Exactly 1week ago my Engine light came in. I drove for approx. 30 minutes then parked briefly. When I returned and restarted the car it was no longer on. This happened a day after a snow storm in NY.
Today it reappeared. Definitely not the gas cap. It’s a 2017 Cooper Hardtop.
I have 36,000 miles on the car.
Any ideas / common issues? I know I’m going to have to bring it in but just wondering if any of you have had a similar problem.
Thanks,
Joseph

 

90% of the time it is an emissions issue and nothing fatal to the car .... I say 90% cuz every year makers add things to the On Board Diagnostic (OBD) system so there is 'potential'

most decent auto part stores will hook up a code reader and tell you what the system is saying the problem is .... don't be surprised if this makes NO sense to you! Common issues as you note are as simple as a loose gas cap (or one that does not seal properly). Another common and not fatal problem is a bad oxygen sensor. These sensors are what measures the gas in your exhaust for being in pollution limits ... they are in the exhaust system. It CAN HAPPEN that they get WET from driving in snow or deeper rain water and 'toss a code' .... then when weather improves, they dry out (electric connections) and all is happy (check engine goes off) ...... OTOH the sensor can be flakey and on the way to failure.

Personally I drove a car with a sensor that did not like high humidity and came on A LOT cuz I was living in San Fran' ... but was in a PITA location to replace (would cost $$) so KNOWING what was happening I just lived with it. A couple of years later I moved to a dryer area and the light/code stopped popping up
