The Volkswagen T4 is widely regarded as one of the best Transporters ever built. Produced between 1990 and 2003, the T4 introduced front-wheel drive and a front-mounted engine, making it a major step forward from the T3.
Today, T4s remain hugely popular as campervans, day vans, workhorses and collector vehicles. However, most are now over 20 years old, so choosing the right one is essential.
Before You Start
When buying a T4, condition is far more important than mileage.
A rust-free van with good service history and 250,000 miles is often a better purchase than a neglected van with 100,000 miles.
Always buy on condition, maintenance history and overall care.

Both should have been replaced according to service schedules.
If there is no evidence of replacement, budget for immediate replacement.
Failure can result in serious engine damage.
Rust Inspection Guide
Rust is the number one issue with T4s.
Always inspect:
Front Wheel Arches
Look for:
• Bubbling paint
• Previous repairs
• Filler
Rear Wheel Arches
A common rust area.
Check both inner and outer arches.
Sills
Inspect thoroughly underneath.
Windscreen Surround
Hidden corrosion is common.
Front Steps
Check underneath rubber mats.
Bottom Of Doors
Look for corrosion around seams.
Tailgate
Particularly around the number plate recess.
Chassis Rails
Surface rust is normal.
Heavy corrosion can be expensive to repair.
Gearbox Checks
Manual Gearboxes
Generally very reliable.
Check:
• Smooth gear selection
• Clutch bite point
• No crunching between gears
• No whining noises
Automatic Gearboxes
Less common.
Ensure:
• Smooth shifts
• No hesitation
• Service history available
Suspension & Steering
Common wear items include:
• Wishbone bushes
• Ball joints
• Drop links
• Shock absorbers
Watch for:
• Knocking noises
• Uneven tyre wear
• Steering vibration
Brakes
Check:
• Brake pipes
• Disc condition
• Handbrake operation
Brake pipe corrosion is common on older examples.
Camper Conversion Inspection
If purchasing a converted camper:
Roof
Inspect:
• Canvas condition
• Water leaks
• Smooth operation
Interior
Look for:
• Damp smells
• Water damage
• Soft flooring
• Poor workmanship
Electrical System
Check:
• Leisure battery
• Split charge system
• Hook-up functionality
• Interior lighting
Gas System
Ask for:
• Gas safety certificates
• Evidence of maintenance
Service History
A well-documented service history adds significant value.
Look for evidence of:
• Oil changes
• Timing belt replacement
• Water pump replacement
• Brake servicing
• Coolant changes
The more history available, the better.
What Mileage Is Acceptable?
Mileage alone should never determine value.
A well-maintained T4 with 250,000 miles can often outperform a neglected example with half the mileage.
Focus on:
• Rust condition
• Service history
• Overall maintenance
Test Drive Checklist
During a test drive:
✓ Starts easily from cold
✓ No excessive smoke
✓ Pulls strongly through the rev range
✓ No gearbox noises
✓ Steering feels tight

VW Van Hub Verdict
The T4 remains one of Volkswagen’s greatest Transporters and continues to attract strong demand.
When buying, prioritise:
Rust-free bodywork
Service history
Timing belt evidence
Quality camper conversion
Overall condition over mileage
A solid, well-maintained T4 will almost always be worth paying more for and can provide years of reliable ownership.
Common VW T4 Problems
While the T4 is one of Volkswagen’s most reliable vans, there are a few common issues that buyers should be aware of.
Injector Pump Leaks (2.5 TDI)
The Bosch injection pumps fitted to many 2.5 TDI engines can develop leaks with age.
Symptoms include:
• Diesel smell around the engine bay
• Difficult starting
• Fuel leaks around the pump
Repair kits are available, but severe leaks may require a specialist rebuild.
Heater Control Problems
A very common T4 issue.
The heater control cables can snap, or the plastic inside the heater control knob can become brittle and break.
Symptoms include:
• Stuck on hot
• Stuck on cold
• Temperature control not working
Fortunately, repairs are usually straightforward.
Door Handle Failures
External door handles can wear over time.
Check:
• Driver’s door
• Passenger door
• Sliding door
• Tailgate handle
Replacement parts are widely available.
Cooling System Issues
The cooling system should be inspected carefully.
Look for:
• Coolant leaks
• Cracked expansion tanks
• Overheating
• Faulty thermostats
A healthy T4 should maintain a stable temperature at all times.
Alternator Pulley Wear
The alternator clutch pulley can wear and cause:
• Squealing noises
• Belt vibration
• Charging issues
This is a common age-related problem and relatively inexpensive to fix.
Worn Suspension Components
Most T4s are now over 20 years old.
Common wear items include:
• Wishbone bushes
• Ball joints
• Drop links
• Shock absorbers
A tired suspension setup can make the van feel loose and unstable.
Rust Repairs Hidden By Fresh Paint
Always be cautious of newly painted arches and sills.
Look for:
• Overspray
• Uneven panels
• Poor welds
• Excessive filler
A magnet can often help identify heavily filled areas.
Electrical Gremlins
Common electrical issues include:
• Central locking faults
• Electric window failures
• Interior light issues
• Faulty door switches
Most are simple fixes but worth checking before purchase.
Final Buying Advice
The best T4 is not necessarily the cheapest or the lowest mileage.
A rust-free van with good service history, documented maintenance and evidence of timing belt replacement will almost always be the better long-term purchase.
Take your time, inspect several vans and don’t be afraid to walk away from poor examples.
