With the engine running and the aircon on low are both fans running?

Assuming there's plenty coolant and your thermostat and inline stats are ok I would look at the auxiliary coolant pump

With VCDS you can run and test the pump in output test etc and check system values for temperatures.

Just done a battery test with a computer from work and it says bad and replace
Would this have anything to do with it
