Fuel Injection

[Guest cobhorse]

Hi,

New to forum looking for info regards my wifes c3 1.4 2003 just been serviced in the garage and has afault on number 4 injector garage states you need to change them all is this correct. Out of curiosity how difficult is it to change the injectors and are there any specilaized tools required as i am fairly good mechanically when i can be bothered.

I guess the engine management light has come on, possibly after rain. A common fault where it drips under the washer jets and on to the injectors causing them to fail. Happened to our car and 2 of the injectors were replaced by the dealer under the warranty. Have a search on the C3 forum pages. To prevent it occurring again, seal the washer to bonnet hole with a sealant and maybe change the washer piping to a rubber type that gives a better grip to the jets. You can also seal the injector coil holes with sealant to prevent water getting in. I would not think they are difficult to replace, it is covered in the Haynes manual although they give it 4 spanners for difficulty.
