Hi I have a renault megane grand scenic 05 plate. The over day the service light came on witch I fort take it for a service so I did and when I got it back the service light was still on and also a message that kept saying check parking break. I took it back to the garage n they said I had low pressure in the breaking system then he also quoted me 1000 pound to fix the computer that controls the breaks at the back of the car, but then he gave me the car back and said he turned the service light of aswell as the parking break message. I would of fort if there was a fault it would of come back on. Do you fink they are trying to hide there mistake by saying something has gone wrong?
