Frequently asked questions

Is the E-Tense reliable?

The system works well when maintained, but battery and charging faults are the costly failures.

Does it hold value?

No, depreciation is heavy, which makes it good buying stock but a careful sell.

What about the suspension?

Active Scan uses a camera to read the road; faults trigger warnings and a firmer ride.

Which engine is best for dealers?

The 1.5 diesel for motorway users, the plug-in for company-car buyers.

Are replacement parts difficult or expensive to source compared to mainstream rivals?

Despite the premium positioning, the DS 7 shares the EMP2 platform and powertrains with Peugeot and Citroën models. Mechanical and consumable parts are readily available and priced similarly to mainstream Stellantis vehicles. However, bespoke exterior trim, lighting units, and specific interior panels are dealer-only and carry a premium markup.

What is the correct replacement interval for the 1.2 PureTech timing belt?

Stellantis officially revised the wet belt replacement interval to six years or 60,000 miles, reduced from the original ten years or 100,000 miles. Dealers must ensure this has been adhered to, as degraded belts block the oil pickup, leading to catastrophic engine failure. Always verify correct oil grades were used.
