Citroen C3 Aircross fuel sender

[BadBoyBubbie]

Ok I’ve had a fault code pop up few times P0463 the first relates to incorrect fuel tank level sensor high input and the other is U0422 which I presume is BCI telling ECU there an incorrect reading. This became a regular occurrence every few starts. Now I located the area, took out back seat and found the fuel sender bay was absolutely filthy, so before trying to get another part would clean it out, then I let the car go into sleep mode disconnected the connection cleaned with contact cleaner and put it together on and off about 5 times to clean the contacts. Then resprayed again with contact cleaner again to flush let it dry, connected. Removed codes, drove for about 250 miles over a week and everything was lovely. The light appeared again , so checked same codes. Now I’ve been looking for parts in the U.K. and all these new senders are four pin and mines a six pin. Seen some second hand ones but my problem is, could it be the connector and not the actual Sender fuel tank level sensor. Any help would be appreciated, car drives great, even with light on, no limp modes, no fuel gauge issues that are really noticeable. It has me head cabbaged. If I need a sender does anyone know where to get a 6 pin variant that won’t cost me an arm and a leg. Thanks. Reg of the car is NK18 TCO 1.2l 110bhp petrol.

It might be best to read the number written on your original piece. According to Autodoc your car uses a fuel sender that has a 4-pin connector. And the C3 Picasso 1.2 THP uses a 6-pin connector.
