2018 Volt with cooler leak and engine not available error for time to time
I just replaced my EGR valve with a used one. It wasn’t blowing any fuses so now I think that wasn’t the issue.
I’m still getting problems with the engine where it will say propulsion power are not available or engine not available rather and at this point, I don’t know what the cause is.
When I hear the engine, I sometimes think it’s having a misfire and it’s shaking a little more violently although it’s not giving me a check engine light flashing but when it has this problem, I pull over and reset and delete all the codes. I don’t know if this is helping but I’ll randomly be able to drive 1000 km without issues or sometimes it’s only 50 km but it seems to be fairly random now.
The coolant for the battery is the one with the leak and I wonder if this is something to do with the issue. I keep the level topped up all the time, but it still happens.
Please tell me your thoughts.
