Fuel stavation hestitation rough running 4000Q -- was feature of older Audis

[superba]

Hi All,

My 1981 Audi 5KT had an empirical low fuel warning:  If the tank were less
than ~1/4 full, there was fuel starvation in tight turns at any appreciative
speed.  That included freeway off ramps, but as soon as I was back on the
straight, the engine picked up again.  I decided it was a lack of baffles in
the fuel tank;  however, it was very disconcerting at times.

If the problem were the fuel filter, it would starve straight and level as
well as in turns...

I think this confirms what Huw said about his 1983, which was a later
version of the 1981 5K.

My .02.

Cheers!

Jim Jordan
