WHy not just take it back to where you bought it from and get them to check the code?
The dealership wont just take your word for whats wrong.
If you want the fault repaired under warranty, if it is warrantable, then the selling dealer has to carry out the diagnosis and confirm the fault anyway.
You may be able to take it to an AHG Suby dealership and get them to carry out the diagnosis.
You should contact the selling dealer and see what they say
