✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Signs: Oil pressure warning and engine light, rattle from the lower engine, loss of power; brake servo can get weaker
Fix: Stop the engine at once; fit the revised belt and bolted tensioner, and renew the oil pump belt at every timing belt job
Signs: Coolant level drops with no visible leak, white exhaust smoke, rough running or misfire, later overheating
Fix: Pressure-test the cooling system; if there is no external leak, inspect the integrated exhaust manifold ports for cracks and replace the cylinder head
Signs: Scored or lipped discs, vibration or noise when braking, already at the first roadworthiness tests.
Fix: Replace discs and pads per axle; check that the calipers slide freely so the new set does not wear the same way.
Signs: Usually no warning; in the worst case the pedal loses its pivot and braking is reduced.
Fix: Check the VIN for the open recall; the dealer checks the bolt torque or fits an improved pedal free of charge.
Signs: No warning; the child lock can switch itself off from vibration, or on estates a rear door may open when the window is lowered.
Fix: Check the VIN for open recalls; the dealer inspects and replaces the latch spring or rear door lock free of charge.

Fix: Check the VIN for the open recall; the dealer inspects the harness, reroutes it and replaces it if damaged, free of charge.
Signs: Start-stop or Auto-Hold not available, warning messages, slow cranking or no start after the car stands for days.
Fix: Test the battery and look for a parasitic drain; fit the correct AGM/EFB battery, register it, and ask for module software updates.
Signs: Screen freezes or goes black, navigation or phone connection drops, unit restarts.
Fix: Install the latest SYNC 3 software (dealer or USB) and do a master reset before replacing any hardware.
Signs: Parking sensor fault message or constant beeping; the camera shows wrong speed limits.
Fix: Clean and test the sensors, replace a failed sensor; update software, and do not rely on the displayed limit.
Signs: No warning for the buckle; the reversing camera image may freeze, stay blank or show distorted.
Fix: Check the VIN for open recalls; the dealer replaces the buckle or updates/replaces camera parts free of charge.

Signs: Slipping, high bite point
Fix: Replace clutch kit
Signs: Delayed or harsh shifts
Fix: Fluid service, repair
