Good day, I’m new here so please forgive me if I forget any important information. Just let me know and I will submit it. So now to my problem: I bought last week a Citroen C5 2.0 (140 hp) Exclusive Automatic BJ 2006 and had to notice a few small to large defects. However, this problem is most important to me to solve. —Tacho needle far below zero for the speed indicator (15-20 km/h hangs the needle after) e.g. Tacho 50 un d Tempomat set to 65, this also works correctly. To drive 50 km/h I would have to have 35 km/h on the speedometer. – so first of all I can’t say anything or how it came to it or since when it is. Anyway it was already before the purchase. Since a test drive was not possible, I didn’t know that. I Googled a bit and found a possibility that I was very interested in whether it is so easy and will work. So.. Tacho out, cable away, disk away and Na Turn it to zero. Ready. Against clockwise if I am not mistaken or wouldn’t it matter? Or just pull it off and plug it up at exactly zero? Could or would that work so easily? I hope you can help me if something is unclear please let me know. Thanks already for reading it. Greeting Nikolay
