1.6 HDi DV6TED4

The PSA small diesel in its Euro 4 form, sold across Citroën, Peugeot, Ford and Volvo. It's economical and pleasant enough, and its one real weakness is the narrow turbo oil feed, which cokes up when oil changes are stretched.

Overview

The 1.6 HDi is the DV6TED4 diesel version of the Citroën C4 Picasso MPV (Mk1), sold 2006–2013 with 110 PS and manual or automatic. Demands diligence at level 3. The turbo oil feed cokes up on cars with stretched oil changes, and the turbo goes with it. 4 failure modes are recorded against its engine, gearbox, chassis and shared components. Prices on this page are illustrative placeholders rather than a sourced market sample. See the methodology for how the bands are derived.

Known issues, ranked by expected cost

Faults recorded against this engine, its components and its chassis, ranked by likelihood × repair cost. Costs are indicative ranges with a stated labour basis.

DPF clogging and forced regenerationDPF€250–€1,800

Warning light, limp mode, oil level rising above the maximum mark from fuel dilution. The filter needs sustained hot running to regenerate. A car used for short urban trips never completes a regeneration cycle.

Check: Read the DPF soot load and the distance since the last regeneration on a scan tool, and check the engine oil level and smell it for diesel. Ask what the car was used for. A short-trip city diesel is the wrong car regardless of mileage.

EmissionscommonPartly detectableevidence: documented120–250k km

Turbo oil feed blockageDV6TED4 1.6 HDi€300–€1,500

A whine or rattle from the turbo, a loss of boost, blue smoke and eventually an oil-pressure or boost warning. 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.

Check: 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.

Turbo & intakecommonPartly detectableevidence: documented100–180k km

Variable-vane turbo actuator stickingvariable-vane turbo€400–€1,200

Sudden loss of power on a hard pull, limp mode that clears on restart, underboost or overboost codes. Soot binds the variable vanes or the actuator linkage seizes.

Check: Do a full-throttle pull in third from 1,500 rpm to the limiter. Hesitation or a drop into limp mode is this fault. Do this twice.

Turbo & intakecommonDetectable at viewingevidence: documented130–250k km

EGR cooler leakEGR cooler€400–€1,000

Coolant loss with no visible external leak, white smoke, sweet smell. The EGR cooler cracks internally and leaks coolant into the intake. BMW recalled affected diesels over a fire risk from glycol deposits igniting.

Check: Check coolant level and look for unexplained top-ups in the service history. Verify the recall was carried out. It's free and searchable by VIN.

3OBD scanMandatory. A seller who refuses a scan has answered the question.

DPF clogging and forced regenerationRead the DPF soot load and the distance since the last regeneration on a scan tool, and check the engine oil level and smell it for diesel. Ask what the car was used for. A short-trip city diesel is the wrong car regardless of mileage.

Mileage and servicing

What the odometer does and doesn't tell you here, plus the service items whose neglect causes the expensive failures above.

High mileage on this engine is fine when the oil record backs it. What the odometer won't tell you is how many of those changes happened on time, and that's the number that decides the turbo.

Service item	Interval	Cost
Engine oil and filter Stretched changes coke the turbo oil feed, which is the fault that defines this engine.	10,000–15,000 km	€80–130
Cambelt and water pump A belt failure here bends valves.	160,000 km or 10 years	€450–700

What that meansNo US band exists to compare. Any car you find there's a private import, parts and specialist knowledge are thinner, and the price says more about import cost than about the market.

US figures are the EU band converted at a stated rate. No US market differential is modelled: we hold no sourced US asking prices, and inventing one would be worse than saying so. What the comparison does show for real is availability. Most of this range was never sold in the US.

Buyer notes

Our judgement, kept separate from the records it's built on.

Our read, not a record

This is the engine most C4 Picassos were sold with, and it's a good one in a car this size provided you're not always carrying seven people. Read the service book before you drive it, since a coked oil feed starves the turbo bearing and debris can then travel through the engine. Listen for a whine on boost and look for oil in the intercooler pipework. So treat a thin folder as a reason to walk, because the engine itself is fine and the maintenance is what fails.

Everything above this line comes from the issue and specification records. This paragraph is our judgement on top of them. See how we reach it.
