A full diagnostic check should first be performed to eliminate all other possible causes for your symptoms, even if the symptoms match those specified on the common fault description. If you are not sure that this part is the cause of the fault then we recommend that you do not go ahead with this purchase and instead seek further professional advice and diagnosis.
