Opel Y22DTH / D223
2.2 L · inline-4 · turbocharged · diesel · 2000–present
Also known as: y22dth, y22dtr, d223, d223l, x22dth, 2.2 dti, 2.2 dti opel
The 2.2 DTI — Y22DTH at Opel and Vauxhall, D223 at Saab — in the Vectra, Omega, Signum and Saab 9-3 and 9-5.
⚑ It is one engine wearing two companies' codes, which is the useful thing here: a Saab owner searching D223 and an Opel owner searching Y22DTH are looking for the same parts and the same faults, and neither search finds the other's results.
It is a common-rail engine of the first generation and its recurring items are that generation's: injector seals that leak combustion gases and carbon the seat, making removal a job in itself; the EGR valve, which carbons shut; and the swirl flaps in the inlet manifold, whose linkage wears and whose failure sets a code that reads as a boost fault.
The turbocharger's oil feed pipe carbons up and starves the bearing — the commonest root cause of a turbocharger that has failed on one of these, and replacing the turbo without the pipe repeats it.
The 2.0 DTI beside it is a different engine with its own page here, despite the nearly identical badge.

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.
