DS 4 1.6 E-Tense 225 Mk2

Multiple owners report the 10-inch touchscreen and digital instrument cluster freezing or going completely black, sometimes mid-journey. The issue typically resolves after a full power cycle (stop engine, wait, restart), but can recur frequently. The DS Iris voice assistant has a documented failure mode where it stops working entirely after an over-the-air software update and does not recover with subsequent updates. One owner's car spent three months at a dealer waiting for a software fix. Dealers acknowledge this as a known issue but often cannot resolve it locally, directing owners to wait for future OTA fixes. While not safety-critical in most cases, loss of speedometer and climate controls during driving is disruptive. Software updates have addressed some cases, but others persist for months. Cost is usually zero if resolved by a software update; hardware replacement of the head unit or control module runs around €500-800 including coding.

The DS 4 E-Tense uses two 12V batteries (one under the bonnet, one under the rear armrest). Some owners report the hybrid battery losing 10-15% charge overnight, with the MyDS app identified as a likely drain source through background refresh and location tracking. Disabling background app tracking typically resolves mild overnight drain. In more serious cases, the P1059 fault code appears with 'electric drivetrain failure' warnings after the 12V system drops too low. The LVNSD module (low-voltage network supply device) manages the secondary battery and can fail, requiring replacement. If the 12V batteries themselves are degraded, expect €100-250 each. LVNSD module fuse inspection and replacement adds another €100-200 in labor. A trickle charger is strongly recommended if the car sits unused for more than a week.

The single-phase 7.4 kW onboard charger can fail, preventing the car from charging the traction battery. Symptoms include the charge process starting but stopping after a few minutes, or the car refusing to begin charging at all. Diagnosis requires dealer-level software to distinguish OBC failure from a simple cable or EVSE fault. Replacement cost is approximately €2,500 for the part alone, with labor adding €500-800 due to the unit's location. This issue is shared across the Stellantis PHEV family (Peugeot 308 PHEV, 3008 Hybrid, DS 7 E-Tense). Early cars within warranty receive free replacement, but out-of-warranty repair is expensive.

Owners widely report that the real-world electric range of the DS 4 E-Tense falls significantly below the WLTP claim of 55 km. New cars typically achieve 35-48 km in mixed driving, and this can drop to 25-35 km after 2-3 years of use. While some range loss is normal for PHEVs, the 12.4 kWh battery is relatively small, so even modest degradation is noticeable. The battery is warranted for 8 years or 160,000 km with a 70% capacity guarantee. If the battery falls below the 70% threshold within warranty, DS covers replacement or reconditioning. Out-of-warranty, traction battery replacement quotes range from €4,000-5,000 for refurbished units at specialists, while dealer quotes for new packs can exceed €10,000. For most owners, the range simply becomes shorter rather than requiring outright replacement.

DS recalled 3,202 DS 4 and DS 7 models built between February and May 2023 because the temperature sensor on the supplied charging cable was incorrectly calibrated. This could allow the cable to overheat during charging without triggering the safety cut-off, presenting a fire risk. The remedy is inspection and replacement of the cable at no cost under the recall campaign. If buying a used E-Tense from this production period, verify with DS using the VIN that the cable has been checked or replaced. If the original cable was lost and needs purchasing separately, budget around €150-200.

Several DS 4 and DS 7 owners report the car alarm going off at random intervals, sometimes in the middle of the night. The alarm siren sounds without the indicators flashing, which points to the siren battery or internal sensor rather than an actual security event. Common causes include a degraded backup battery inside the alarm siren unit, a corroded connector, or overly sensitive interior motion sensors. The fix is usually inexpensive: deactivating the internal motion sensors via the dashboard button, replacing the siren battery (€50-100), or cleaning and resecuring electrical connectors. If the alarm module itself needs replacement, expect €200-400 including labor.

A February 2025 recall affected DS 4 MHEV and PHEV models manufactured between March and September 2024. A weakness in the crimping of the quick coupling on the high-pressure fuel pump can cause a fuel leak in the engine compartment. Around 2,100 vehicles worldwide are affected. The fix involves inspection and replacement of the affected fuel line at no cost under the recall. Earlier E-Tense models are not affected. Verify recall status with a DS dealer using the VIN.
