Why might the turbo on your Mercedes Classe B 2.2 CDI fail?

On the OM646 engine fitted to certain Mercedes Classe B models with 2.2 CDI power, 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 overdue oil changes, a blocked air filter, or a damaged intercooler are all common causes of premature failure. Revving the engine hard immediately after a cold start — before the oil has had time to circulate properly — also accelerates wear on the turbo bearings.

Exchange basis and warranty for this Classe B turbo

This new turbo is sold on an exchange basis: in accordance with our Terms and Conditions, return of your old turbo is required. It is only collected after the new turbo has been delivered and fitted, so your Mercedes Classe B is never left off the road. A 12-month parts warranty applies, subject to fitting being carried out by a qualified professional. Payment can be spread over multiple instalments, in up to 10 instalments.

Fitting advice for your Classe B turbo

Before fitting the new turbo to your OM646 engine, carefully inspect the oil circuit: feed and return hoses, 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
