i had the three beeps and red light with the failed coolant temp sensor (i did scrape the 'prongs' for good measure though)

Feel... top info! seem to me that my problem is the bottle and that sensor thingy!
the coolant beeping not something I need to worry about till the winter but I'll give that screw driver thing a go later on. Will have to see if the parts garage is open tomorrow.Cupra_UK am I right in thinking I need to ask for the O-ring as well as the sensor?
What Feel is suggesting is the problem and what I’m changing are different things. But if you order the part from Seat/ VW/ Audi ask them if the O-ring is included. I bought a genuine part from elsewhere and it didn't come with the O-ring. They're only £1 from Seat but you could probably use your old one.
When I drain the coolant I’ll have a good look at what the prongs in the expansion bottle look like. Will give them a clean too if needed.

I had a look at the prong before but despite the size of the bottle there not much of a hole. Would be interested to know whats going on.
Might have a poke about with VAG-COM later see what I can find. dam thing just want it to play nice! Hope all your bits go well though mate. Will go get that sensor tomorrow if I can be nice to get this one solved!
Last quick Q: what does the G61 and G62 refer to? - ignore just been answered

It's ok, I lost about 95% of it yesterday and plan to do the flush & Change this evening so bought two 1.5l bottles.
Fingers crossed!!
Ah, okay G61 etc was all from memory...
If you do your coolant sensor when the car is cold, I don't think you'll loose any - I didn't.
From memory, O ring and C clip are different parts - I would make sure you get them, C clip is easy to break/loose.

Ok just been out with the camera to have a look.
the coolant bottle prongs look ok to me:
And I assume this is the sensor thing? Mine already green, I found it on the passenger side just underneath the smaller plastic engine cover.
Doesn't look like too much hassle but see what you mean about the C clip thing looks flimsy.

Why's that m8?
we have two possible explanations for the temp gauge hanging at 70, 80 odd
feel says a sensor in the thermostat housing, others the blk/grn top sender in the coolant pipe...
which is it?
or are both things the same?

Red lights and you seem to be connected
steady now, you do want to make 5000 posts dont you
I would remove the clip and check out the actual sensor. Mine looked green too but it was the sealent.

Nope they ARE different., and the one that is the gauge sender IS IN THE thermostat housing on the 1.8T
As far I'm concerned it's the one shown in the lower pic Petay Pan uploaded.
Mines in a slightly different location as mines a 16 valver and a lot more difficult to get at..
That's wot I'm replacing as soon as I can get one.
The one in the lower pic is the coolant temperature sender. Maybe it's different on a valver, but on a 1.8T this does NOT control the temperature gauge.

Yes Sir. No Sir. Sorry Sir.

I have the problem with the erratic temperature gauge, sometimes it sits at 0 then shoots up to 90, other times it floats around other temperatures, but doesn't overheat, so i'm guessing my issue is with the gauge sender in the thermostat housing as you suggest.
My question is, how hard is it to replace this? Is there a guide anywhere? I've seen how to replace the coolant temp sensor as pictured above, as i thought this was the issue, but i get the impression i should be changing the sensor in the thermostat housing?
Feel, I've looked at all of the diagrams for Leon engines and they all have the coolant temperature gauge sensor (G2) in the same unit as the coolant temperature sender (G62). The VR5 and VR6 engines have this composite sender screwed into the thermostat housing, but all the 1.8t engines (APP, AJQ, ARY, AYQ) have the unit screwed into the coolant manifold attached to the cylinder head.
Now, it won't be the first time that the drawings are wrong, so can you tell me which engine you have and what makes you think that the temperature gauge sender is in the thermostat housing?
One easy way to tell if the unit you are looking at (green or black) contains one or two sensors is to count the number of wires going in to the connector. If it's more than two (could be three or four) then you have two sensors in the block.
