Hi I have a 2016 Mazda 6 diesel estate. In the last week I have had a few warning lights come on, traction control, city braking, dpf etc. Always go off when I restart the car, then come back on at random times. Also had a misfire today for about 5 seconds, ran really rough, felt like it was cutting out and then went back to normal. I am presuming it's some kind of electrical/ECU issue. Anyone got any ideas, and an idea on cost to repair?

Could be $10, could be $10,000.
