Guessing Games on Repairs of my Vehicle

<p>I have a Nissan Micra wich was taken to Nissan Edenvale and they had to do repairs on the vehicle wich was making the car cut out. I was advised by a service consultant that the problem was related to the camshaft sensor. We then paid and replaced the sensor. Low and behold the first problem was fixed but the car still did not run right and kept cutting out. We took it back and asked them to assess the problem and report why it is still running and cutting out. They advised that we had to replace the fuel pump and the ignition as that was what caused the problem so we again paid for it and we got the car back. (Still the same problem occured) we then took it back and requested them to Check it again and they quoted us again on another part. So I told my girl to wait and I will take it for a second oppinion. The Repair shop I took it to told me the part that was registering as Faulty is not the part that I was quoted and they quoted me on a intake Valve solonoid but the Diagnostics said that the Crankshaft sensor was Faulty. I went to the same dealership and purchased the original part from them and had it fitted and drove the car home the engin Light came on again and I went back to the repair shop and they advised that the Car is reading the very first Part I replaced at Nissan as Faulty. This is where I am currently sitting and awaiting a warranty replacement. The Dealership can not find the real problem and they cannot tell me why the car isn't running correctly. They are supposed to be the specialists on these vehicles but cannot do their Jobs correctly. They are playing guessing games on what is wrong and I must pay for that game.</p>
