1. EGR (Exhaust Gas Recirculation) problems

Symptoms: loss of power, smoke, exhaust system error.

Cause: carbon build-up in the EGR valve or clogged cooler.

Solution: regular cleaning or replacement of the valve and cooler.

2. Clogged Diesel Particulate Filter (DPF)

Symptoms: loss of power, frequent regenerations, DPF indicator on the dashboard.

Cause: ineffective regeneration, short trips or injection system faults.

Solution: forced regeneration, filter cleaning or replacement.

3. SCR (AdBlue) system faults

Symptoms: power reduction warning, emissions control system errors.

Cause: problems with the AdBlue pump, injection nozzle or NOx sensors.

Solution: diagnostics and replacement of faulty components, use of high-quality AdBlue.

4. Oil or coolant leak

Symptoms: low oil/coolant level, traces of leaks.

Cause: wear of seals, gaskets, cracks in the housing.

Solution: localize the leak, replace gaskets or damaged parts.

5. Turbocharger wear

Symptoms: whistling/noise of the turbine, loss of power, increased oil consumption.

Cause: ingress of contaminants, insufficient lubrication, prolonged operation at high speeds.

Solution: replace the turbine, check the lubrication system.

6. Problems with the fuel injection system

Symptoms: unstable engine operation, smoke, difficult starting.

Cause: wear of injectors, fuel pump, fuel contamination.

Solution: diagnostics, cleaning or replacement of injectors and pump.

7. Wear of camshafts and rockers

Symptoms: knocking in the upper part of the engine, loss of power.

Reason: lack of lubrication, natural wear.

Solution: check the condition of the shafts, replace if necessary.

• Use high-quality fuel and oils, strictly according to Volvo tolerances.
• Perform regular maintenance (MOT) in accordance with the regulations.
• Do not postpone the elimination of errors on the panel - they may indicate hidden faults.
• Keep the cooling system clean and change the antifreeze in time.
