Iíve got a problem with my 1999 2.4 A4 30valve, its engine hesitation and rough idling .
I started surfing the net for info on Audi's with engine hesitation and found about 10 pages on the subject, a lot of which were quoting TSBís ( Tech Service Bulletins ) on MAFís ( mass air flow).
My previous car ( Seat 1.9se toledo) had 3 air mass meters in 3 years.
My questions are.
Are there long standing problem with air flow on VW/Audi.
How can air flow/metering be easily checked by a DIYer.
P.S has anyone got access to TSB 010102 (Oct01) for A4 2.8 sedan ( USA )
