Audi Repair Near Windsor, CT: No Heat at Idle

By the technicians at Precision Auto Repair · October 25, 2026 · 2 min read

Short answer: No heat at idle on an Audi can come from the cooling system, and on this one the coolant lines on top of the engine had gone brittle. We replaced them at our South Windsor shop, a quick drive for Windsor drivers, so see our European car repair in South Windsor.

The car

An Audi came into our South Windsor shop with no heat at idle. On top of the engine, the coolant lines had turned brittle with age and heat. We replaced them and fitted a new coolant line.

Why coolant lines matter

Your heater uses hot coolant from the engine. Lines and hoses go brittle over time from heat, and a weak line can crack or leak. A cooling system problem can also lead to the engine running hot, so it’s worth checking early, not just for comfort.
