Thank you for your kind response, I am trying to get the garage I brought the car from to pay for the repairs, but they are been very differicult and say that lambda sensors are wear and tear items, so they are not liable. I only drove 270 miles before it broke down. Trading standards say that they have to pay for the repairs under the Sale Of Goods Act 1979. I also paid a deposit by credit card, so I am also covered under Section 75, they are equally liable.I will have to decide as to wether I let my local garage, continue with the repairs or wait. At the moment I have a £5000.00 car sat outside my house which I cannot drive, and needs £400.00 plus spending on it.
