Disadvantages of the Mercedes M177 engine
Initially, this engine is not very fond of tuning; its connecting rods are not strong enough;
However, if you maintain it properly, it won’t bother you and has a good service life in stock.
Even the use of Nanoslide coating in place of cast iron sleeves is problem-free;
Using only premium fuel is crucial to preventing injector failure;
On runs of up to 100,000 kilometers, some owners experienced oil pump failure; on specialized forums, they frequently complain about spark plug and ignition coil leaks and short service lives.
To replace the turbine oil pipeline and drain plug, a recall campaign was implemented.
