Engine light flashes and shakes car when turned on.

OBD2 showing the following codes
2AF4
2AF2
2AF6
29CD
29D9
30EA
2AF0
A559

Any advice on what the underlining issue could be linked to the symptoms and codes?

Thanks

These are misfire, oxygen sensor, low fuel, high nox gases etc., did this happen all at once? If so, we need to start with a compression test to see if the engine is in good shape, check cylinder #1 first. Here is a guide to help you. please report back with your findings. You can rent a compression gauge from an auto parts store for cheap or free.

Let us know what happens and please upload pictures or videos of the problem.

I got the car with these problems a week ago. Its last MOT was fine with no mention of the issues stated. I will try to check cylinder #1 within the week and show some more information. Thanks
