my 156 selespeed (2001, x reg) sometimes while pulling away i change to 2nd gear, in goes in to 2nd but the computer jumps to another number, 4th or 5th, i then have to click down a gear to go up a gear!!! Also sometimes when i 1st pull away it jumps to 3rd or 4th, then when i put my foot down it then jumps back to 1st and wheel spin off. i have also noticed the rev counter isn't right, doesn't move as much as it should, it normally sits around the 0 - 1??? Any ideas? i love the car, but it's now starting to get on my nerves!!!
