Hi Freddy,
It takes about 4 or 5 mins to get up to temp and then sits at 90. I dont sit in hugely heavy traffic too often so cant say 100%, but i have never spotted it going above, or indeed below, 90 whatever i'm doing.
I will say however that it is pretty annoying every morning when it beeps! As i said i had it fixed before and am gonna have it done again in next couple of weeks but am starting o wonder if its gonna just come back?

It is also due cambelt change so am now wondering if maybe it could be the water impellor (as dav-aberdeen mentioned - getting worried!) but i have found NO other problems and its been doing it for a month or two!

Guess thats not entirely what you want to hear, but hope its helpful!
 
oh, and the first time it happened my dad was looking after it and called the AA who said they saw it quite a lot and cleaned it.
Might be worth seeing if the guy could just get it cleaned before you buy??
 
Ok thanks Aaron, funny you should mention yours needs a cambelt doing, as does the one im after, also the one pdcupra is after has the same trouble and the cambelt needs doing on that one too. Is it possibly a water pump/service indicator?? Hmmm...

Just spoke with the owner, hes popped some more fluid in the expansion tank and the problem seems to be solved (for now! lol)

Il let you all know how i get on
