High fuel consumption with A6
 

Hi,

I have a '99 A6 Avant 2.4 V6 (UK model). The fuel consumption has
always been poor (24-28mpg) but recently it has got worse (18mpg).
Before I pay a garage a load of money is there anything I should be
looking for?

I can't find a service manual for this car in the UK (Haynes don't do
one).

TIA, Mark.

Check the air filter, if its clogged up this could cause poor fuel
consumption,

Mark,
Chances are that something has gone awry, like an oxygen sensor, coolant
temperature sensor, or the like. There's probably a fault code logged by
the engine management system, you just have to read the code.
Unfortunately, your car probably requires a hookup and computer program to
read the codes, like VAG-COM. If you're planning to do most of the
maintenance yourself (electrical troubleshooting, etc.), then it may be a
good idea to invest in a reading program. http://www.ross-tech.com/ has
developed one that's cheaper than the one the dealer uses - they have
pricing on the web......wonder why the garage charges so much just to plug
one in?
The folks at Audiworld may have some suggestions as well.
Cheers!

Thanks again Steve for your response. I did think about a sensor
fault but I had assumed that there would be some kind of warning light
on the dash to indicate this. Is this not the case with Audi?

I've looked at the VAG-COM product, but it's a bit expensive for
occasional use. I guess I'll just take it the the garage. It's due a
service anyway.

Cheers, Mark.
