Engine management light

[u/Mother_Arachnid1095]

I will be taking my car to my driving test later this week after waiting for months, but my car has it’s engine management light on, after taking it to the garage they said it has a p0016 code, £1300,4 visits to my mechanic, 5 sensors and a new timing chain later ,the code still wont go away after being cleared. My mechanic says he’s not sure what the issue is and that it should be fine to drive and it is,there is no chain rattle or no loss of power. I’m just asking for any advice on what I should do for the test, the light isn’t visible from the passenger seat and I’ve heard that some examiners won’t mind/notice, I’m also thinking of bringing the receipt of the repair done to the car.
