Information message - faulty side lamp

[jon_boy]

For the last 3 days I get a message saying 'Faulty side lamp' when I start the car, all the bulbs are working fine , no loss of brightness or anything ??

I had the same recently, turned out it was the rear number plate bulbs had blown!

[jon_boy]

No, they are both working as well, I wondered with all this rain some damp was causing a problem ??

I doubt if its damp as this would cause more current to flow whereas a bulb failure is less (no) current.

Have you checked the front sidelights really well, I find them difficult to see.

Another possibility is that a bulb is failing, I get this often on my Volvo, a few days before a bulb fails I start to get warnings. I think its accidental but useful all the same.

Another possibility is a bad connection in one of the bulb holders which will increase resistance and reduce current. Might be worth taking each bulb out and checking the base and socket for corrosion or a weak contact. This one may be related to the damp weather.

Thanks chaps, I checked the lights on my driveway around 5.00pm and couldn't see any obvious problems , they all look as bright as ever, I will get my brother to give me a hand next week .

While reading up it said some bulbs can cause problems with the trip computer readings, does any kind person known the part numbers for the correct replacement ones, there is nothing in the handbook, I have had my C3 from new and never replaced a bulb - thanks..

Well the message hasn't come up since Thursday, I did notice the service 'spanner' had been flashing and I reset that, I got a few bulbs this morning just in case..
