Please stop shouting.

Remote sensing of quantities such as levels in a tank have three principal components. The sensor, in this case the level doo-dad in the tank, the indicator - your dashboard fuel gauge - and all the wiring and whatnot in between.

Now, 406s are known to suffer from dodgy soldering in the dash department. My own fuel gauge required re-soldering twice, but that was as deep as the problem got. There are several topics on this subject, essentially you split the dash unit down until you can access the PCB then re-do all the joints.

Additionally, my gauge used to indicate about 1/4 of a tank less than I actually had when I started the car. It was only after a few minutes' driving that it crept up to a more realistic level. Based on this and the testimony of other users, I have concluded that the Peugeot make rubbish fuel level indicators >.<

If it's not the actual gauge, my next instinct would be to open up the tank and inspect the level sensor in there. It may be broken or gummed up or perhaps a connection has come loose. While you're in there, check the strainer on the fuel pick up. If parts are mucky, clean them with de-greaser. If they're damaged consider a replacement from the scrappy.

Oh, and not wanting to sound preachy but please try a little punctuation in your posts, it makes them ten times easier to decipher ^_^

hi thanks for you reply but when you sait it might be a problem with the dash soldering is this hard to remove and solve also do you know anywhere i can get diagrams on doing this thanks for your help

Hello and Welcome Heittd,

Im with Swiss on all he says,
in short Pug make the worlds worst fuel level indication kit in the whole wide world, ever!

And please less of the capital letters it does come across very shouty

Hello. What power output do you have? (90 or 110)

Welcome to the PSA mystery fuel gauge club

Hi it's a rapture I'm sure it's a 90bhp thanks Danny

You could be in luck then, the problem is it depends if it's Bosch or Siemens injection system if you can change the level sender, the Bosch has an expensive lift pump attached to it, the Siemens doesn't. You could try cleaning up the connectors on the level sender...

Is there somwhere I can find diagrams of this thanks

Hi,

I have a similar problem where sometimes the fuel gauge under-reads by about a quarter tank. It seems to be in a good mood at the moment though

Low-skill solution: I just run to about 600 miles and then fill it full, as I know I can get at least 700 miles out of a tank.

[steve_earwig]

Mine drops gradually to zero, then when I'm about to fill up I've got half a tank again

Is there somwhere I can find diagrams of this thanks

What sort of diagrams? There's these on the Coupe parts catalogue, the part numbers are a bit off sometimes and it's coup-focussed so half the dagrams are missing but should give you an idea, or you could sign up for Pug's Service Box, it's a bit involved but gets you into Pug's own parts system. Btw wiring diagrams you have to pay for, I've never even seen one so I don't know if they'll help.

Regarding the dash cluster removal and stripping, as I said in my earlier post there are many threads and guides already posted on the board. Ty the search box
