my problem is my speedo only reads about halve of the actual speed im going.
ive changed the speedo itself which made no difference, i've plugged it in to my laptop where it tells me no codes reported.
however when the laptop connects to the cars ecu i get the abs system fault message briefly flash up telling me there's a problem but then disappears.
hope i've mad sense.
as far as i can see the speedo works off the abs sensors so if there was a problem wouldn't the dash have the error message displayed constantly?
has anyone had this before, if so any advice would be very much appreciated please as this is driving me up the wall lol
