[Vwdiesel] relays.

Re:  Relays,

I've been having trouble with a MIL.  Good
'ole VAG-COM said intermittent glow plug
circuit.

Tried the "Output Test Function". Relay
clicked, for sure, but lights didn't dim
at all.

I removed the relay from the car.  I pried
it open *carefully* on the bench.  There
was a build up of a brownish material
(silver dust) inside the relay housing,
right next to the contacts.

I finished the contacts with 150 grit
sandpaper, and wiped the housing clean.
Should have used emory cloth, but didn't
find any.

Snapped it back together.  Same Vag-Com
"output test".  Lights dim now.  I
cleared the DTC's.  I'll know if it
works when I go driving tomorrow.

CAUTION: Finishing the relay contacts
like I did, screws the finish  on
the contacts.   The relay is more
likely to stick shut now.

If something breaks after you try this,
you get to keep the pieces  ;-)

If the DTC (MIL) light returns to normal,
I'll buy a new relay.  How much are they?

FWIW,
