BA-4 Bulletins

These service bulletins were sent out by Volkswagen as additions to the general heating service manual covering all models. They informed the shop about problems found with heating components or changes for new model years.

The scans on these pages were done by Russ Wolfe. You can find more bulletins for other heater models on his site at www.classicvw.org.

If you find a lot of grammar- or other errors in the bulletins don't be surprised. I reproduced the text as faithfully as possible. Back then they never seemed to use proof readers.
