Turbo oil feed blockage
Attaches to DV6TED4 at engine level · Turbo & intake · carried by 2 variants across 2 chassis
Overview
Turbo oil feed blockage is a common fault recorded against DV6TED4 at engine level, typically from 100–180k km. It shows up as a whine or rattle from the turbo, a loss of boost, blue smoke and eventually an oil-pressure or boost warning. Where it's documented, the repair runs €300–€1,500 (€300–800 for the pipe and a turbo service; a replacement turbo costs far more, costs dated 2026-07), and it can be partly checked before you buy. 2 variants across 2 chassis in this database inherit it.
What happens
Symptom. A whine or rattle from the turbo, a loss of boost, blue smoke and eventually an oil-pressure or boost warning.
Cause. The narrow oil feed pipe to the turbocharger cokes up when oil changes are stretched or the wrong grade is used. The bearing then starves, and debris from a failed turbo can travel through the engine afterwards.
How to check it
Paperwork
Read the service book before you drive the car and treat stretched or missing oil changes as a turbo living on borrowed time. Listen for a whine on boost and check the intake pipework for oil.

Every variant that carries this
| Variant | Chassis | Body | Years | Risk | Good buy | Cost as % of good buy |
|---|---|---|---|---|---|---|
| 1.6 HDi DV6TED4 | Mk1 | MPV | 2006–2013 | R3 | €2,500 | 36% |
| 1.6 HDi DV6TED4 | T7 | hatchback | 2007–2010 | R3 | €2,250 | 40% |
The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
