Engine Light On? Understanding Fault Code P06DA00 in Your Mercedes

Many Mercedes owners have encountered the dreaded illuminated engine light, accompanied by the cryptic fault code P06DA00. This code indicates a problem with the “Oil pump solenoid control circuit shorted,” leaving drivers concerned about their car’s health.

At Eurotech Autohaus, we have extensive experience diagnosing and resolving this issue in a range of Mercedes models. Here’s what you need to know:

The Problem:

The oil pump solenoid valve is crucial in regulating engine oil pressure. This ensures optimal lubrication and engine protection. Unfortunately, the wiring harness leading to this valve can become brittle and break over time, leading to the P06DA00 fault code.


Besides the illuminated engine light, you might not experience any other immediate symptoms. However, driving with this issue can lead to insufficient oil pressure, causing engine wear and potential damage.

Diagnosis and Repair:

Our expert technicians at Eurotech Autohaus utilize state-of-the-art diagnostic tools to pinpoint the exact cause of the P06DA00 code. We then carefully removed the engine oil sump to access the wiring harness and inspected it for damage.

If the wiring is brittle or broken, we replace it with high-quality components sourced from trusted suppliers. This ensures reliable oil pressure regulation and restores your engine’s optimal performance.
