  • [Corsa D] Error code on Odometer?

    Got a 2007 Design, and every so often when I start the engine, in place of my trip mileage I get a number '3' and just below that what looks like a headlamp icon. I've tried google and the manual but cannot find out what this means. Anyone have any idea?

    Automatic headlight levelling system fault (illuminates yellow) according to this

    Unsure as to what the number could be referencing though, sorry

      With manual levelling adjustment you normally have a number indicating the current headlamp height level (eg lower than normal if you are towing or have a heavy load. ) Maybe if the auto levelling stops working the number shows the level it is stuck on. ?

        Bugman is correct, the number represents how high or low your headlamp height level is set to. I believe the range is from 0 - 3. I always have mine set to 2 so every time I turn the car on it quickly reminds me that the headlamp height is set to 2 and then disappears and shows the mileage screen as usual.

        Try change your headlamp height (there should be plus and minus button(s) near the headlight knob) and see if the number changes. I have attached a picture below.

          Thanks for the replies.

          tahmid, is that not the display brightness? Think the headlight height is the one at the bottom!

          It only happens intermittently which is odd.

            Ahh yes, sorry my bad. You are correct, they are the bottom ones.

            My Corsa does it intermittently too, so maybe just a Corsa problem

              I dont know how automatic levelling works but it must be smart enough to ignore gradient. So it probably measures the stance of the car by measuring at the back axle vs the floor of the car . And unless the level is constantly adjusting it must be able to ignore the car simply bouncing while in motion and possibly take an average over several measurements.
              It must also be able to compensate for uneven weight distribution at the rear, eg a single passenger rather than two. So it probably measures the norm at the point the car starts to move.

              My point is this If the passenger then moves position while the car is in motion , or weight shifts in the boot , or even if the road has a steep camber causing it to be heavier on one side than it was originally, the system may detect this as an abnormality outside expected parameters and shut itself down. In effect its saying " I cant be sure whats going on , you humans sort it out , I have left it on level 2 " If this is the case it may be normal in certain circumstances.

              This is just a theory. I havnt researched it. Despite it being ideal weather to flop in the garden learning stuff my wife thinks its a good day to sweep the chimneys!

                I'm not sure on Corsa's, but on my Impreza it had sensors that basically changed the output voltage depending on it's position. It had one at the front and one at the back - each was fixed to the car itself and then had a rod connecting to the wishbone if I recall (it was a terrible design and let water in causing corrosion, and then was expensive to replace - I found out the hard way!). Both sensors then connected to the headlight levelling module and that worked out what level it thought the lights should be based on the voltages they each were sending.

                I assume the Corsa has a similar type of system, either that or a spirit level hiding somewhere

                  Similar to what i imagined, sensors activated by the different distances between car body and suspensions, But would I think have to be 'smart' enough to detect when the rear is more heavily loaded than normal and to average out and ignore normal suspension movement whilst driving. A single spirit level wouldnt work as it would not be able to tell the difference between a car thats tail heavy or light , and one that is simply travelling up or down hill. . (two might work - one on the suspension and one on the body, compared by computer. )

                  Sorry. If I am not thinking about stuff like this then its even more useless things such as ' why do Bulgarian flies love a roadkill badger ,but not the meat I cook on the BBQ.? (They prefer peas and rice) )
