Here's a tour of the power relay 219 in the B5.5 Passat TDI.
Note the two contacts in the relay. One is obscured by the blue plastic.
If you unhook the spring you can gain access to the contact surface and clean as necessary.
I found quite a bit of oxidation had formed on the relay's external contacts. Inside, the contacts had obvious wear, but not enough to be conerned about. Deoxit 5, and a Deoxit Power Pen cleaned up most of the oxidation. I also sprayed a little D5 into the relay socket in the car, and applied an oxidation protector to the contacts during reinstallation. Hopefully this will extend the life of the relay.
At least it doesn't have bad solder joints like the A4 platform relay 109 was noted to have.
