Hey Chris
If you run down the tach signal on the flexible circuit board and cut the
tach signal to the dynamic "L" relay in the Speedo then that relay will not
know that it ever reaches two thousand RPM.
Just be sure to cut at the right spot or you will disable your tach. As well.
I have done many of these on all type's of VW's, it was common practice at
the dealership (right or wrong) it fixed a lot of vehicles that people were
throwing relay's and oil pumps at.
Never saw any that really had any bearing problems before or after this fix
All the years I worked on VW's I never saw any bearing problems except the
one's that were run out of oil constantly.
