98 A4 1.8 Avant Auto Questions
I have just bought a lovely example of a 1998 A4 1.8 Avant Auto, with
lots of extras to the SE Spec. Full Audi service history, 60k miles.
Really happy with the car except for a couple of questions that dont
seem to be answered by the owner's handbook:
1. Sometimes the Radio/CD/Tape cuts off and a loud beeping starts
coming through the car audio system beeping once a second getting
louder and louder. The only way to stop it is to turn off the Audio
system. The car is fitted with the top-spec Audi+BOSE system if that
makes a difference.
2. After driving for a while, taking foot off of the accelerator, the
engine idles very roughly. Moving gear lever from D to N makes no
difference. Revving the engine (in N, of course) for a few seconds
lets it settle down and idle properly. My VW Golf used to do this as
well and could never figure out why. Any Audi experts seen this
before?
3. Fuel economy seems to be about 30mpg according to the computer.
Measuring miles and litres of fuel at the pump indicates about 28mpg.
Is this about normal for this vehicle?
4. Have seen various mods advertised that fool the ECU into thinking
the air from the air intake is cold, supposedly giving +10BHP
improvement. Anyone had experiance of these mods? Is 10BHP Noticable?
Do they damage the engine/cat?
Many Thanks
Andy

Think its somthing to do with "TP" try turning off TP and see if it goes
away, it happens because your stereo loses partial signal. I have yet to
find a resolution for the problem

Sorry I got a manual maybe a faulty idle control valve?

A bit low, unless its all town driving, I drive mostly on Motorways and av
28mpg, 2.6 v6 Quattro

I have noticed this also, on cold days my car has loads more power, when its
below 10c the acceleration is great, in the summer its sluggish. This mod is
somthing I may look into unless I get rid of the car soon. I thought it only
effected the V6 model's ?

The beeping occurs because you have TP selected, but the station you
are tuned to doesn't carry the traffic announcements (or the
transmission is too weak to detect the TP marker). The two possible
solutions are to turn TP off, or re-tune to a station which does carry
traffic announcements.
