Problem with Rear SAM Module for Mercedes W164 (ML280 CDI) - corrosion

If you have problems with rear lights, break lights, interior lamps, rear parktronic, the most common reason for this is a corrosion or water in the rear SAM Module. In my case it was just corrosion on two spots but there was also water under the Module as well. I removed the water and I opened the hole under the module which was blocked from a rubber stopper.
IMPORTANT: there is a sequence when remove the Module
1. Remove the battery
2. After an hour remove all connectors (the largest one) and at the end the smallest connector.

I implement also a four layers of a fluid which will keep the board from moisture, water and corrosion. The name of the product is V-66 Insulating Lacquer. You can use also fluid 101 I think it has the same properties.
