Rough idling and limp. Help

[Iceze]

Hi

Just bought a 2012 polo 1.2 a few months ago for my niece and having trouble with it.

Using Carista, it's throwing up the following codes:
P0136 O2 sensor Bank 1 Sensor 2
P0140 O2 sensor no activity bank 1 sensor 2
P0172 System too rich bank 1
P0301 Cylinder 1 misfire
P0351 ignition coil A circuitry
11410 ignition cylin1 open circuit
11731 Fuel trim bank 1 too rich
11836 hide cylinder
06187 O2 sensor no activity bank 1 sensor 2
06350 cylinder 1 misfire
06429 O2 sensor Bank 1 sensor 2 malfuntion

Initially the car was loud a exhaust replacement sorted that. It's also had a service. This was all done soon after the car was bought.

The issue is that the car is going into limp mode randomly with the ESC light coming on. Turning off then on removes the light and limp mode clears.

The car also feels rough on idle. Our local mechanic has had a look and cleared codes but hasn't had any luck.

Or is anyone around London who can help?
