Fiat Grande Punto 1.3 Multijet

The 1.3 Multijet uses a lightweight timing chain with a hydraulic tensioner that is prone to wear. The tensioner bleed-back valve weakens over time, allowing oil pressure to drop overnight. Symptoms start with a rattle lasting 1-30 seconds on cold start. Failure typically occurs between 100,000-160,000 km, though neglected oil changes can accelerate this to 60,000-80,000 km. Preventive replacement of chain, tensioner, and guides costs around 500-700 euro at an independent shop. If the chain snaps or skips teeth, valve-to-piston contact destroys the head, pushing costs to 1,500-2,500 euro for head rebuild or engine replacement. Fiat has updated the tensioner part over the years. Regular oil changes every 10,000-12,000 km (rather than Fiat's 15,000 km interval) significantly reduce risk.

The EPS column is a very common failure on the Grande Punto from 2005 onwards. The torque position sensor inside the steering column degrades, initially causing intermittent heavy steering that always becomes permanent. The EPS warning light illuminates on the dashboard. A new column from a Fiat dealer costs 800-1,000 euro fitted, while specialist reconditioned units are available for 400-600 euro including fitting. Some specialists offer ECU-level repair of the torque sensor for around 200-300 euro. There was a steering column recall covering 500,000 cars built in 2008-2009 for a different issue (loose upper shaft bolt), which should be verified as completed.

DPF-equipped models (generally from 2007 onwards, though DPF was optional on some earlier variants) suffer from clogging when used predominantly for short urban trips. The engine ECU monitors oil quality and blocks regeneration cycles if it determines the oil is too degraded, accelerating DPF blockage. Fault code P2002 indicates a clogged DPF. A forced regeneration with diagnostic software costs 100-200 euro but only works if the filter is not severely blocked. Professional DPF cleaning costs 300-500 euro. Full DPF replacement with aftermarket unit runs 600-1,000 euro, while an OEM filter can reach 1,500 euro. Important: after every oil change, the oil degradation counter in the ECU must be reset using specialist software like Multiecuscan, otherwise regeneration remains blocked. Pre-DPF models (pre-2007) avoid this issue entirely.

The EGR valve on the 1.3 Multijet is difficult to access compared to the 1.9 variant, increasing labour costs for cleaning or replacement. Carbon deposits build up over time, restricting the valve and causing symptoms including rough idle, hesitation, loss of power, and black exhaust smoke. Cleaning with specialist products costs 100-200 euro at a garage. A new EGR valve costs 100-300 euro for the part plus 100-200 euro labour due to difficult access. The valve should ideally be cleaned every 50,000 km. Some owners opt for EGR blanking plates, though this is not road-legal in most European countries.

The variable geometry turbo uses an actuator that can seize from carbon deposits, particularly when the car is driven gently or only on short trips. Symptoms include EPC/check engine light, limp mode, and loss of power. The actuator alone can sometimes be freed by cleaning the vanes through the exhaust side with oven cleaner, but if internal damage has occurred, the turbo must be replaced. Turbo replacement costs approximately 800-1,500 euro at an independent garage, while Fiat dealers can quote up to 1,800 euro. Some failures have been reported as early as 40,000-50,000 km, though most occur beyond 100,000 km. Regular motorway driving helps keep the turbo vanes free.

The 90 hp version uses a dual mass flywheel that smooths out the diesel engine's injection pulses. The DMF wears over time, causing a metallic rattling noise at idle and juddering during clutch engagement. Replacement of the DMF and clutch kit together costs 600-1,000 euro at an independent garage, or up to 1,200 euro at a dealer. Conversion to a solid mass flywheel is possible for around 400-600 euro total but may increase cabin vibration. Typical failure occurs between 120,000-180,000 km.

The MAF sensor can fail or give incorrect readings, causing poor throttle response where the accelerator must be pressed 2-3 times before the engine responds. Diagnostic code P0101 may or may not be stored. A new OEM MAF sensor costs approximately 100-200 euro, plus 50-100 euro for fitting. Cleaning the sensor with brake cleaner or MAF-specific spray sometimes resolves the issue temporarily. Only diesel Grande Punto models have a MAF sensor.

The Grande Punto is prone to corrosion on the sills (where they curve up to the wheel arches), front wings, rear wheel arches, and subframe. In salt-road countries, structural rust can develop to the point of MOT/APK failure as early as 10-12 years of age. Rust typically starts from inside the sill cavity. Repairs range from 300-500 euro per sill for welding and treating, up to 1,500 euro if multiple panels need replacement. Exhaust centre silencer also rusts through after 60,000-80,000 km on short-trip cars, costing around 200-400 euro to replace.
