Description
🔧 Product Overview
Original Mercedes-Benz OEM OVP relay, USED, tested, and fully functional.
This is NOT aftermarket, NOT reproduction, and NOT remanufactured — it is a genuine factory Mercedes part, removed from a classic vehicle and verified prior to sale.
The OVP (Over-Voltage / Overload Protection) relay protects sensitive electronic systems from voltage spikes and charging irregularities. On classic Mercedes models, a faulty OVP relay is one of the most common causes of intermittent electrical and drivability issues.
⚠️ Common Symptoms of a Failing OVP Relay
-
No-start or intermittent start
-
Random engine stalling
-
ABS warning light illuminated
-
Erratic idle or ECU behavior
-
Unexplained electrical faults
Replacing the OVP relay often immediately resolves these problems.
