Lancia ypsilon 846

Development of the proven 1.3 MultiJet with stop-start system. Economical and torquey, but prone to issues with the EGR valve and dual-mass flywheel in short-trip use.

• !! DPF blockage from city driving from 70,000 km

  The DPF of the updated 1.3 MultiJet (312B1000) blocks with frequent short trips, as the regeneration temperature is not reached. Motorway driving can burn the filter clear.

  Symptoms: Limp mode, engine warning light, power loss, rising oil level from fuel dilution

• !! Turbocharger bearing failure from oil starvation from 100,000 km

  The small Garrett turbocharger on the 1.3 MultiJet is very sensitive to oil starvation and contamination. Infrequent oil changes lead to bearing damage.

  Symptoms: Turbo whistling, power loss, blue smoke, oil in the intake tract

• ! EGR valve carbon deposits from 70,000 km

  The EGR valve of the 312B1000 tends to carbon deposits. Regular cleaning or replacement is particularly important with short-trip city vehicles.

  Symptoms: Judder, power loss, fault code P0401, rough running at part load

Euro 6 variant of the 1.3 MultiJet with reduced power and optimised exhaust aftertreatment. Timing chain instead of belt on late versions, but check chain tensioner and EGR valve.

• !! DPF regeneration problems from 70,000 km

  DPF blockage is the most common problem on the newer 1.3 MultiJet generation. Short trips prevent automatic regeneration; a forced regeneration or replacement becomes necessary.

  Symptoms: DPF warning light, power loss, rising oil level, limp mode

TwinAir with natural gas drive. Low fuel costs, but limited filling station network. Service the gas pressure regulator and valves regularly.

• !! Dual-mass flywheel and clutch wear prematurely from 80,000 km

  The DMF and clutch on the TwinAir CNG wear prematurely. The more uniform combustion pressure in CNG mode only slightly changes the drivetrain load.

  Symptoms: Rumbling when pulling away, vibrations at certain rev ranges, clutch slip

• !! Ignition coil failure — recall on early production years from 30,000 km

  The twin-cylinder TwinAir is sensitive to faulty ignition coils. On early production years there was a recall involving replacement of the ignition coils and a software update. Retrofitting is also recommended outside the recall scope.

  Symptoms: Judder below 2,500 rpm, start-stop warning light, engine warning light, noticeable power loss.

• ! CNG pressure regulator and injectors wear from 100,000 km

  The pressure regulator and gas injectors in the CNG system require regular inspection. Gas leaks around the pressure regulator are rare but safety-critical.

  Symptoms: Gas smell, reduced performance in CNG mode, increased gas consumption, delayed switchover

Twin-cylinder turbo engine with electrohydraulic MultiAir valve actuation. Technically interesting but maintenance-intensive: oil changes strictly annually or every 15,000 km, as the MultiAir unit is extremely oil-sensitive. Timing chain instead of belt, but documented early chain failures are known.

• !! Timing chain jumps prematurely from 60,000 km

  Timing chain can jump a tooth as early as 38,000 km — documented case with 1,650 € repair cost (diagnosis 150 € + chain with sprockets and labour 1,500 €). Often linked to prior MultiAir unit damage.

  Symptoms: Engine warning light on, but engine may still run smoothly. Only detectable by reading fault codes from the ECU

• !! MultiAir unit failure from 80,000 km

  The electrohydraulic MultiAir valve actuation system is extremely sensitive to old or incorrect oil. Failure leads to harsh running and starting difficulties. Repair costs approx. 1,200–3,000 €; Fiat often offers goodwill.

  Symptoms: Severe judder and clattering especially on cold start, extremely rough running, engine warning light, power loss

• !! Cylinder head hairline crack and coolant loss from 80,000 km

  The TwinAir cylinder head can develop hairline cracks under thermal stress, especially on the 105 hp version. Continuous coolant loss without any visible external leak points to this problem.

  Symptoms: Dropping coolant level without visible leak, white exhaust smoke, engine overheating, coolant smell in the cabin

+ 3 more engine weaknesses + vehicle weaknesses

Factory LPG version of the FIRE 1.2. Cheap to run on LPG, proven technology. Check valve seat wear and the gas system regularly.

• !! Valve seat wear from LPG operation from 100,000 km

  LPG burns with fewer residues than petrol — the missing soot layer on the valve seats leads to increased wear and recession. Exhaust valves run hot and hammer microscopically against the seat. Gas-hardened valve seat inserts solve this permanently.

  Symptoms: Compression loss, rough idle, declining power, higher gas consumption despite unchanged driving pattern.

• ! LPG injectors fouled from 80,000 km

  The gas injectors become fouled by deposits in the LPG system. The result is uneven gas distribution and judder. Cleaning is often sufficient; in stubborn cases the injectors must be replaced.

  Symptoms: Judder on gas operation, rough idle on gas, engine runs perfectly on petrol.

• ! Crankshaft seal leaking from 100,000 km

  The rear crankshaft oil seal hardens with age and begins to leak. Oil seeps out at the engine-gearbox interface. The problem occurs equally in LPG and petrol variants.

  Symptoms: Oil spots under the vehicle, oil film on the gearbox housing, dropping oil level.

• ! Crankshaft oil seal leaking from 100,000 km

  On FIRE 1.4 16V engines, the rear crankshaft oil seal leaks: oil seeps out and contaminates the clutch area and timing belt. Typical age-related issue from around 100,000 km.

  Symptoms: Oil loss at the rear of the engine, clutch engagement deteriorates, greasy timing belt, oil smell

• ! Thermostat stuck — heating and temperature regulation disrupted from 90,000 km

  The thermostat on the FIRE 1.2 8V frequently sticks in a half-open position. The engine reaches operating temperature only slowly, and cabin heating output drops noticeably. A faulty thermostat can promote head gasket damage in the long run.

  Symptoms: Temperature gauge stays in the lower range, cabin heating weak, higher fuel consumption in winter.
