Mercedes-Benz C-Class 2015

MUST READ*** I bought this car only a month ago. There appeared to be no issues with it. Fairly clean outside bar a few bumper marks. Spotless inside bar some tearing on the driver's seat. About a week ago I got a check engine light so I brought it to a garage where they told me that the DPF and Adblue systems have been removed from the car. However the car is yet to be mapped. The alternative is putting a DPF back in the car (which is expensive). They also told me that the fly wheel is rattling which would be the next thing down the line to be fixed. Problem is that id already gone over my 5k budget to buy the car so its just not a project I want. I refuse to put it back up for what I bought it at without being transparent about its issues. Its still now running smoothly but has those 2 expensive fixes coming up so am willing to take a loss on it and just move it on to anyone who can either do those fixes themselves or willing to take on the costs. Car features: Full climate control Electronic mirrors Tinted rear windows Built in hands free Bluetooth stereo system Cruise control Steering wheel button functions Electric seats NCT until next June but engine light is currently on.
