Hi,
I'm having problems with my Audi A3 1.6 Sport 1998 model overheating when in traffic or when idle and need some help. engine code is AKL.
I have replaced the temperature sendor and the thermostat but the fault remains.
This only seems to happen when it is warm (even when not very hot weather but sunny in the morning on my way to work) out and I get stuck in traffic for say 10mins or so. The temperature reading on the dash goes over 90 degrees and then keeps going unless I pull over and turn the engine off or get the car up to speed and air flows through the car to cool it down.
The fans do not come on when this is happening but they both work as when I put the AC on just to test the fans they both come on for about 30 seconds but then turn off. I do not use the AC otherwise as I know this will increase temperature.
If the fans are working why do they not come on when the car is clearly getting too hot?
Obviously once the temperature reaches 100 ish then the coolant boils and comes out of the car in the form of steam.
I have been topping up the coolant when this happens.
I can see where the steam is coming out of but this would be a symptom of the problem rather than the cause wouldnt it?- The steam would find the weakest point of the pipe network and come out of that when the temp/pressure goes up over 100.
The coolant is coming out between the engine block and water flange on the right hand side of the engine when it boils. I will be replacing the water flange p/n [FONT='Times New Roman','serif']06A121133D as it has clearly been damaged due to overheating and steam coming out of it but I still think the car will overheat after this.[/FONT]
The car works ok when driving at speed
I have read other posts about things like head gasket and the water pump but this does seem to working although I cannot check the pressure as I have no Vagcom
Any suggestions would be helpfull and if anyone has vagcom that I can connect my car to in Ashford Surrey area that would be amazing
Cheers
