Anyone had this? Driving along at a constant speed and for no apparent reason both the speedometer and rev counter needles drop down around 1/4 of the range and then pop back to normal. Its happened twice to me now, once about a month ago and the other around 4 months ago. Both times doing a constant 70 mph on clear motorway.
Not really too concerned just curious and hoping its not a sign of impending failure of 'something'
