Not sure you've found the right part?
Why might the turbo on your Mercedes B-Class 2.2 CDI fail?
On the OM646 engine fitted to certain Mercedes B-Class models in 2.2 CDI form, the turbocharger is put under particular strain by its variable-geometry vanes, which can become clogged or seize over time. Insufficient lubrication, poor-quality engine oil or oil that has not been changed on schedule, a blocked air filter, or a damaged intercooler are all common causes of premature failure. Driving with sharp bursts of acceleration immediately after a cold start — before the oil has had time to circulate properly — also accelerates wear on the turbo's bearings.

Before placing your order, please check the reference printed on your old turbo or on your vehicle registration document to ensure perfect compatibility with your vehicle.

Fitting advice for your B-Class turbo
Before installing the new turbo on your OM646 engine, carefully inspect the oil circuit: the feed and return hoses, the cleanliness of the lubrication passage, and the absence of carbon deposits or residue. Also check the condition of the air intake and intercooler, as well as the integrity of all boost hoses. When starting up, prime the turbo with oil before the first engine start to ensure immediate lubrication of the bearings and prevent any dry running.
- Check the air filter and replace it if necessary
- Check for any oil leaks or vacuum leaks
- Follow the manufacturer's recommended oil change intervals
- Drive gently after a cold start
