Alright all,my R has let me down today..pulled up at set of traffic lights and smoke started coming out of the drivers side under the bonnet check coolant light flashed up on dash,turned car of straight away then got out of car to find coolant coming out of the top of the coolant bottle

,when cooled down filled back up with water and checked to see if any leaks coming out there was none coming out from anywhere,so started to make my way home.Got half way home and stop light came on again,so waited till cooled down then filled back up with water and made it home without stopping again..(think my water pump has now packed up)is this an expensive fix?any advice would be much appreciated.
Thanks to andy4motion for ringing me back with what may be causing this

.....

Cheers Mick.
ps,thanks to all the people that didnt stop and ask if needed any help.not one person while i was there for an hour stopped to see if could help in any way.....

Or thermostat?

Either way I would change both

Could even be the fans not coming on.

Once the coolant to boil the valve on the coolant cap releases the pressure.

Water pump or thermostat it is then
As above you would just change both anyway.
When you do fix it make sure you drain the system and refill with the correct mix of G12++ / G13 and distilled water.

Did your temp gauge only start rising at traffic lights?

For an OEM waterpump, thermostat and labour I would estimate between £100 and £150 depending on labour rate and diagnosis time.

Thanks Andy....im no good with car stuff but would always stop to see if could help in any way,three weeks ago an old e-type jag had broken down in outside of two lanes you could see they where going to the church to get married as bride was standing on pavement and car had all ribbons on yet not one other person stopped to ask if they needed any help so helped them move their car to a car park and offered them a lift in the R to the church but they had already made other other arrangements,what is this country coming toooo!!!!!!!

First thing i see was smoke coming out from under the bonnet,then stop light then check coolant,be honest didnt look at temp as soon as saw smoke turned engine of and got out of R am sure would have noticed while driving along if temp had gone up past 90.

Sounds thermostat to me. Mine did eactly the same as yours. I paid 220inc vat and parts and coolant at vw for the thermo to be done. They replaced all the housing seals bolts etc...if you had hot air out the vents pump is probably ok.

Mine did this on the drive home from buying it! a happy day turned into a sad one

The dealer paid for it fixing so not too bad but i don't know how much it costs, they first changed the water pump but that was not the cause, it was the temperature sensor in the end

I changed the thermostat on my mk4 gti.. It's pretty easy to do, can't see the R being any different?

 

[andy4motion]

Whenever this happens to anyone.... The sequence to go through for checks, starting from easiest/cheapest to most difficult/expensive...
1. Belt
2. Cap
3. Fan fuse
4. Fans.
5. Thermostat
6. Coolant sensor.
7. Pump.
8. Head-gasket. (Worse case scenario) but this will normally be signified to plums of white smoke out the back & running like a dog!!

 

[cuprabob]

9. Porous block or head (my worst case scenario that came true)

Mine did the exact samething and it turned out to just be a split hose! Hopefully its nothing major-
