Common issues

Some of the main issues that linger in all M156 models consist of failure of the breather valve. The most common issue with the breather valve is that the diaphragm on the valve deteriorates over time. Another issue with the breather valve is that the hose from the crankcase to the valve also deteriorates and starts to crack. These issues can cause excess oil burning, heavy smoke from tail pipes and misfires. Other common issues are premature wear of engine lifters and camshafts as well as cam shaft adjusters. Common signs of this is a ticking noise at cold start of the vehicle. Other common issues consist of intake manifold failure, head bolt issues in models from 07 to 11 and drive belt pulleys.
