R36 Overheating

[apom]

Had a strange thing happen today... was doing the general rounds between taxi courier and general do it all when i was waiting for 5 minutes in the shade with the engine running when the aircon stopped working.

So as I started moving away I look down at the temp and it is just touching 120, the light starts to flash and I get a warning to check coolant. So, i turn all the accessories off and the temp guage starts to drop as soon as there is some airflow. Stopped briefly at some lights, temp starts to rise again, move away and with 3 minutes the temp is back at normal.

It is 35 today in brissy and we have a beautiful dust storm again but this is surely not to be expected.

I have checked the fluid levels and all as should be. Anyone else had similar issues or any ideas?

Never had this problem, but I would get this checked ASAP!
This should never happen, you should be able to idle with A/C on etc. for hours...
Maybe check your fuses and see if a Fan Fuse has blown.
Or even just lift the bonnet and see if the fans are engaging.

Yep I'd be checking the radiator fans. They have to run when the air con is on and that is the easiest way to check if they're working. Start the car up with the air con off and then turn the air con on. You should hear/feel the difference once they kick in. I'd open the bonnet and have a look too.
Cheers,
Trent

Ok, spoke to the 1800 support and as the temp light has flashed it needs to go back to dealer. I just checked the fuses and without pulling out each one they seem to be ok. The book is friggin hopeless and doesn't tell you what ALL the fuses locations are. I have fused not listed in the book and other that you would think have a fuse are just blank. To make it worse the diagram for the in car box is for a LHD and mirror reversed.

When i start the car now after about 5 mins the air con cuts off, there are no additional fans cutting in, so i suspect that could be the problem. The temp did not seem to rise however.

One question also please. When I was checking the fuses I had a call during a fuse check and need to double check the location of a fuse please. If you have an R36 can you tell me if you have 25AMP fuse in your slot F11 or F12 please in the under bonnet fuse box. Much appreciated! The book doesnt show it!!

Get it to your VW dealer as soon as possible. It's not worth trying to diagnose it over the internet.

We had a customer who drove her TDI Tiguan to the point where it shut down completely, after it overheated. VW were extremely reluctant to replace the engine under those particular circumstances.

yep, its not going anywhere buy itself, already have the tilt tray organised for 7am Monday. Thought I would just check the simple things or known issues with others

No R36, however when I refer to page 80 (booklet 3.3) I have the High Fuse Box. I have a 25amp fuse (yellow) in Slot F11, nothing in slot F12.
The booklet gives no reference to what Slot F11 is.
But if you have a Low Fuse Box, then F12 is for Telephone.
