    The wife's speedo is way out on her A3,at 30 it reads near 40 at 70 it reads 90,what's the odds it's had box replaced with wrong box?

    Anything else likely to cause it?

    On a good note it passed mot today with jus rear bulb but only replaced that other month but it is dim compared to other side so not too bad.

    Could also be the clocks have been changed or coded wrong, you can code them for 140, 160, 180 mph or km/h etc

    If it is the clocks, anyone with vag-com can sort it for you in a couple of minutes.

    There may be a member near you that can help for beer tokens.

    I had the exact same problem with my v plate 1.6 a3. Other thing on mine was the full gauge always showed more . I tried all the earth leads as i read somewhere in was a possible cause but didn't help. I just learned to live with it .

    Should be easy to tell if your gauge is out . The warning light will come on well before it should . If i mind right mine came on about quarter of a tank on the gauge

    Not sure but i think the cluster devolops a fault. There are lots of posts about tt's getting fixed because the clusters f' up and Audi admitted a fault so maybe related . I don't think vag.com or vcds can help as they can only correct by a few miles either way where as your gauges are out by a percentage ie faster you go the more they are out . Hope this makes sense and i could be totally wrong
