Lancia Delta
Biturbo diesel with 190 hp — most powerful diesel unit in the Delta. Two sequential turbochargers for a broad torque band. Complex boost system increases repair risk and cost.
Biturbo king
140 kW 1.9 MultiJet biturbo — rare powerhouse with genuine driving character.
Engine Weaknesses 3
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
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
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
Vehicle Weaknesses 9
The M32 gearbox (GM/Opel) is known for weak bearings on the 6th gear shaft. Howling and whistling from around 80,000 km; gearbox rebuild or bearing replacement required.
Temperature switch or fan control faulty — engine overheats in traffic queues or at low speed. Thermostat can also stick.
The rear brake calipers on the Delta 844 seize from lack of use, as the electric parking brake requires little mechanical actuation of the rear brakes. Pistons corrode inside the caliper.
Isolated reports of front coil spring breakages, especially on vehicles with 18-inch tyres and sports suspension. A broken spring can damage the tyre.
Steering rack develops play — knocking when driving over uneven surfaces and when turning in. Adjustment or replacement of the steering rack required.
Actuator motors for the climate control system (temperature, air distribution or recirculation flaps) fail — climate regulation no longer works correctly.
Sunroof drain hoses block — water runs into the interior and damages electronics under the seats or in the footwell.
Wheel bearings wear prematurely on the Delta 844 compared with similar vehicles. Rear wheel bearings are particularly affected. Seized brake discs complicate removal.
Screws, nuts and panel seams start to rust after around 2 years. Metal connections and sheet metal brackets show corrosion faster than on German competitor models.
