Check engine light on

[AZRoverLR4wm]

Yes, the check engine light is actually on full-time. Not a lot of coolant spilled on any connectors if any.. After everything was put back together it actually ran OK for a while before the check engine light came on. So it actually did work for a little bit before the check engine light came on.
I’m confused. How can the check engine light come on when there are no relevant faults being registered in current faults.. is this common? How would you even know where to start in this scenario..?

GAP tool may be sending you on a wild goose chase.

My understanding is that the gap tool is the best diagnostic tool available. I wonder how much better the LR dealers tool is. Gap says no fault but the Check Engine light is on. Frustrating. Any tips on how to clear it if it is just latched? Gap tool doesn’t clear it, but then again, it shows no faults..

The factory tool is much better.
The DTCs you listed would trigger a different warning light.

The GAP tool was built by reverse-engineering code from the factory tool. Everyone loves it, but it is what it is.

Time for the electrical tape fix.

Hah! What’s that, put electrical tape over the light?
Seriously, if I put fuel system cleaner in the gas and just drove it with the light on, any issues with doing that? Is that a smart/ accepted practice?

Honestly I'd probably let the dealership plug it in and scan.

Your battery in good shape? When I would work on mine, sometimes the battery would get low and throw these types of faults initially. After running it for a little while, the faults would eventually clear.

An orange warning is nothing. If it flashes red then you need to pay attention. I bet half the Land Rover products tooling around have an orange warning light on.
