Problems with the check engine light and rough running engine in a Mercedes ML350

Hello everyone, I own a 2012 Mercedes ML350 V6 with a gasoline engine and 129,000 km mileage. For some time now, I've had the problem that the engine runs rough when starting, but calms down after a longer drive. In addition, the check engine light is on and the fuel consumption is increased. I've already been to Mercedes, and they told me it's the oil pressure, which would cause repair costs of about €4000. Has anyone had similar experiences or tips on how I could solve the problem more cheaply? Any answer would be worth its weight in gold. Thank you in advance!

A 2012 Mercedes ML350 owner is experiencing a rough-running engine upon startup, a persistent check engine light, and increased fuel consumption. Mercedes diagnosed the issue as an oil pressure problem, estimating repair costs at around €4000. Suggested solutions include checking and topping up the oil level, and considering an oil change if the oil is dirty, as low or degraded oil can impact oil pressure and engine performance.

Check the oil level and quality first, as low or degraded oil can affect oil pressure and engine performance. If the oil level is low, top it up and see if the issue improves. If the oil is dirty, consider an oil change. Let me know how it goes or if you have any other questions!
