Oil leak around the valve cover: is the gasket faulty?
Oil near the valve cover identifies an observation location, not necessarily the leak source.
Knowledge / Your vehicle map
Engine and oil
Start with starting issues, vibration or oil loss, then open the guide that matches your observations.
This is a topic library, not a diagnosis. Your symptom description, its conditions and your vehicle manual help you choose the right guide.
المحرك والصيانة
Engine shakes with air conditioning: is it normal?
Air conditioning adds load, but new persistent shaking needs assessment.
Suspension and tires
Suddenly heavy steering: power-steering fluid or pump?
Suddenly heavy steering does not always mean low fluid; assistance may be hydraulic or electric.

Knocking when starting a cold engine: causes
Heavy knocking at cold startup differs from light ticking.

Difficult manual gear engagement: clutch or transmission oil?
Difficult manual shifting may involve incomplete clutch disengagement, the selector mechanism or transmission internals.
Dashboard warning lights
EPC light: understand the engine power-management warning
EPC appears in some Volkswagen Group vehicles and may accompany reduced response. It does not automatically mean the throttle body needs replacement.
Cooling and air conditioning
Engine overheating: act safely, then investigate the cause
A plan for handling a temperature warning and distinguishing fluid loss, cooling failure, and an unconfirmed diagnosis.
السلامة والسفر
Before a road trip: prepare engine cooling and air conditioning without rushed checks
A practical checklist that starts with a cold vehicle and explains what you can observe and what needs a workshop appointment.
لمبات التحذير
The check-engine light is on: decide based on flashing and symptoms
What should you do when Check Engine appears, and how does reading a code differ from diagnosing the fault?
المحرك والصيانة
Engine belt squeal: what does its timing tell you?
Distinguish the belt, tensioner, and pulleys, and prepare a useful description for the technician without approaching moving parts.
السلامة والأعطال
Burning smell under the bonnet: possible sources
A burning smell from the engine bay does not identify a particular material or component; oil on a hot surface, a belt or electrics are examples requiring safe distinction.
المحرك والصيانة
High RPM at idle: causes of a high idle speed
Elevated engine speed after a cold start differs from speed remaining high after operating temperature is reached.
Turn reading into an organized next step
Save the guide, note your observations and prepare vehicle details before visiting a professional. After service, record the completed work, its cost and follow-up date.
