Cracked/warped head or HG Failure
Discussion
Well the car has been in and out of the garage for water leak/temp faults for the last couple of months.
Back in again at the moment
They have tried various things.
They are struggling to actually find any sort of water leak but we seem to be constantly topping it up.
Temp gauge reads 85 one min then upto 110 the next then down to 90, basically all over the place.
They have tested the coolant for exhaust gasses and are getting a high reading (90?)
They are replacing the thermostat as saying this could be the problem...
They have briefly mentioned HG failure but dont think its this.
Also damaged head has also been briefly mentioned.
Now if its the more serious of faults...How much roughly are we looking at £££ wise?
The contingency fund is about to be used on the TVR so might have to shuffle the pennies around
Edit to add...
S2 1.8 K-series! 52 plate.

Sniffer test (exhaust gases) suggests HGF. It could, of course, be cracked head or block! (but HGF more likely on K series). Sorry mate, but your garage sounds clueless. Take to someone that knows what they're doing and won't rip you off. Where are you geographically?Back in again at the moment

The sniffer test looks for combustion by products in the water and it has found them, so there is a leak from the cylinders into the waterways. If it were gasket then the leak should be obvious on the surface of the gasket and head / block. If it isnt then suspect cracked head - which needs sending off for pressure testing. Replacement heads from a scrappie should not be difficult to find.
I sympathise with your location out in the sticks - same problem here. But there will be a garage somewhere near that is capable of more taxing work than an oil change. Alternatively try one of the specialists and trailer the car there.

Well a slight update...
Thermostat has proved to be a bugger of a job to get too, they have checked the C Head and have recommended getting it skimmed while everything is accessible.
So that's been sent away and more gaskets ordered.
Cylinder 3 is showing signs of water ingress at some point, all the other cylinders are carboned up and 3 is pretty clean.
It did have a fault code for cylinder 3 misfire, fault cleared so, again...
Back in 2009 it had HG replaced with new sort and head skimmed.
We'll see what the outcome is, not feeling overly optimistic mind.

Do they know what they're looking for?
The thermostat is undo 1 screw for the dipstick, 2 screws securing the thermostat pipe to the block and yank it out, it's only a push fit connector
Does it have an aftermarket thermostat near the rear right sill?
If it's a 111S is there an extra working water pump near gearbox?
Nice things to work on (they need TLC) but not much of a trusty work horse

worth getting the head pressure tested for leaks while its of especially if there is no obvious blow by on the gasket for that cylinder.Thermostat has proved to be a bugger of a job to get too, they have checked the C Head and have recommended getting it skimmed while everything is accessible.
