I was told that my car needed a new oxygen sensor (a small diagnostic machine advised this was the fault causing my engine management light to come on). I took my car to the garage and asked if once the oxygen sensor was replaced the light would go off and all would be fine and was told he would double check everything (including the catalytic convertor). He rang me to say everything else looked fine and proceded to replace the oxygen sensor - cost £126 which I was delighted with.
However, two days later the light came back on again. I called the garage who told me this is the problem with an intermittant fault but to bring it back and he will just have a look at the wiring.
So, if I went to the dentist to have a certain tooth removed and they took the wrong one out, would I still expect to be charged?
Can someone please explain how this all works as it's a very costly business. I may as well have taken my £126 and thrown it down the drain. Yes I have a new oxygen sensor, but there was nothing wrong with the old one and apparently garages don't have to give full refunds!!!!
