The ECU in my '83 UrQ was coated, but I still got a corrosion path at a
defect. It happened to be at an address line underneath  the ROM and it
caused strange behavior indeed.

Fortunately Audi inhibits the spark unless it occurs in a "window" of the
signal from the Hall sensor on the distributor. Once I discovered it, it was
easy to fix  I then baked the ECU in my oven and "conformal coated"  it with
Kylon clear.
