Hi All I bought a 2nd hand Nissan X trail on 13th January from a local dealership. On 6th February I reported to the dealer that the car was making a loud noise from under the bonnet and that the engine management light had come on. We agreed to send it to my local Nissan dealership for them to run a diagnostic check. They diagnosed the fault code as an EGR fault and said that the noise could be coming from a worn turbo. They advised replacing the turbo and intercooler. After speaking with the dealership I bought the car from, I returned the car to them to investigate and they diagnosed a worn turbo which they took over 2 weeks to replace. They acknowledged the EGR fault, but did nothing to rectify it as the engine management light had gone out. Upon receiving the car following the new turbo, the noise was still there. I reported this again only to be told its to be expected with a car of this age and mileage. Over the past 3 weeks the noise has gotten worse and the engine management light has come on again. I have had 2 garages look at the car for me in the last few days and both say that the gear box is shot and that the EGR fault is still there and the EGR valve needs replacing. I have written to the dealership rejecting the car under the Consumer Rights Act 2015, but after speaking to them this afternoon I fear that they are just going to ignore me and try to fob me off. He is all ready talking about trying again to fix it. Do I have to accept this? or is there anything I can do to force the refund?
