Water temp light..normal?

[rubjonny]

check the level when the light comes on, it may be dropping due to pressure building up in the tank?

Thanks, I wil try that.....however I dont want to open the coolant tank cap at these temperatures?
(My tank plastic casing is kinda dull and cant see the levels from there)

Thanks for all your comments 

[rubjonny]

no definitly not!  shake the car, that sometimes allows you to see the levels when you see the slightly murkier water sloshing about in the murky tank 

[Goops]

  Sounds like a practical solution will try this at some point tommorow!
Say I did notice a level drop due to pressure build up in tank....what would be the way of releasing this?
Refill, let engine run and wait to boil over then cap back on?

Thanks!

[rubjonny]

nah just top it up a wee bit more, also id replace the tank cap in case its venting too soon/late

[Goops]

Thanks Il top up tonight! I did actually get a new cap from VW last month..touch wood it didnt come on today so will find out on the way back from work today!

coolio
could just be the tank sensor is covered in crud so not working well, if you cant see thru the tank then a good chance this is so!  New one isnt too much

Normal oil running temp is safe up to something like 140 on the MFA according to the handbook. Valvers run hotter too. 

is that right!
mine went to about 116 once and i nearly shat myself as it normally never goes above 102 - 104.

Yup, it said it in my handbook on my old 8v cabby. I've seen my old 8v cabby up to 116 while tanking down the M1 and that was ok. I hold my camper off when it gets to an oil temp of about 120 so you should be ok in yours. 116 should be ok but if it starts getting to 120+ then I'd personally slow down.

it was in the middle of Buxton on a Saturday afternoon this summer.
I just pulled over and let it cool down.
My car was new then and i was a bit paranoid i guess.
