What service symbol is on,the spanner icon or a warning triangle?
You can reset the spanner icon yourself.Left hand switch in 'mode',then press and hold the select button.Select 'diagnosis'.Just enter the 13432 code in the diagnosis menu.You will go to another menu and you will see 'reset service'.
If its the triangle,go into the same menu but go into 'ecu diagnostics' and find the fault codes.
