Well, this is partially correct because the first Mercedes-Benz hybrid was a bus: This section contains Mercedes-Benz W221 specifications. The ABC is really a conventional coil spring suspension with added hydraulic levelling. [2] In contrast to the port-injected M273, the M278 features gasoline direct injection, with piezo-electrically actuated fuel injectors for more precise fuel delivery, and multi-spark ignition, which enables the spark plugs to be fired multiple times over the combustion sequence for more efficient combustion. Also, watch out for worn camshafts. Pressertech is known for excellence in Performance Tuning. You won’t find any coil springs in Citroen cars with hydro-pneumatic suspension, and when a nitrogen sphere fails, there is virtually no damping in a Citroen car. Once fixed, they are not bad units. When a leak occurs, the gases and the diesel fuel from the combustion chamber can escape and cover the area around the leaking injector with burnt, hard, tar-like substance. All diesel engines in the Mercedes-Benz W221 S-Class have diesel particulate filters (DPF). Humming or howling noise between idle and 2000 RPM means that the pulsation damper has failed. Use forums to search for issues in the future as well! If the high maintenance cost doesn’t scare you, and you still want a car with the ABC suspension, look for a 2008 model or newer.

When there’s a problem with the intake manifold, the engine performance is reduced (increased fuel consumption, loss of power, poor idle), and the “Check Engine” light may come on. Additionally, over the years the plastic parts in the mechanism become weaker and more brittle.
If it drops in a couple hours, something is worn out or there is a significant leak somewhere. Thus, you can expect the maintenance costs to be accordingly higher.
