The petrol gauge isn't working on my Peugeot 106. The fuse is ok ive had a problem finding the wires just to clean and see. Think the sender unit is stuck? Can it be taken out or would you recommend a garage? Haven't a manual to hand hence my ? many thanks ROB

The sender unit is accessed from under the left hand rear passenger seat where you will find a plastic cover. If it has just stuck I assume you think this because it always says FULL then remove the cover and thump it to see if it releases. If it alwars says empty then a fauly or corroded connector is the most likely. You can remove the sender unit but I would suggest measuring the resistance of the sender resistor externally as it could save you a lot of hassle. Wll post how to remove sender in a few minutes. Regards Peter

3 Using a screwdriver, carefully prise the plastic access cover from the floor to expose the sender unit. It is located under the left-hand cover (see illustration).
4 Disconnect the wiring connector from the sender unit and tape the connector to the vehicle body to prevent it from disappearing behind the tank (see illustration).
5 Mark the hoses for identification purposes, then slacken the feed and return hose retaining clips. Where the crimped-type hose clips are fitted, cut the clips and discard them; use worm-drive hose clips on refitting. Disconnect both hoses from the top of the sender unit and plug the hose ends.
6 On some models, quick-release fittings may be fitted to the fuel hoses; these are released by depressing their metal collars with a small flat-bladed screwdriver.
7 Noting the alignment marks on the tank, sender unit and the locking ring, unscrew the ring and remove it from the tank. This is best accomplished by using a screwdriver on the raised ribs of the locking ring. Carefully tap the screwdriver to turn the ring anti-clockwise until it can be unscrewed by hand (see illustrations).
8 Carefully lift the sender unit from the top of the fuel tank, taking great care not to bend the sender unit float arm, or to spill fuel onto the interior of the vehicle. Recover the rubber sealing ring and discard it - a new one must be used on refitting (see illustrations).
The fuse that powers the gauge is F7 and pin 2 of the 3 pin connector is the sender variable resistor. Regards Peter

Had a look but not sure if you have sent me the right info? the unit with the fuel lines makes a noise on ignition so is that the fule pump? the 2nd one has only 3 wires which i think is the sender unit. thanks ROB

robin - if your car has a carburettor, the fuel pump is probably on the engine. If injection or diesel the pump will be in the tank with the level-sender, which should have wires but no fuel lines connected to it.

Don't know whether the senders in 106 are same as in 205, but in the older car there was a vertical plastic tube in the tank containing a float, which could get stuck with fine grit in the fuel. Take it out as Peter suggests and give it a rinse in petrol or paraffin.
Wife's car ran out once because she believed the gauge reading ¼-full about 500 miles since adding any fuel!
