Posted 23/02/11 11:20 AM Share Posted 23/02/11 11:20 AM usually for car to start in 2nd the btr would need a manualized valve body. With manual gears, can you take off in second? If its an s5 solinoid an error would pop up. Again, depends what diagnostic computer you are using. Link to comment Share on other sites More sharing options...
