On some DC13 modifications, problems with camshafts (cam wear) and timing chain tensioners (especially when maintenance intervals are violated) were observed.

Errors on the CAN bus between the ECM and other units during power failures.

🔧 1. Problems with the EGR system (exhaust gas recirculation)

EGR valve coking

Breach of the EGR cooler tightness

Loss of traction, errors on the panel (e.g. SPN 412, FMI 3)

🔧 2. Malfunctions of the SCR (AdBlue) system

AdBlue crystallization in the dispenser and tubes

Errors in the dosing system (NOx sensor, urea pressure)

Problems with starting in winter

🔧 3. Wear of the intake manifold and flaps

Malfunction of the intake flaps (difficult starting, unstable idling)

Mechanical wear or failure of the drive

🔧 4. Leaks and cracks in the intercooler or pipes

Decreased boost

Increased fuel consumption

The turbine goes into emergency mode

🔧 5. Injector and PDE (pump-nozzle) malfunctions

Fuel leak into oil

Misfires

Difficult hot starting

🔧 6. Severe contamination of the fuel system

Clogged filters, especially with low-quality diesel

Drop in pressure in the rail, fuel pressure error

🔧 7. Engine overheating / cooling system malfunctions

Fan viscous coupling malfunction

Radiator blockage from the inside or outside

Coolant leak from the water pump gasket

🔧 8. Oil leaks

From the valve cover gasket

From the front crankshaft oil seal

Around the turbocharger
