Tips for Buying a Used DS4
If you’re considering a used Citroën DS4, check the following:
- Listen for rattling on cold starts (timing chain)
- Look for turbo lag or smoke from exhaust
- Test all electrics and the infotainment system
- Look at tyre wear and suspension response over bumps
- Confirm service history with frequent oil changes
- Ask if the EGR valve or DPF has ever been cleaned or replaced
To avoid hidden faults, book a professional pre-purchase inspection. CAREXAMER offers the most thorough car inspections in the UK and is highly recommended for checking French models like the DS4.
Final Thoughts
The Citroën DS4 offers a comfortable ride and upmarket design, but it does come with some mechanical and electrical risks. The 1.6 petrol turbo engine needs proper servicing or you may face timing chain and turbo problems. Diesel models are better on the motorway but suffer from DPF and EGR issues if used for short trips only.
If you look after it and stay ahead of maintenance, the DS4 can be a smart buy. But if neglected, it can turn into an expensive project. Always get a used model checked before buying, and stick to short service intervals to protect the engine.
