Mercedes fixes diesel injector problems

Mercedes say that a new injector system for C Class and E Class diesels with the OM651 engine have now been fixed.

So extensive was the problem that many owners were waiting months for their cars to be fixed as Mercedes struggled with a mounting pile of broken cars and injectors that were failing.

Mercedes tell us that the problem was fixed with the release of new injectors later in 2010, but Cars UK readers have continued to complain about their cars needing multiple visits to dealers with injectors failing multiple times (that original story garnered more than 500 comments from disgruntled Mercedes owners).

So it seems that original fix in 2010 is still causing problems, with our readers still reporting failed injectors, so we’ve asked Mercedes for an update on the progress they’ve made with the injector problems.

Mercedes say that although they believe the 2010 fix solved the vast majority of injector problems, a new injector system has been fitted to Mercedes C and E Class cars with the OM651 engine since the start of 2012, and has now released a quality update to replace the injector system in any earlier cars that are still having problems.

The updated injector system will be fitted to customer cars on the next service if needed, but if anyone is still having problems they can contact their local Mercedes Benz dealers to get this addressed sooner.

We’re pleased to see Mercedes has finally got a handle on this issue.
