Message Hi,

I've searched but did not find anything that looks like my problem. Here it is:

Sometime the needle of the speedometer indicates a higher speed than what it is. The rpm stays the same but the speedometer needle moves up for a moment then goes down to the actual speed. I've never saw the needle going below the real speed. Also, when the needles indicates a higher speed, the odometer looks like its spinning at the same rate but this is hard to detect. Also, no warning lights turn on while the needle is behaving strangely and the steering feels the same.

I drove 400Km without any issues on the highway. but the day after, the needle moved up to 130kph then went to 120kph while I was driving at a constant speed of 100kph on the highway. The engine was revving at around 3000rpm on the fifth gear. After some time the needle stop behaving strangely then starts again.

Any help will be appreciated.
