    Default C3 error messages driving me bonkers

    Hi there ...

    ... for the last few days I've been driven to the edge of insanity by regular error messages in my 2007 C3 - "faulty sidelight", "faulty reversing light", "faulty LH rear indicator" and "faulty fog lamp" - and their accompanying annoying beeps. I checked all the lights on the car and they all worked fine. So I took it to French Car Care in East Brisbane and asked them to check it out, along with a squeak when the foot brake was applied. They found nothing wrong. The brakes were fine (probably a bit of dust, they told me) and they found nothing wrong with the computer (the error log was apparently empty). So, after handing them $143 (!) I took the car. That was Fri 11 Mar, and the error massages continue, as does the squeaky foot brake. I sent them an email this morning outlining this, and requesting feedback, but thought I'd also post on here, in case any of you guys have had a similar experience or could offer input. For example:

    - What does it mean to 'scan' the car's computer system?
    - Why would the error log be empty when I've been getting multiple messages daily?
    - If there was dust in the brakes, why wouldn't they blow it out when they checked the pads?

    These guys had good online reviews and gave me a fair quote for brake pads, and I thought they were being honest when they told me the brakes don't need replacing. Have I been shafted, and coughed up $143 for nothing?

    I'm not mechanically-minded, so go easy on me

    Cheers ~ mikethepom

    There's nothing odd about brake dust - it what happens when the pads wear. Many things, including the pads, can cause a squeal.

    The car is computer controlled, like all newish cars, and if the computer detects an error in any of the many sensor readings, it will log a code number in memory. The car has a socket that enables these codes to be downloaded, either into a generic scan tool as used by most garages, or into a computer running Lexia if you go to a Cit specialist. The meaning of the codes can be looked up, and you are on your way to diagnosing a problem. Most codes indicate mechanical or engine electrical improper readings. You appear to have none.

    Your light-related messages have something in common - they are all lights at the back. Modern cars no longer run a cable to each light. There is a single power supply cable on which a signal is imposed to switch the appropriate light. The voltage on the cable is monitored. Look closely at the boot side of your rear light clusters in case a cable is damaged or a supply or earthing connector is loose. If the problem is intermittent you'll get these popups.

    Have you changed any globes recently? It's possible to fit a single filament globe to a dual filament socket, which may cause errors. I don't know if bulb failure warnings result in a recorded fault. Probably not.

    Brake dust can contribute to brake squeal, which is probably why it was cleaned out. Hosing off the wheels and calipers might remove some more dust, but it will come back as the pads wear. Mechanics often put a blob of sealant on the back of the pad to stick it to the caliper and piston and prevent it moving about and that sometimes helps to reduce squeal. So could cutting a slot in the pad face and removing the glazed surface on the disc.

    It may be an earth problem at the lights. I was getting similar messages on my 407 and ended up putting a separate earth lead from the rear light clusters to the body.

    Thanks very much seasink, David S, pug303.
    Update: I went to Supercheap Auto this morning to fit new indicator and stop & tail light bulbs, thinking that'll fix it. It didn't. The guy at the shop looked in the manual, thinking it might be a problem with a fuse. All the fuses are listed, but nothing for external lights - what's that about? I was hoping it would be an easy fix. Bollocks! So I still have no LHR indicator, sidelight or brakelight, and error messages out the ying yang

    Have you looked at the electrical connections and wiring at the cluster yet? Is a cable/connector being intermittently open or grounded?

    In general the easiest way to buy light globes is bring the old one with you.

    I took not just the old light bulbs, but the whole car so I know I had the correct bulbs. I did look at the electrical connections - as far as I could see they looked fine. I unplugged and replugged the plastic thing with wires coming out that plugs into the light cluster. Man I'm so technical!
    I may have to bite the bullet and go back to French Car Care, even though I was in the middle of compiling a complaint about them to the OFT.

    I'm confused. Originally you said there were no issues with the lights - just messages.

    Are you now saying that there are three lights that aren't working?

    You're right - I'm sorry I didn't clarify that. Soon after I left French Car Care, the lights stopped working one at a time. First the indicator, then the brake light ...

    Almost certainly from the description, a fault in the earthing near the affected tail light.

    It's very simple and easy, and economical to add a better earth wire to just about any electrical component. It sure fixes a lot of strange problems too.
    Cheers.

    battery load test and then earth wires to affected lamps

    Check the electrical harness to ensure there is no water on the connectors. Our C3 had to have the harness replaced as the windscreen washer was watering the connector and causing one headlight not to work.
