Hi all, sounds a little like my problem (2001 TDI, 115): 1. I replaced the MAF about 6 months ago, performance was better, but I don't think that the MAF was totally knackered. 2. Occassionally, especially when under load, eg accelerating up a hill I loose my pulling power and get quite excited when I reach 30. 3. I can cure the problem by switching the ignition off and on again, though I don't like doing this uphill. the battery has been dis-connected so I think that the memory has been reset. ???????????????????????????????? any ideas ????????????????????????????????
