VW Transporter Problems What To Know Before Buying
The Volkswagen Transporter is one of Europe’s best-known commercial vans, prized for its practicality and reliability. From tradespeople to campervan enthusiasts, the Transporter—especially the T5, T6, and T6.1 generations—has earned its reputation. However, like any long-running model, it’s not without its faults. Below, we cover the most common VW Transporter problems, how to identify them, and recommended fixes.
1. EGR Valve and DPF Issues (Diesel Models)
Diesel engines in VW Transporters—especially the 2.0 TDI—can suffer from:
- Blocked diesel particulate filters (DPF)
- Faulty EGR (Exhaust Gas Recirculation) valves
- Engine management warning lights
- Power loss or limp mode
Fix: Regular motorway drives help keep the DPF clear. If mainly driven in town, consider a professional DPF clean. EGR valves can be cleaned or replaced if sticking or clogged.
2. Timing Belt and Chain Wear
Different engines come with timing belts or chains. Common symptoms of wear include:
- Rattling on cold starts (chain engines)
- Belt wear ahead of schedule
- Misfires or poor engine performance
Advice: Replace timing belts according to VW’s service schedule—typically every 60,000–100,000 miles. Chain systems should be monitored for noise and tensioner issues.
3. Dual Mass Flywheel (DMF) Failure
Common in manual versions of the Transporter:
- Vibrations through the clutch pedal
- Clunking noises when shifting gears
- Difficulty starting or engaging gears
Fix: If diagnosed early, a DMF and clutch kit replacement will resolve the issue and prevent gearbox damage.
4. Water Leaks and Drainage Blockages
Water ingress can happen via:
- Poorly sealed windows or roof panels
- Blocked scuttle drains
- Failed door seals
Tip: Check for damp footwells and window seals. Clean drain holes around the windscreen and sliding doors regularly to avoid long-term interior damage.
5. Gearbox Issues
Problems have been reported in both manual and DSG automatic transmissions:
- Jerky gear changes
- Slipping or delayed engagement
- Gearbox warning lights
Fix: Service DSG gearboxes every 40,000 miles with approved fluid. Manuals should have their oil inspected at major intervals. Diagnostic scans can pinpoint sensor or control module faults.
6. Turbocharger Problems
Signs of turbo wear include:
- Whining noise on acceleration
- Excessive exhaust smoke
- Poor performance or turbo lag
Fix: Leaks in the boost pipe system or worn turbo bearings are common causes. Turbo units may require reconditioning or replacement.
7. Suspension and Steering Wear
Frequent heavy loads or poor roads can cause:
- Clunks and knocking from the front end
- Premature tyre wear
- Unstable steering
Solution: Inspect ball joints, wishbone bushes, shocks, and top mounts. A four-wheel alignment is essential after any suspension repair.
8. Electrical Issues
Typical electrical faults in VW Transporters include:
- Power window or locking faults
- Infotainment glitches
- Random warning lights
Advice: A diagnostic tool will help locate the issue. Most problems are traced back to worn modules, corroded connectors, or software bugs.
Buying Advice: Get a Professional Inspection

Conclusion
The VW Transporter is a robust and versatile van, but like any vehicle, it has known weaknesses. Understanding the most common problems—particularly around emissions systems, gearboxes, and suspension—can help extend its life and reduce running costs.
With regular servicing, timely repairs, and careful checks, the Transporter remains one of the best vans on the market for business and leisure alike.
