The OM656 is an inline six-cylinder diesel engine used in various Mercedes-Benz models. Despite its advanced technology, several factors can lead to problems. From faulty software to mechanical defects – the causes of “OM656 problems” can be diverse. In the following, we will delve into the most frequent problems in detail and offer you concrete solutions.
Common OM656 Problems and Their Solutions
A frequently reported problem with the OM656 is increased oil consumption. This can be caused by various factors, such as worn piston rings or valve stem seals. An accurate diagnosis by a qualified mechanic is essential here. Dr. Klaus Müller, author of “Modern Diesel Engine Technology,” recommends a thorough inspection of the entire lubrication system in such cases.

Another known problem concerns the exhaust aftertreatment system, particularly the diesel particulate filter (DPF). Regular regeneration of the DPF is important to prevent clogging. Short trips and a high proportion of city traffic can impair the regeneration of the DPF and lead to problems. “Forced regeneration of the DPF can remedy the situation in some cases,” says Dr. Müller.
Problems with the Injection System
The complex injection system of the OM656 can also cause problems. Defective injectors or a faulty high-pressure pump can impair engine performance and lead to rough engine running. In such cases, replacing the defective components is often the only solution.
