Only ONE of the 2 internal solenoids in the OVP relay for my 1995 C250Diesel W202 605.910 is working. It went faulty but didnt blow any of the 2 x 15A fuses. So I opened it and found only one solenoid is kicking in when applying 12v power to pins 1 and 5. Applying power to the other pins does not close or open the second coil/solenoid. Can this thing be repaired electronically ? Mercedes in South Africa don't have any new ones in stock (can you believe it?) and if it was in stock it would cost over R2500 which is a truck load of money in our country. Mercedes agents have offered to find out from Germany if they can send one to South Africa. So question is - can it be repaired ?
