VW T5
Unit injector diesel with 77 kW, best-selling T5 entry engine. Solid base; PD unit injectors and dual-mass flywheel are wear items to budget for.
Small T5 Diesel
The 1.9 TDI AXB with 105 hp is a solid, frugal base engine in the T5. Adequate for light-duty work.
Engine Weaknesses 5
PD element sealing rings wear and allow diesel to enter the engine oil. PD overhaul is due approximately every 200,000 km.
Symptoms: Black smoke, power loss, poor cold start, oil smells of diesel
In the AXB 1.9 TDI T5, the high forces of the PD elements contribute to premature scoring of the camshaft bearings. Repair requires cylinder head replacement including the camshaft.
Symptoms: Grinding noise from valvetrain, oil pressure drop at idle, engine stumbling, cold start difficulties
Bearing shell wear from PD injection forces. At 277,000 km, scored bearing shells and burring on cam lobes have been documented.
Symptoms: Minor starting problems, rattling from valvetrain, metal particles in oil filter
Identical DMF problem as the AXC. VW dealer approx. 2,000–2,700 €, independent workshop approx. 1,000–1,700 €.
Symptoms: Vibrations and rattling at idle, grinding noise on clutch engagement, creaking on pull-away
The turbocharger suffers bearing damage when oil changes are neglected. Coked oil lines must be cleaned before fitting a replacement.
Symptoms: Whistling turbo noise under load, blue smoke, power loss, limp mode
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.
