Hi, so yesterday I went to fill up and usually after I fill up my dte says 600 ish (km) but for some reason it stayed the same at roughly 60ish km dte. I was like wtf is going on so I drove a bit for a bout 30 mins or so and it slowly started going up. Should I be concerned about it? Also may be coincidence but for some reason I had a light on my dash come on saying that the brake light is burned out so I just replaced that. any ideas or should I just ignore it?

 

usually does that when you refill on a very low tank. i have had that happen multiple times.
starts really low. over mileage dte keeps increasing...
in the end reset your trip meter and in the end it will be around the usual assumed 300+ish per tank.
