Got a faulty thermostat, seems to have a mind of its own
Does it do any damage to the engine at all ?

Better not, mine has been dead for 4 years. It will lower MPG as the ECU thinks the Engine is having to warm up.

It depends on if the thermostat is locked open or closed
In most cases it will fail locked open, this is not an issue
This results in overcooling the engine
However, if the thermostat locks closed, then it is an issue
This results in reduced cooling in the engine, and may eventually end in overheating and engine failure
The stat never goes above 85c , but like today it took over 20 miles before it moved but it only moved a little bit, later on it was 85c but then drooped down to the bottom again
Its a 1.9 cdti if that makes a difference, thought diesels only use what fuel they need and dont waste it like a petrol , could be talking waffle but that's what i was told many years ago
as gazza said,,,it may increase fuel consumption as an over cooling or stuck open thermostat will make the ecu work the engine slightly harder to get it up to operating temperature all the time,,,i drove a car once for a year with a termostat that never raised above cold,,and to be honest it never caused problems,,,they are handy to change tho mate,,and not that expensive either
It'll be jammed open. Common fault.

it took me an hour max to do my one mate,,,,,,,,theres a how to on this that u dont have to drain all the coolant from the system,,its a good guide
Change it, simple enough if it's the 150.
Mine was like you describe, it will be stuck open.
Around £35 off ebay.

Give em a ring first just to check you've got the correct one, next day delivery if ordered before 3pm
There's also an 'How to' somewhere on the forum.

Its the 120 i have , seems to have a large silver round thing above it , looks a bit tricky to get to the screws.
Thanks for the link
