Lancia Delta 844
Weaknesses, engine ratings and buying advice
The Lancia Delta 844, built from 2008 to 2014, was the ambitious attempt to bring the legendary name from the rally-mad eighties into the present, this time not as a sharp Integrale but as a comfort-focused compact with generous space, a long wheelbase and idiosyncratic, elegantly flowing styling. Based on the Fiat Bravo, the Delta aimed at upmarket touring comfort rather than sportiness. Anyone expecting a modern heir to the rally Delta is mistaken; this is a refined hatchback tourer with chauffeur-grade rear legroom.
The engine range is broad and interesting. The petrols run from the 1.4 T-Jet (88 and 110 kW) through the MultiAir 1.4 (103 kW) to the strong 1.8 Di T-Jet with 147 kW and around 200 hp, technically related to the sporty Alfa unit and bringing genuine sporting character. All the turbo petrols tend towards intake-valve coking; on the belt-driven 1.4 T-Jet the timing belt is often neglected, and oil-separator faults drive up oil consumption. The strong 1.8 needs attention to crankcase ventilation and turbo oil supply, and its clutch is quickly overwhelmed by high torque. The heart of the range is the MultiJet diesels: the 1.6 (77-88 kW) is a cultivated, frugal daily diesel, the 2.0 (120/121 kW) delivers solid pull, and the two-stage 1.9 Biturbo with 140 kW and around 190 hp is the most powerful compression-ignition unit in the line. All the diesels share the usual issues: EGR coking, DPF clogging on short trips and injector wear at high mileage.
The defining vehicle-level weakness is the M32 manual gearbox, whose bearings are prone to failure, an expensive and well-known problem of this gearbox generation. Add to that a knocking steering rack, faulty climate-control actuators, blocked sunroof drains, wearing wheel bearings, seized rear brake calipers, rust on bolts and panel seams after just two years, and front-axle spring breakage.
When buying used, the M32 gearbox check comes first: listen for grinding or whining in the middle gears and ask about the transmission-oil history. On the turbo petrols check oil consumption and belt history; on the diesels check the short-trip profile and DPF status. Sunroof drains, springs and brake calipers belong on the list too.
The verdict: the Delta 844 is a distinctive, comfortable and underrated compact with a decent engine choice, the MultiJet diesels in particular convincing. The M32 gearbox and the rust and electrical issues, however, noticeably dent the picture. A well-kept example with documented history is a characterful tourer at a small price; a neglected one quickly becomes a project.

Good ChoiceEngine Overview
The Lancia Delta 844 is available with 9 engine variants — from 105 to 200 hp. 2 variants had engine changes — the model year is crucial.
A modern 1.6-litre MultiJet of around 115 hp with belt drive. Economical, refined and noticeably strong through the midrange for a compact car. The usual diesel themes apply: the EGR valve collects soot deposits that hurt throttle response, the particulate filter clogs under pure short-trip use, and the injectors wear at very high mileage, showing up as hard starting or power loss. Keep to the belt interval and let the car stretch its legs occasionally. Read out the DPF loading before buying.
- !! DPF blockage from short-trip driving from 80,000 km
The DPF on the 1.6 MultiJet clogs in short-trip use. Regeneration temperature is often not reached on trips under 20 km, causing soot accumulation.
Symptoms: Check engine light, power loss, fuel dilution into oil, elevated oil level - !! Injector wear at high mileage from 150,000 km
The common rail injectors on the 1.6 MultiJet wear out from 150,000 km. Leaking injectors cause rough running and higher fuel consumption. Recoding required on replacement.
Symptoms: Rough idle, increased fuel consumption, exhaust smoke, difficult warm starts - ! EGR valve soot deposits from 80,000 km
The EGR valve on the 1.6 MultiJet 955A4000 sticks due to soot deposits and causes fault codes and power loss. Cleaning every 60,000 km is essential for city use.
Symptoms: Fault code P0401, hesitation at partial load, power loss, rough idle at low revs
The 1.6-litre MultiJet common-rail diesel is a well-balanced compression-ignition unit with a good power-to-economy ratio and strong mid-range pull. The timing belt is due at roughly 120,000 km and must not be overlooked. Weak points over its life are wearing and leaking injectors, an EGR valve that clogs with soot and carbon, and a diesel particulate filter that does not regenerate cleanly on pure short trips and can block up. For high-mileage drivers with a motorway share it is a solid, economical engine; pure city use should be avoided. When buying, check DPF condition, injector values and the EGR.
- !! Injector wear and leakage from 150,000 km
The high-pressure injectors on the 2.0 MultiJet 198A2000 can leak and cause rough running. Individual injector replacement around €250; recoding always required.
Symptoms: Hesitation, increased fuel consumption, black exhaust smoke, rough running, difficult warm starts - !! DPF blockage from 80,000 km
The DPF on the 2.0 MultiJet clogs during frequent city use and short trips. Regeneration requires motorway driving; without it, soot accumulates until blockage.
Symptoms: Check engine light, power loss, elevated oil level, limp mode - ! EGR valve carbon deposits from 80,000 km
The EGR valve on the 2.0 MultiJet clogs with carbon. Cleaning every 60,000–80,000 km recommended. Engine tuning shops frequently offer EGR delete options.
Symptoms: Hesitation, EGR fault code, rough idle, increased emissions
Slightly de-rated MultiJet variant of around 1.6 litres to Euro 5. A dependable everyday diesel with good mid-range pull and moderate consumption. Its typical faults are those of any modern diesel: the EGR valve gums up with soot and oil, causing power loss and limp mode. On mostly short trips the particulate filter clogs because regeneration never completes. The boost control valve can also fail. Regular motorway runs and clean oil changes keep this engine healthy long-term.
- !! DPF blockage from short-trip driving from 80,000 km
The DPF on the Delta 844 1.6 MultiJet blocks during frequent short trips as regeneration fails to occur without sufficient temperature. Typical for city use of the Lancia Delta.
Symptoms: DPF warning light, power loss, oil level rise from fuel dilution, limp mode - ! EGR valve seized with carbon from 80,000 km
Typical issue with the 1.6 MultiJet Lancia Delta: the EGR valve seizes due to carbon deposits and triggers fault codes. The problem occurs earlier in city use.
Symptoms: Hesitation at mid-range load, fault code P0401, power loss, rough idle - ! Boost control valve faulty from 100,000 km
The boost control valve (bypass valve) of the 1.6 MultiJet Delta can wear out or stick. Low boost pressure results in noticeable power loss.
Symptoms: Significant power drop, poor throttle response, engine hesitation under load
A twin-stage turbocharged 1.9-litre common-rail diesel with around 190 hp, the strongest compression-ignition unit in its family. Two sequential turbochargers deliver a broad, muscular torque band from low revs. The complex charging system, however, raises repair risk and cost noticeably. Typical issues are a soot-glued EGR valve, a wearing high-pressure pump with expensive knock-on damage, and a particulate filter that clogs under short-trip use. Only advisable to buy used with proven long-distance use and a complete maintenance history.
- !! High-pressure pump wear from 180,000 km
The common rail high-pressure pump on the 2.0 MultiJet 844A1000 can develop pressure loss at higher mileage due to wear. Contaminated fuel significantly accelerates failure.
Symptoms: Starting difficulties, power loss, increased fuel consumption, rough running - !! DPF regeneration failure from 80,000 km
The DPF clogs in short-trip use as the 2.0 MultiJet does not get sufficient motorway runs to regenerate. Particularly critical in city use.
Symptoms: DPF warning light, power loss, rising oil level, limp mode when severely blocked - ! EGR valve soot fouling from 80,000 km
Typical large-diesel issue on the 2.0 MultiJet: the EGR valve sticks and needs regular cleaning. Short-trip driving promotes deposits heavily.
Symptoms: Hesitation, fault codes, power loss at partial load, rough idle
Punchy 2.0 common-rail diesel with 16 valves and turbocharging, strong torque from low revs. A fundamentally sound compression-ignition engine, but it carries the usual big-diesel ailments. The turbocharger suffers under heat load if it isn't allowed to idle down briefly after hard running. In short-trip use the particulate filter clogs because regeneration never completes, and the EGR valve cokes up. The water pump also tends to fail early — replace it together with the timing belt. Great for long-haul work, but not the engine for pure city commuting.
- !! Turbocharger damage from heat stress from 120,000 km
The turbocharger of the 2.0 MultiJet is exposed to sustained high temperatures due to the close exhaust routing. Turbo damage has occurred after just a few tens of thousands of kilometres, identifiable by whistling and power loss.
Symptoms: Whistling or howling under load changes, power loss at higher revs, blue exhaust clouds. - !! Premature water pump failure from 100,000 km
Premature water pump failures have been documented on several Delta 844 examples with the 2.0 MultiJet. The repair requires extensive disassembly. At the same time, plastic intake tract components can become brittle.
Symptoms: Rising coolant temperature, coolant loss without visible leakage, squealing noise from the engine bay, overheating warning. - !! DPF blockage with short-trip driving from 100,000 km
The diesel particulate filter cannot regenerate itself when predominantly used in city or short-trip conditions. Soot accumulation leads to increased fuel consumption, power reduction and limp mode.
Symptoms: DPF warning light, noticeably increased fuel consumption, power loss especially from mid-range revs, limp mode when fully blocked.

Turbocharged four-cylinder with the electrohydraulic MultiAir valve control that uses oil pressure instead of an intake camshaft to open the valves. Efficient with solid mid-range torque, but the MultiAir module is oil-quality-sensitive and maintenance-intensive. Because it runs direct injection, the intake ports coke up over time from oil mist out of the crankcase breather, which is why the oil separator likes to fail. The thermostat also fails more often than average. Use only the approved oil grade and short change intervals — that alone decides durability here.
- !! Intake port carbon build-up from oil mist from 80,000 km
The MultiAir technology is sensitive to deposits in the intake port. Oil mist from crankcase ventilation deposits as carbon and impairs valve actuation.
Symptoms: Power loss, rough running, engine warning light, rough cold start - !! Thermostat failure from 100,000 km
The thermostat of the 198A7000 can stick open or closed. If it sticks closed, engine overheating with severe consequential damage is imminent.
Symptoms: Engine runs too hot (sticks closed) or warms up too slowly (sticks open), higher consumption - ! Oil separator faulty from 80,000 km
The oil separator in the crankcase ventilation of the MultiAir engine wears and allows oil to enter the intake tract. Oil reaches the turbo and can cause bearing failure there.
Symptoms: Elevated oil consumption, blue exhaust, oil in the air filter housing, turbo whistling
Powerful 1.4L turbopetrol with timing belt (change at 120,000 km, approx. 360–590 €). Rated as robust compared to other turbo engines when oil changes and turbo cool-down are observed. Crankcase ventilation and oil consumption through valve stem seals are the typical wear points.
- !! Timing belt change frequently neglected from 120,000 km
Mandatory timing belt change at 120,000 km costs 360–590 € (including water pump). Missing this risks engine damage. The engine mount must be removed for the belt change — complex and error-prone.
Symptoms: No warning when correctly maintained. Missed change leads to sudden engine failure or engine damage - !! Turbocharger damage from oil coking from 180,000 km
Turbocharger damage at high mileage (220,000+ km) or after short-trip operation due to oil coking in the fine oil passages. Classic cause: engine switched off immediately after hard driving without a cool-down phase.
Symptoms: Power loss, whistling from the turbo, limp mode above 3,500 rpm, blue exhaust smoke - ! Oil consumption due to valve stem seals from 100,000 km
Cases of 1 litre oil consumption per 2,000 km documented (at 89,000 km). The cause is usually a faulty crankcase ventilation or worn valve stem seals. Dealer workaround of switching to 10W40 does not fix the root cause.
Symptoms: Blue smoke trail especially in the first kilometres after cold start, no visible external oil leak, oil level drops noticeably between services
+ 1 more engine weaknesses + vehicle weaknesses
The 1.4-litre T-Jet extracts 150 hp from a small displacement via turbocharging and feels suitably lively once the blower is on boost. The mix of small capacity and plenty of boost works the engine hard: clutch and turbocharger are more heavily loaded, and over time the intake valves tend to coke up, blurring idle and throttle response. The water pump is a wear item, and a failed oil separator in the crankcase breather drives oil consumption up. Regular oil changes with high-quality approved oil and letting the turbo idle briefly after fast driving are important. Do that and it is a spirited, everyday-capable turbo petrol.
- !! Water pump wear from 120,000 km
The water pump on the 198A1000 is timing belt-driven and must always be replaced during a belt change. Water pump failure can lead to overheating damage.
Symptoms: Coolant loss, rising temperature, water pump squealing, coolant smell - ! Intake valve carbon build-up from 80,000 km
The 1.4 T-Jet 198A1000 uses direct injection, meaning the intake valves are not washed by fuel and accumulate carbon deposits. Build-up reduces charge filling and thus power.
Symptoms: Power loss, rough running especially when cold, misfires at low revs - ! Oil separator faulty, increased oil consumption from 90,000 km
The oil separator (crankcase ventilation) on the 198A1000 develops leaks or clogs over time. Oil enters the intake tract and causes increased oil consumption and engine contamination.
Symptoms: Increased oil consumption, oil mist in air filter housing, check engine light, boost pressure issues
Turbocharged 1.4-litre four-cylinder in bivalent autogas form, combining the low running cost of LPG with turbo torque. In sustained gas operation the thermally stressed cylinder head is a concern: intake valves tend to coke up unless valve-seat lubrication is fitted. The LPG injectors wear over time and degrade mixture formation, and the ECU adaptation for gas running can drift and cause power flat-spots. Regular checks of the gas system and a healthy oil level keep the turbo alive.
- !! Intake valve carbon build-up in LPG mode from 60,000 km
In LPG mode the fuel wash effect on the intake valves is absent, leading to heavier carbon build-up than on petrol alone. Regular injector cleaning is advisable.
Symptoms: Power loss especially on cold engine, misfires, rough running, poor throttle response - ! LPG injectors worn from 80,000 km
The gas injectors in the LPG system wear and need regular overhaul or replacement. Leaking injectors cause rough running in gas mode.
Symptoms: Reduced performance on gas, rough gas-mode running, increased gas consumption - ! ECU adaptation to LPG disrupted from 80,000 km
The engine management must relearn between petrol and LPG operation. Incorrect adaptations can cause idle problems and fault code entries, especially after workshop visits.
Symptoms: Check engine light after filling, rough petrol-to-gas transition, misfire fault code
A turbocharged 1.75-litre four-cylinder with direct injection and around 200 hp, technically related to the sporty Alfa unit. Punchy, eager to rev and with a clear sporting character, and chain-driven with no belt interval. The weaknesses are in the detail: a failed crankcase ventilation drives up oil consumption, a clogged oil filter screen can starve the turbo of oil, and the valve-cover gasket and camshaft-timing solenoid are prone to failure. The high torque works the clutch hard. Only worth buying used with a well-kept oil regime and a leak-free engine.
- !! Turbo oil supply blocked by filter screen from 60,000 km
The filter screen in the banjo bolt oil feed to the turbocharger can clog and cut the turbo off from its oil supply. Alfa Romeo recommends inspecting this screen at every oil change.
Symptoms: Sudden power loss, turbo whistling, pressure drop at high load, in the worst case total turbo failure - !! PCV membrane failed, high oil consumption from 70,000 km
The oil separator on the cam cover sticks or its membrane tears. Oil is drawn directly into the turbo and burned. Repair possible with silicone oil treatment of the membrane, then renew the cam cover gasket.
Symptoms: High oil consumption (up to 1 litre per 1,000 km), smoke from exhaust, oil in turbo intake area - !! Clutch overloaded at high torque from 80,000 km
The standard clutch in the 939B1000 is at its limit with higher torque. Sporty driving or light tuning quickly leads to clutch slip and wear.
Symptoms: Clutch slip under high load, poor engagement, clutch smell
