Lancia Delta
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.
Entry-level turbo
88 kW T-Jet with 200 Nm is enough for fluid driving — adequate, but the stronger variants show the true potential.
Engine Weaknesses 4
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 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
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
Well-known ignition coil failures on the T-Jet at around 100,000 km — after replacement, another coil can fail within two weeks. Missing power especially in city traffic and at low revs.
Symptoms: Engine warning light, noticeably reduced power (feels like 80 instead of 120 hp), judder and stumble at low revs and in city driving
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.
