Fiat Linea 323
Weaknesses, engine ratings and buying advice
The Linea (Type 323) is Fiat's no-nonsense three-box saloon built on the Grande Punto platform from 2007 to 2015. It never set out to be a sports car or an image piece, but a cheap, roomy bread-and-butter vehicle with a surprisingly large boot. Anyone after a plain, honest car for lots of miles at little money is in the right place.
The diesels are the recommendation. The 199A3 1.3 MultiJet (90 hp) is the frugal penny-pincher for town and short hops, while the 198A3 1.6 MultiJet (105 hp) is the better long-distance partner with more pull. Both are economical and tough for the class. The base petrol 350A1 1.4 8V (77 hp) is simple and cheap to run but gutless; the also-available 1.4 T-Jet turbo is more fun but rarer.
Recurring themes: rust on the wheel arches, sills and fuel flap is the main issue and decides the purchase. Add failing alternators, A/C compressor and control-valve failures, a creaky budget interior and blower resistor packs that burn out.
Test drive: scour the wheel arches, sills and fuel flap thoroughly for rust and bubbling, check A/C performance, watch the alternator and charge light, run the blower through all stages and listen for interior creaks.
Market 2026: prices run from around $900 for rusty leftovers to roughly $4,900 for cared-for diesels with little corrosion. The average sits just under $3,000. Rust and A/C are the only relevant themes.
Insider pick: a dry-silled 1.6 MultiJet from a mild-climate region with working A/C. That makes the Linea an unbeatably cheap space champion.

Good ChoiceEngine Overview
The Fiat Linea 323 is available with 3 engine variants — from 77 to 105 hp.
The 90 hp variant of the 1.3 MultiJet shares all the basic weaknesses with the 75 hp version, but is more often driven hard, stressing the turbo and high-pressure pump. As the only output with a VTG turbo rather than a wastegate, it is more sensitive to oil quality and cool-down after full load. The timing chain is under the greatest thermal stress here — inspect from 120,000 km; injectors corrode into the aluminium head, glow plugs fail. Oil changes every 10,000 km are essential, not optional.
- !! Timing chain stretch and breakage from 150,000 km
The 1.3 MultiJet uses a timing chain with no fixed interval. With degraded oil or extended intervals it stretches from around 100,000–150,000 km; breakage with engine damage is possible. Replace tensioner and guides too.
Symptoms: Metallic rattle on cold start fading after warm-up; advanced wear gives persistent rattling, worst case engine stall. - !! Turbocharger: bent vanes or overboost fault from 110,000 km
The VTG turbocharger of the 90 hp version shows power loss and overboost faults (P0236, P0045) at 120,000 km. The turbo behaves temperature-dependently — no boost when cold, partially better when warm.
Symptoms: Engine warning light, no boost build-up on cold start, overboost faults in memory, power loss - !! EGR valve carboned up from 90,000 km
The EGR valve carbons up after 80,000–120,000 km of operation and is difficult to access on the 1.3 MultiJet. Cleaning is possible but requires removal of several ancillary components.
Symptoms: EGR fault in fault memory, delayed power delivery, power loss under partial load

The revised MultiJet II variant with around 105 hp brings slightly lower friction losses and Euro 5 compliance, but shares all the major weaknesses of its predecessor. Change the timing belt at 150,000 km / 5 years – at that point always replace the tensioner and water pump at the same time, as the labour cost is identical. EGR fouling is a structural issue with the reduced displacement and low exhaust temperatures: regular cleaning from 100,000 km onwards makes sense. The DPF is sensitive to short-trip use; if a vehicle has spent half its life in city traffic, the filter is often well beyond the load threshold. Engine mount failures occur roughly every 50,000–70,000 km, but are inexpensive to fix. When buying, check the oil service records – old oil gradually damages the injectors.
- !! Timing belt tensioners wear out from 120,000 km
Timing belt tensioners and idler pulleys wear out faster than the belt itself. If the timing belt breaks or jumps on this interference engine, total engine damage results.
Symptoms: Loud engine noises, engine fault after timing belt replacement if incorrectly positioned - !! Swirl flap failure in intake manifold from 120,000 km
The plastic swirl flaps in the intake manifold wear and break beyond 100,000–120,000 km. Fragments can be ingested into cylinders causing serious damage. Error codes P0660 or P2004.
Symptoms: Check engine light, power loss especially under load, rattling from intake area, occasional limp mode. - !! Glow plug seizure and breakage from 90,000 km
Glow plugs corrode into the aluminium cylinder head threads after 80,000–100,000 km. Removal attempts break them off, destroying the thread — a cylinder head replacement may follow. Replace preventively, cold, with penetrating oil.
Symptoms: Hard cold start, pre-heat light flashing, check engine light, extended cranking in winter.

Larger FIRE variant with 77 hp, shares most characteristics and weaknesses with the 1.2. Robust in character, but needs higher revs for decent power delivery. Cold start and temperature issues have been documented repeatedly. Overall reliable with consistent maintenance.
- !! Ignition coil and ECU failure from 90,000 km
Faulty ignition coils are also a known issue on the 1.4 FIRE. In severe cases, a coil failure can affect the ECU. Fault codes P0351/P0352 typically occur at operating temperature.
Symptoms: Juddering at operating temperature, engine warning light, occasional power loss, rough idle - !! Water pump leaking from 90,000 km
As with the 1.2 FIRE, the water pump of the 1.4 FIRE is considered a wear item that should be replaced at the latest during the timing belt service. Workshops report frequent leaks from 80,000 km.
Symptoms: Coolant loss, temperature rise, coolant level drops without visible leak - !! Fuel pump with pressure loss from 100,000 km
On the Grande Punto with 1.4 FIRE, fuel pumps have been documented that could no longer maintain operating pressure of 3 bar. Result: power loss, rough running and engine warning light.
Symptoms: Significant power loss, engine won't pull, engine warning light, juddering under load

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Rear Strut Mounts Worn Rear strut mounts on the Linea 323 need to be replaced regularly. They produce rattling noises and deteriorate driving stability. Symptoms: Knocking from the rear over road irregularities, unstable driving behaviour, imprecise steering from 100,000 km | Low | |
| Shock Absorbers and Suspension Rattle Creaking or rattling suspension noises indicate worn shock absorbers. Uneven tyre wear due to wheel alignment issues. Symptoms: Suspension knocking and creaking, uneven tyre wear, swaying at higher speeds from 100,000 km | Low |
