Thank you for your reply. The car is a 2009 BMW I am not sure of the model it is a small two door hatchback 2L. The car is sending out white smoke which it did previously when it was repaired so think it is the same problem and that the job wasnt completed properly but without the details on the job it isn't possible to have this confirmed. My son is going to seek advice from a solicitor in order to get the details of the work completed and by whom.
