Hello All,
It has been my recent experience to solve a cutting out problem I was having.
This can occur for a variety of reasons, but in this case, it was the Hall
control unit.

My engine management system is Digifant ll, which is 88-92 Jetta-Golf (I have
an I-4)
The 1.9 WBX has a Hall control unit also, which is the square black thing on
an aluminum heat sink on the left side firewall.

The cutting out came and went about two months ago.
Then it came back about two weeks ago, stalling me several times.
It just kept getting worse-the engine would stall and I would have to pull
over.
Well, I swapped the AFM first, with no effect. Then the Hall unit, and I just
came back on a 400 mile trip with no problems-looks like it was the Hall.
I didn't know they could fail intermittently but I do now. So anyone who's
engine has one of these units should carry a spare-it just might save your
vacation.
