserve of a few litres... but does anyone know how much? The book says the tank is 70 litres. This is the amount I need to fill the car with if I fill up as soon as the light comes on - but sometimes I have filled it with 74 litres.

Can anyone help?

Thanks in advance.

Don't go to that petrol station again with the 74 litres :-)

My 206 light comes on and I have around 50 miles left (if I remember right) according to the computer (at around 30mpg), but this does depend on how heavy my right foot is, plus the display does go off when it gets down to around 20 miles left. If you were to say a gallon (Not US) then you should be OK

In my petrol 406 (also with the 70 gallon tank) i believe the handbook states the reserve (i.e. when the light comes on) is 7 litres.

From experience I would say that you can just about scrape 50 miles after the light comes on depending how you drive but you also run the risk of dragging all muck up from the bottom of the tank so it is probably advisable not to let it get that empty.

I do not normally go more than a few miles once the light has appeared... and to be honest, with 550+ miles between fill ups, an empty tank is usually something I am prepared for! But I was curious! I know from previous cars that you can have from 7 to 12 litres of spare capacity once the light has appeared (in a Rover 400 and the old shape Astra).

Thanks for the reply.

Hi, in my 406 petrol 2,0 2000 I usally fill up about 65 liters when my warning light goes on.. I noticed that the warning light goes on and off..first 20 km or so depending on up or downhill.. however I have never filled it up more than 67 liters, but I don't dare to run long with the light on ;=)

I would not try the 'running the car until it runs out of fuel' technique with the diesels, the TD engine is not self priming and you will have to pump by hand for ages.

550 only?

that is not a lot, i do some 1250 km with a fill up ( some 73 litres aprx) that is some 750 miles... 110hdi ( chipped to 138 bhp) maybe it is time for an injector overhaul

an empty tank is usually

I guess it all depends on how you drive!

The best I have had is about 650 miles... but that is usually a long fast run (sitting on about 95mph, or more) for 300-400 miles followed by a few days of town driving... it all depends on where I am and what sort of traffic I am in.

Where did you get your chipping done? I have looked in to it... but it will cause problems with insurance and an extended warranty I have. I did find something else about upgrading the intercooler - which will boost torque and fuel economy and make the car slightly faster... but I am a bit sceptical about all of these things. But I feel the car could do with a little more oomph!

from your reply I would guess you are not living in the UK, I used to travel from Hertfordshire to Herford in Germany via the Hook of Holland and I would fill up in Hertfordshire and would have to fill up again about 25 miles before Herford, but on returning home I would fill up in Herford and make it all the way back to Hertfordshire and have a days travel to and from work. This was not a one off but once a month for about 18 months. I presumed from this that the quality of petrol in the UK is not to the same standard as central Europe.
