BUYING A
VOLKSWAGEN T4.

Before You Travel

Ask for the registration, mileage, MOT status, engine details and enough clear photographs to decide whether the journey is worthwhile.

• Check the registration against DVLA vehicle information.
• Check the MOT history for recurring advisories, corrosion notes and mileage inconsistencies.
• Ask how long the seller has owned it and why it is being sold.
• For a higher-value van, consider a paid history check for outstanding finance, theft or write-off information.
• Ask whether the seller is private or trading as a business.

Paperwork, VIN & History

Make sure the van in front of you is the van described by the advert and paperwork. Compare the VIN/chassis number, registration and vehicle details with the V5C and available records.

• Check mileage against the MOT history rather than relying on the dashboard alone.
• Look for invoices and service records that support the seller’s story.
• Ask specifically about timing-belt work, clutch work, welding, cooling-system repairs and recent servicing.
• For camper conversions, ask who carried out the major electrical, gas or structural work and what records exist.

Bodywork & Rust

T4s are now old vehicles, so corrosion is not unusual. The important questions are where it is, how extensive it is and whether previous repairs were done properly.

Check these areas carefully

• Base of the windscreen and scuttle, including signs of water ingress.
• Front and rear wheel arches.
• Outer and inner sills, lower seams and jacking areas.
• Bottom edge and inner structure of the sliding door.
• Fuel-filler area and surrounding seams.
• Rear crossmember and areas around the rear spring seats.
• Floor, chassis rails, inner wings and outriggers where visible.
• Tailgate/rear doors and door bottoms.

Look for overspray, mismatched paint, heavy filler, new underseal and repairs with no supporting explanation. None automatically means a bad van, but all justify closer inspection.

Sliding Door, Windows & Seals

• Open and close the sliding door several times. It should move reasonably smoothly.
• Check the door for excessive vertical play and inspect the lower running rail.
• Check cab doors, rear doors/tailgate and locks.
• Look for water staining around the windscreen, side windows and conversion windows.
• Test electric windows and mirrors where fitted.

Engine & Cooling System

Try to see the van with the engine cold so you can judge cold starting, initial smoke and noises.

• Check fluid levels and look for oil, coolant or fuel leaks.
• Look at coolant condition and the expansion tank.
• Listen for unusual knocks, rattles, squeals or belt noise.
• Check warning lamps behave normally.
• Allow the engine to reach operating temperature and watch for overheating or coolant loss.

Haynes notes age-related T4 issues including instrument-cluster faults affecting fuel/temperature readings and electrical wiring problems. Treat strange gauges or warning lights as faults to diagnose, not folklore to ignore.

Clutch, Gearbox & Driveline

• Check clutch take-up and look for obvious slipping under load.
• Make sure every gear selects cleanly.
• Listen for whining, grinding, knocking or unusual vibration.
• Check for CV/driveshaft noises during full-lock manoeuvres.
• On automatics, check engagement and changes both cold and warm.

High mileage is not automatically a reason to reject a T4. Condition, maintenance and evidence matter more than one dashboard number.

Steering, Suspension, Brakes & Tyres

• Check tyre condition and uneven wear.
• Listen for suspension knocks on rough surfaces.
• Check steering for excessive play, pulling or unusual noise.
• Brake firmly in a safe place and make sure the van stops straight.
• Test the handbrake.

Electrics & Equipment

• Test headlights, indicators, brake lights, fog lights and reversing lights.
• Test wipers, washers, horn, heater fan and demisting.
• Check dashboard instruments and warning lamps.
• Test electric windows, mirrors and central locking where fitted.
• Look for loose aftermarket wiring, unfused feeds and unexplained switches.

Camper Conversion Checks

A tidy interior does not prove a tidy installation. Treat the conversion as a second inspection layered on top of the van.

• Check furniture fixing and signs of structural metal being cut or altered.
• Check pop-top/high-top condition, seals, catches and signs of leaks.
• Ask how the leisure battery is charged and where the principal fuses are.
• Check mains hook-up installation and available records if fitted.
• For LPG/gas equipment, look for appropriate installation and professional checking where relevant.
• Inspect added travel seats, seatbelts and their mountings carefully.
• Look for damp, staining, soft flooring and condensation damage.

The Test Drive

• Start from cold if possible.
• Use every gear and load the engine normally.
• Make sure engine temperature remains stable.
• Listen for wheel-bearing, suspension and driveline noises.
• Check braking performance and steering behaviour.
• Afterwards, look underneath again for fresh leaks.

Making the Decision

Judge the van against its asking price, condition, history and the likely cost of putting faults right. A cheap van that needs welding, tyres, brakes and major servicing can become the expensive van with impressive speed.
