ok ive put this out many times,seems the dealers dont tell most the time,frist you need to check the battery cable ,all fusess,relays,they vibrate loose if they do limp mode,you also need to know tuching the brake even lightle will put you in limp mode.i check mine every 500 miles and yes ive found loose relays and battery loose.if you go into limp mode you can take out the key and waite for 5 t0 10 minets and it will reset.i dont know much but what ive said here i got from this form,and ive had no bad things go wrong with my spyder,so a little mantince on your part could keep you from ever seeing limp mod i hope i may have helped some one so ride like the wind and have fun.
