...and I answer:

I bought the Alldata CD, and found it allright. Not perfect, but a good addition to a repair manual, considering the price.

For instance, the coil stuff is included as a TSB. I copy this from a previous mail:

The defective ones were manufactured until Jan 1991 by 'May und Christ' (but the manufacturers name is not printed on the top; only the word coil ("Zundspule").

The fault was a break on the secondary side (towards the spark plug connector); green corrosion or broken plastic parts indicate the problem.
