Over heating ?
Discussion
Ok other day I was stuck at a junction for about 10 min and just as I pulled off car said warning overheating but then fell straight back down to just below half way on the temp gauge and has been fine since checked oil wasn't empty but was low so filled it up fully synthetic vaxhual 5 30 I think it was this was 2 weeks ago driven the car every day since and no problem today just went out for food and noticed temp went just over half way on a 20 min drive got concerned so checked oil and coolant both fine finished meal was stuck in tragic was half way then just jumped up all the way just where goes red and warning drove off jumped back down to just over half way no rattles or noises and fans came on does this sound like I am about to end up with a huge bill ?

Where is oil for super charger ?
Supercharger has own oil supply.You should be fine filling the radiator.
You can prob hear the inter cooler fluid, I wouldn't worry about that.
When you fill the rad take it nice and slow, make sure the water goes cleanly into the rad without splashing off the rim of the rad.
Start the car up to warm it through, put the heater to full hot, check its hot then recheck the rad level.
If the heaters not blowing hot try cycling it to cold then hot several times to get the system moving as you may have an air blockage.

Yes, the low water level was your problem, as Jez guessed. Taking the bungs out of the bonnet could change the airflow, so you might want to put them back in.
