The dual-clutch automatic can become hesitant or jerky if clutch wear is present or fluid changes have been skipped.
- OM651 Diesel Timing Chain Tensioner Oil LeakModerate
The gasket on the timing chain tensioner is a frequent leak point. Oil loss can reduce tensioner pressure and lead to chain rattle and eventual stretch.
