1.2TSi Turbo Cooling

[Fatbloke]

The other day after a spirited drive (but not ragging it) I opened the bonnet and could hear a gentle hum and trickling water. On closer inspection the water was coming from the return hose into top of the coolant reservoir. It appears that there must be a pump in the coolant system to continue cooling the turbo after you have stopped. It ran for about 5 minutes before stopping. This is quite encouraging to know you probably don't have to worry too much about the residual heat in the turbo when you stop.

Thanks for the info my mate asked if the 1.2tsi has this feature and I wasn't sure he's been letting his cool down.

yes its an auxiliary water pump and continues to run if the car is over a certain temperature most new vag models have them if they have a turbo
