I recently wrote to you about a buying experience at a large car showroom when my sister bought a 2003/03 BMW 320d SE. I recommended she get her local garage, which has looked after her decently in the past with her former 318i, to change the oil and filter and possibly the pollen filter, and to give the new car a general check using their computerised analytical equipment. The only fault to come up was a non-operating cooling fan - the garage puts it down to a u/s module, and says the fan must be replaced. My sister told me that on the only long journey she has done so far the coolant temperature gauge did not rise above the mid-point, though she said the car did get hot inside. I do not doubt the integrity of her local garage. The cost to replace the fan is £381, including labour and VAT. The dealer refutes liability, but has said he will make a goodwill contribution of half. The car came with a 3-month warranty - and I believe that under the new Sale of Goods Act, the car can be returned if not fully satisfactory or the supplier will not pay for any defects to be rectified. She would like to keep the car. Could you advise me on her position, please? Should the cooling fan be covered under the warranty?
