Volvo VEA diesel (D4204T)

2.0 L · inline-4 · turbocharged · diesel · 2013–present

Also known as: d4204t, d4 engine, d3 engine, vea diesel, 2.0 drive-e diesel, d4204

The diesel half of Volvo's modular Drive-E family — the same 2.0-litre block as the petrol B4204T, sold as D3, D4 and D5, and the engine that ended Volvo's five-cylinder diesels.

The D5 of this family is twin-turbocharged and the D4 is not, which is the first thing to establish on a boost complaint: they are not the same installation, and a procedure written for one does not describe the other. Volvo's PowerPulse system on later D5s stores compressed air to spin the turbine off idle, and it is a component that can fail on its own while the turbochargers are healthy.

The recurring item is the internal wet timing belt driving the oil pump — the same arrangement, and the same consequences, as Ford's and PSA's: it degrades into the oil and blocks the pickup. Beyond that, the diesel particulate filter and the EGR cooler behave as they do on any modern 2.0 diesel, and the high-pressure fuel pump is the common hard failure.

Do not read D4204T on a pre-2013 car as this engine. Volvo used the same designation for the Ford/PSA-derived 2.0 diesel in the C70 and S40 of the previous decade, which shares nothing with it.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

The car — make, model, year and engine. The same fault behaves differently on each.
What you measured, not only what you replaced.
What actually fixed it — or that nothing did, which is worth knowing too.
