Mercedes-Benz V6 and V8 engines had timing chain problems caused by balance shaft and idler gear failures. Mercedes produced certain models with defective gears in their balance shafts (M272 engines) or with defective idle gears ( M273 engines). These faulty gears wear out prematurely, excessively, and without warning, causing the vehicle to malfunction, the ‘check engine light’ to remain illuminated, and the vehicle to misfire or stop driving. A lawsuit was filed against Mercedes-Benz.
Timing chain failures can cause catastrophic engine damage. Early signs of this problem are the check engine light and engine noise. If the timing chain fails, the pistons can hit the valves and cause severe damage to the engine. Engines with the balance shaft worn sprocket were Mercedes-Benz 350 models (Example: E350 C350 etc. ) that were equipped with the M272 engine. Mercedes-Benz engine is typically labeled as 450 models that have the V8 M273 engine had problems with worn guide idler gear. The parts themselves are not very expensive, but they are very costly to replace.

Mercedes Benz has been using timing chains in their engines since the 1950’s. The purpose of the timing chain is to synchronize the camshaft and crankshaft rotation so that the engine’s valves open and close at the correct time. This is how your engine manages the combustion and exhaust process. Without it, your engine will not run.
Mercedes has chosen to use timing chains instead of timing belts because they are more durable than the rubber alternative. But like all moving parts, they eventually wear out and need replacement. Read More »
