The service training manual I have for the 1991 V8 describes the MAF as a self 
cleaning type. Plus the picture of it in the manual shows a cylindrical 
pickup like that shown for the Bosch self cleaning MAF. As to the wife's 1995 
A6 I'm not sure what type it is. The A6 has passed the emissions test without 
any problems, and runs smoothly, so it appears the MAF is working correctly. 
I'm going to check into what type of unit it has out of curiosity.
