VW T5
Naturally aspirated with 85 kW, robust and low-maintenance. Power output borderline for the heavy van, especially loaded.
Basic Van Engine
The 2.0 AXA petrol with 116 hp in the T5 I is a simple, reliable van engine.
Engine Weaknesses 5
The ceramic substrate of the catalytic converter can disintegrate at higher mileages. This causes massive power loss even though the engine sounds normal.
Symptoms: Massive power loss, rpm drops sharply from about 4,000 rpm, engine warning light illuminates
Blocked crankcase ventilation hoses lead to elevated oil consumption of 1 L per 1,500–3,000 km. Particularly pronounced with short-trip use and LPG conversions.
Symptoms: Elevated oil consumption, oil visible in intake tract, bluish smoke on cold start
The EGR valve carbons up in short-trip operation and causes rough idle and starting problems. Cleaning is often sufficient, replacement required with heavy deposits.
Symptoms: Rough idle, difficult starting, power loss in the lower rev range, engine warning light
The ignition coils of the AXA are a known wear item. Individual failures cause misfires on individual cylinders. Ignition leads and spark plugs are usually due at the same time.
Symptoms: Engine stumbling under load, noticeable misfires, elevated fuel consumption, engine warning light flashing
The ignition coil of the AXA 2.0 T4 cannot withstand sustained thermal load. Coil and distributor faults account for around 80% of ignition problems in T4 engines.
Symptoms: Misfires, engine running on fewer cylinders, hesitation on acceleration, engine warning light
Vehicle Weaknesses 9
The EGR cooler breaks down internally and releases aluminium particles into the intake tract, which can cause engine damage. Coolant loss with no visible leak is a typical early sign. Repair costs €1,100–2,200.
Door seals with metal cores have sharp edges that damage the rubber. Penetrating water corrodes the metal beneath. The powertrain subframe under the engine rusts heavily. Early model years affected from approximately 4–5 years old.
Rear coil springs typically break at the top coil without warning for the driver. Vehicles of all model years affected from 50,000 km. Aftermarket springs often don't fit — use only genuine VW springs. Cost €160–400.
Due to the high vehicle weight, shock absorbers wear noticeably from approximately 90,000–130,000 km. Rust on damper mounts on older models. Strut mounts creak when turning. Complete replacement costs approximately €900–1,400.
The gear linkage cables dry out and become stiff. On 6-speed gearboxes the shift head bolt on top of the gearbox comes loose. Cable lubrication for approximately €40, shift head repair kit approximately €40.
When the 2.5-litre TDI water pump fails it expels coolant externally via a hose near the right driveshaft. Water-in-oil contamination possible. Replacement costs approximately €300–600. White residue on the pump is an early warning sign.
On the T5 7H/7J the sliding door lock fails due to broken plastic parts and springs inside the lock. Since the lock cannot be dismantled into individual parts, complete replacement is required. Cost €51–92.
The 'save' microswitch in the electric sliding door sticks or fails, preventing opening and closing. A defective anti-trap sensor also permanently stops the door. Repair approximately €200 (switch approximately €5, mostly labour).
On the T5 7H/7J, the headliner backing separates from the foam from approximately 150,000 km due to foam ageing. Initially the edges above the windscreen drop, then bubbles and sagging areas spread further.
