1. VW T5 (2003–2015)

• 1. EGR Valve and Turbo Problems
  The Exhaust Gas Recirculation (EGR) valve can get clogged over time, especially on higher mileage T5s. This can lead to loss of power and warning lights. Turbo issues can also arise due to carbon build-up.
• 2. Dual Mass Flywheel (DMF) Wear
  Although not incredibly common, there have been reports of rattling noises or vibration during gear changes, usually with particularly high mileage vehicles.
• 3. Electrical Faults and Central Locking Issues
  Owners occasionally report intermittent electrical problems such as malfunctioning central locking or dashboard warning lights.
• 4. Rust on Wheel Arches and Rear Doors
  Although newer than classic models, early T5s can suffer from rust, particularly around the wheel arches and tailgate.

2. VW T6 (2015–2022)

• 1. AdBlue System Faults
  T6 models introduced AdBlue technology for emissions control. Faulty sensors or crystallisation in the tank can trigger dash warnings and limp mode.
• 2. DSG Gearbox Hesitation
  The DSG automatic gearbox on some T6 models can develop jerky shifting or hesitation if not regularly serviced.
• 3. Water Ingress Around Windows and Roof
  Camper conversions, usually non-professional ones, may suffer from water leaks around pop-top roofs and side windows.
• 4. Heater and Air Conditioning Issues
  Faults with the HVAC system can cause weak airflow or failure to heat/cool the cabin properly.

3. VW T7 (2022–Present)

• 1. Software and Infotainment Glitches
  The digital dashboard and touchscreen systems can freeze or reset unexpectedly, often fixed with software updates.
• 2. Lane Assist and Driver Aid Sensitivity
  Advanced driver assistance systems can be overly sensitive, causing unnecessary alerts or steering corrections.
• 3. Interior Trim Rattles
  Some users report minor squeaks or rattles, usually in non-professional conversions once interior units are installed.

4. Maintenance Tips to Avoid Major Problems

• Regular servicing of the EGR, turbo, and DSG gearbox can prevent costly repairs.
• Check for software updates from VW to resolve T6 and T7 electronic glitches.
• Inspect seals and roof fittings regularly, especially if non-professionally converted.
• Treat and protect bodywork early to avoid the spread of rust.

Final Thoughts

Despite a few issues (as with any vehicle), the T5, T6, and T7 VW campervans remain some of the most popular choices for modern vanlife. With proper maintenance and awareness of these known faults, owners can enjoy years of reliable adventures on the open road.
