It sounds like they just opened the UIM and had a look because he didn't even get all the way to the lower. He couldn't find any evidence of leakage so he stopped. He said it could be leaking internally but thought that was doubtful as it would've hydro-locked by now. We thought the low coolant light was going on and off due to air but this time there was no air, so not sure now.....
I'm really hoping they bleed it well this time after opening the system up so we're not bringing it back again for an air bubble.
