Ok recentley my 2003 BA xr6 turbo has been going into to limp mode frequentley, we put it on a scanner and it came up with s5 solenoid error code. It was getting so bad that just hitting a bump or even driving along a highway it would go into limp mode, we are currently taking the s5 out and will replace it, does anybody have any other ideas on what it could be , certain local mechanics don't seem to know the answer.
