Hello everybody i will try keep this simple ive just purchased a Renault Kadjar 2017 from a car supermarkert about 4 weeks ago seems to be running ok up until four days ago when the day after from doing a 100 mile round trip on the motorway i had the spanner light and check injection come up on the display then about four miles later the engine management light came on followed by air pollution displayed these have been intermitent in coming on and off since, after doing a quick obd scan a list of p codes came up which are:

i would appreciate any input to what could be the problem relating to check injection and air pollution warnings these warning somtimes relate to the air sensor pipe being blocked don know if this is true in this case.

Damn.
That's a lot of codes.
I think that the car supermarket should be involved in this and rectify the faults for you.
Sorry I can't help with the causes.
Good luck.

If you've only had it 4 weeks, down to the supplier to sort it out. Assuming this is diesel, it will probably be the tube to the exhaust gas pressure sensor is blocked - have a look at O'Reilly's autos on YouTube, he does LOTS of these!
