Also known as: vea, drive-e, b4204t vea, t5 engine, t6 engine, t8 engine, 2.0 drive-e, b4204, b4204t6, b4204t11, b4204t23, b4204t48

The petrol half of Volvo's modular 2.0-litre four — the Drive-E family, which replaced the company's five- and six-cylinder engines entirely. Every petrol Volvo since has been a version of this one: T4, T5, T6 and T8 share a block, and the difference between them is boosting and electrification rather than architecture. The diesel half is the D4204T, the same block with compression ignition.

The T6 is both turbocharged and supercharged — the supercharger fills in low-speed response and disengages once the turbocharger is flowing — and the T8 adds a rear electric axle. That layering is the diagnostic reality: a performance complaint on a T6 or T8 needs the boost source identified before anything is condemned, because the symptom differs completely depending on which system is at fault.

The recurring items are the direct-injection intake-valve carbon, the high-pressure fuel pump, and — on early examples — the timing belt driving the oil pump, which is an internal wet belt with the same failure consequences as Ford's and PSA's.

B4204T alone does not identify this engine. Volvo used the same designation for the modular 2.0 turbo four of the 1990s S40 and V40, which shares nothing with it. A pre-2013 car wearing that code is the older engine.

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.

What makes one worth reading:

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.
