Opel Grandland X 1.5 Diesel

The PSA DV5 1.5 BlueHDi engine uses a secondary camshaft chain (separate from the main timing belt) that links the two camshafts. Early engines used a 7mm pitch chain that is prone to stretching over time. Symptoms include a rattling noise on startup and fault codes P0011/P0012. If the chain snaps, valves can contact pistons causing catastrophic engine damage requiring a full engine replacement (€4,000-6,000+). Stellantis acknowledged this issue and has extended warranty coverage to 10 years / 240,000 km for engines produced between October 2017 and January 2023, covering 100% of parts and labor if the car was serviced according to schedule. An upgraded 8mm chain kit is now available. The recall involves an oil and filter change, ECU software update, and an identification sticker. If buying used, verify this recall has been completed and confirm whether the upgraded 8mm chain has been fitted. The problem typically manifests between 60,000 and 120,000 km.

The SCR (Selective Catalytic Reduction) system on the 1.5 diesel is sensitive to component failures. Common faults include a blocked urea injector, faulty AdBlue level sensor giving incorrect readings shortly after refilling, and pump failures particularly in cold weather. Problems typically appear between 30,000 and 60,000 km. Symptoms range from warning lights and increased AdBlue consumption to complete engine start prevention. There is a recall for vehicles manufactured between October 2019 and March 2020 addressing urea injector blockage through an ECU software update. The AdBlue injector part costs around €80-120, but the full system diagnosis and repair including labor typically runs €300-500 at an independent garage. If the SCR catalytic converter itself is damaged, costs can reach €800-1,200.

The DPF on the 1.5 diesel can become blocked as early as 25,000 km if the car is used primarily for short urban trips, as the exhaust system never reaches the temperature needed for passive regeneration. Symptoms include the engine warning light, reduced power (limp mode), and black smoke. A forced regeneration at a garage costs around €100-150. Professional DPF cleaning costs approximately €250-300. If the filter is too badly blocked or cracked, replacement costs €800-1,500 including labor. There was a specific recall for vehicles built between February and June 2018 (3,108 vehicles) for defective DPFs that could crack. Regular motorway driving of at least 20-30 minutes at highway speeds significantly reduces the risk.

The EGR (Exhaust Gas Recirculation) valve on the DV5 engine tends to accumulate soot deposits, particularly with short-distance driving and low engine loads. Symptoms include reduced power, rough idling, increased fuel consumption, and engine management warning lights. Problems typically appear between 40,000 and 80,000 km. The valve can sometimes be cleaned (€150-250) rather than replaced. Full replacement including labor costs €350-700 at an independent garage. Preventive cleaning every 50,000 km is recommended by specialists.

The EAT8 automatic transmission (Aisin-sourced 8-speed) fitted to automatic variants shows weakness particularly in 2018 and 2019 models. Common symptoms include jerky gear changes at low speeds, delayed upshifts, and a noticeable thud during downshifts while braking. Problems can appear as early as 20,000-40,000 km, with a second wave around 80,000-100,000 km. A software update to the TCU (Transmission Control Unit) often improves behavior (€100-200). If valve body solenoids or servo seals are worn, repair costs range from €800-1,500. Complete gearbox replacement can reach €2,500 or more, but this is rare. Regular transmission oil changes every 60,000 km (not always in the official schedule) help prevent issues. Manual gearbox variants do not have this problem.

The electric tailgate on equipped Grandland X models has two common failure phases. Early problems (5,000-15,000 km) involve the contactless opening sensor and height programming, usually resolved through recalibration or sensor replacement. Later problems (35,000-50,000 km) involve worn gas struts and mechanical defects in the closing mechanism, particularly on 2017-2018 models. Sensor recalibration or wiring repair costs around €100-200. Gas strut replacement costs €150-300 per pair including labor. Complete drive motor replacement can reach €400-600. Regular lubrication of mechanical components every 30,000 km is recommended.

Several owners report premature 12V AGM battery failure, sometimes within 2-3 years. Symptoms include the start-stop system ceasing to function, undervoltage error codes, and difficulty starting. The Grandland X uses a high-demand AGM battery for the start-stop system. Replacement with the correct AGM battery costs €200-350 plus a battery registration procedure (€50-100 at a garage). After replacement, error codes need to be cleared. Using an incorrect battery type (standard instead of AGM) will cause recurring issues.
