Wow. You have dodged a bullet on that car, particularly buing it from BCA.
Lesson number 2; dont buy 4 cylinder petrol BMW's. You are lucky to not have problems with chain, injectors, valve seals or all of the above!
Newly serviced, New MOT and no faults showing on the diagnostics befor the sale.
I did tell him of the faults and told him to come after I had serviced it and fixed it up he was so keen. But I thanks for the advise
In my ads I always list any major work I have done like new clutch etc, as customer knows getting car with new parts etc and work has been carried out
He just wants a refund so will be dropping the car off Sunday
