Displaying light fault when indicating left

Ok so got my 55plate C3 1.4 Desire home today and after a few trips ive noticed that if I indicate left the car pings a warning saying fault with one of the lights (lights work fine though) and the service light shows for a few seconds and then goes? anyone had this fault before or know what it might be? other than that the car seems fine all the lights work the indicator works fine it just pings this warning?

how do I get to the rear lights to check the wires at the back, front lights seem pretty easy to find access to the bulbs to check wires.

Many thanks
Tom

Sounds like it could be the COM2000 - see COM2000 a look inside as this is the indicator stalk unit and some versions do have this sort of fault.

how do I get to the rear lights to check the wires at the back

I put the procedure to remove the rear lamp clusters in the tips section

Fantastic! That's great to get some diagnostics. this weekend I'll have to get the light off and inspect the connectors, wires and bulbs and if they're fine then it looks like I'm shopping for a new COM2000.. I'm guessing they're not the cheapest thing to buy?

My boot has carpet at the sides. does that just pull to one side or is it affixed tho? as the images to remove the clusters shows plastic fairings. I am a bit of a newbie when it comes to the newer cars! I think a good thing to invest in maybe a Haynes though!

thanks for the warm welcome

The C3 Haynes manual is available from Amazon (here) and is a useful tool to have if you are wanting to do any of your own repairs or servicing.

Very expensive for a new one from Citroen. Many different models and several manufacturers of the part. Take the cowling off and look for part numbers, then try COM2000 units on eBay or investigate the COM2000 Repair Service - eBay. Some of the units can be repaired.

Mines all plastic, but carpet usually just pulls up or out of the way. The lamps will need to be changed and Citroen know this, so I would imagine the carpet is removable. By all means add to the topic on how to change the rear lamps with any extra information you find on your journey, like the carpet in the boot

While on this subject of lighting, as the coloured indicator bulbs age the amber coating flakes off or fades leaving the light from the bulb white instead of amber.
I have had this as an advisory on an mot test.
So it youre in there anyway change the bulbs if showing signs of ageing.

A persistant fault with these cars, i can take my back lights out with eyes shut, five times in 15 months. Problem is lack of tension on bulb contacts, they need support to keep in contact with base of bulb. To remove light fitting you will find a nut at top of light fitting and same at base only inside boot. Undo with 10 mil socket pull light fitting back, unclip wire conector and you will see how to unclip bulb holder from lens, you can then see how it all works and make your own repairs. Do not try bending bulb contacts as they go back in no time. You may find after doing a repair you still get a warning for some time which eventualy goes away. Would like to know if someone out there knows how to kill the beep it could be ignored then. Sorry see you have full instuctions already ( i am new to this site) but would say dont spend money as my motor is 2008 with same prob so it looks as Citroen have done nothing about this.

This is good news to know though I am starting to think that it is the stalk. I today was driving along in a rather dull area and turned the sidelights on.. suddenly I noticed that the nice brightly lit dashboard suddenly went dull... So I am guessing that's guna make driving in the dark interesting!

so I am going to have to invest in a Haynes and check out how to get it all apart to check the codes and order a new one! not really what I want to be doing with a new car but I'd rather do the work myself and save a few quid on labor

I am going to have to invest in a Haynes and check out how to get it all apart to check the codes

Haynes manual not required to get the codes. The diagnostics connector can be found in the glove box behind a flap on early cars.

To gather codes, an OBD2 can get engine codes, but Lexia tool (here) is the real master of all the ECUs of the C3. The tips for lexia tool are here


Connect an OBD2 reader or Lexia tool to the Diagnostic connector in the glove box, above the BSI fuse box.

I did come across that, though the Haynes would be more for working out how to dismantle the car to get to the bits that need fixing. but yeah that does sound like a healthy Idea to invest in a OBD or Lexia. does anyone live withing the east of england own one and fancy running a diagnostics on mine?
