A few drops of water and light vapour after a cold start are usually caused by condensation in a cold exhaust system. If thick white vapour continues after the engine warms up, coolant level drops or the engine overheats, prompt diagnostics are needed.
The temperature gauge stays below normal for a long time or the cabin heats up slowly. Check the symptoms, common cause groups and what the workshop will do during diagnostics.
After a battery replacement the car may change behaviour due to loss of adaptations and lack of battery registration. What to check before a workshop visit and when to stop driving.
Problems with starting only when the engine is warm have a few typical causes. This article helps recognise symptoms, collect useful observations and decide if you can drive to the workshop.
A practical step-by-step guide on what to check before putting a car away for a week, a month or longer. Protect fuel, battery, fluid systems, tyres, brakes, air conditioning and bodywork, plus a checklist for after storage.
Window fogging is caused by excess moisture and ineffective air drying. Learn common causes, what the workshop will check and when to stop driving.
The air conditioning gives cool air while driving, but at standstill the airflow is weak or warm. Causes range from radiator fans to refrigerant loss. What to check and when to go to the workshop.
The colour of exhaust smoke helps narrow down the causes: burning oil, burning coolant or excess fuel. The article explains what to observe and what tests a workshop will perform.
A clear increase in fuel use has many causes — from driving style and tyre pressure to sensor faults or fuel system issues. We explain what to check and what information to give the workshop before computer diagnostics.
A practical guide: from symptoms through common causes (compressor, belt, electrics, fuel, cooling) to safe checks and workshop diagnostic steps.
The radiator fan running after engine shutdown doesn't always indicate a fault. We explain when it's normal cooling and when it points to a problem with a sensor, relay, coolant or control and requires diagnostics.
If the air conditioning cools poorly, don’t assume a recharge will fix it. First rule out simple causes: wrong settings, weak airflow, a clogged cabin filter or a non‑working condenser fan. Only measurements of temperature, pressures and refrigerant amount can show whether it’s a loss, a leak or another system fault.
