If that turns out to be the case then please note
T-Cut's advice. He has had personal experience of doing this and reports that it's very easy to unintentionally distort the seal between the two parts of the filter housing when reassembling. Should this happen, the result is unreliable fuel pressure which could well be the reason why you have erratic running.

I disagree. The same thing happens if you have an air lock* but first ....

Don't use the fins as a reference. The correct level is between the MIN and MAX labels at the bottom of the expansion tank. If the MAX label is covered with coolant then the tank is overfilled and is likely to eject coolant. Check this as a priority.

You originally said carbon monoxide but no matter!
As I said in my last reply, your garage is making the common mistake of starting with a diagnosis then trying to make the evidence fit it. When a piece of evidence doesn't confirm their belief (the gas test and absence of white "smoke") they dismiss it. That is not the way to discover what is really wrong and repair it in a cost effective way.
By the way, is this the same Land Rover dealer referred to at the beginning of the thread?

That's what your garage should be thinking!
