Lancia Delta
LPG variant of the 1.4 T-Jet. Bivalent turbo operation with low fuel costs. Watch valve seat wear and the turbo in continuous LPG operation.
T-Jet with a green conscience
LPG barely costs any character on the 1.4 T-Jet — a sensible compromise with no loss of fun.
Engine Weaknesses 3
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
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
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
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.
