Hi Everyone,

My car is A6 2005 4F model 3.2 FSI quattro. I wonder if anybody had this problem before??And what is the solution. My car started by having a "crazy" speed reading, and it would not cam back to 0, sometimes just stop randomly in 100 or more, when the car was stop, than it was good for some time, and bad again, it went like this for some time, now it just wont work, all the other parts of the cluster are working fine, just the speed indicator wont go, is like dead in 0 sometimes it moves a litle with no sense, it goes up to 20 in a jump to come back down to 0 in another jump. also sometimes the word DEF appears in the parcial odometer!!!All lights wont go out until I drive some milles, than it get back to normal, excepet for the speed indicator!!! Can anybody help me??

Kind regards
