I purchased a 2008 Citroen C4 Grand Picasso on 29 July 2016 with a warranty. Within a week I had bought two new front tyres and windscreen wipers for the car as they were in a poor state. A few months later we took it into our local dealership with a clutch fault. We had to pay £108 for a software recalibration, which didn't work, and apparently wasn't under warranty. After a lot of arguing we were able to get the car back to where we bought it from (100 miles away) to get it fixed, which took two weeks and a new clutch was needed and claimed under the warranty. Four weeks after the return, we had another set of problems. Oil Leak, Front door creaking, tailgate boot release not working, auxiliary belt worn out and brakes in a very dangerous state according to our local dealership. The dealership I bought the car is only offering a second review for free. What are my consumer rights? Can it be returned?
