Renault Service center(Midrand)

I drive a Renault Sandero Stepway 2018.

I took my car in for service last month on the 1st of August, after that I have been experiencing the same problem that can't be solved by the service center.

There is warning light that comes on, when that happens the performance of the car drops, then I took it back to be checked the 1st time and they said it just needed a reset which they did and the issue seemed to be solved. then 2 weeks later the warning light came back on, I took it back to the service center and I was asked to leave for a day so they can run a proper diagnostic. later that day I was told there is a problem with the Turbo and it needs to be repaired and I would have to arrange for the car stay at the workshop for a couple of days. I reluctantly agreed as you can imagine the inconvenience of being without a car when you rely on it. We arranged for day to bring it and it was week later on a Monday. I collected the car on a Wednesday and I was given the all thumbs up. I think the peace lasted for about two weeks and it came back again, I took the car again, it was there for half a day and I think they just reset it again. This time it didn't last a week, I called the center and I explained my issue and I received the response as to what the solution will be.
