Hi, m8s!
This Mercedes is draining battery badly: 1.62A
By taking out the fuses I located that the main reason is instrument cluster. After disconnecting it the car is eating 0.14A
Another electricity eater is OCP. After taking out the fuse Nr.9 from the rear SAM the car eats 0.04A
So the question is: is it possible to fix the original cluster or I must to change it?
The cluster is working as it must, visually nothing burned or damaged on the PCB, nobody was changing the mileage.
Cluster VDO A211 540 55 11
Thank you!
