Storeyman66 Posted November 5, 2022 Share Posted November 5, 2022 Good morning I have an Audi A3 1.6 TDI and it’s started blowing cold air instead of warm/hot when switched on the warm settings , any ideas for a quick fix as it’s getting a bit cold in the mornings not to have a heater Quote Link to comment Share on other sites More sharing options...
David Wise Posted November 5, 2022 Share Posted November 5, 2022 Sounds daft but have you tried the auto button and just set your temperature ifound mine was just blowing cold but it can be a bit vague,it did work for me cheers Quote Link to comment Share on other sites More sharing options...
Steve Q Posted November 5, 2022 Share Posted November 5, 2022 I'd recommend a diagnostic check to see if any fault codes flag up regarding the heater motor and controls etc. Also does the engine get up to temperature and stay constant? I ask as a failing thermostat could cause issues. Quote Link to comment Share on other sites More sharing options...
