I have a 1998 A6 2.5 TDI 2.5 V6 and it is supposed to have "ASR" and there
is a button on the dash for it. However it doesn't seem to do anything. No
light on the instrument cluster or anything.
Would I notice if this feature was working or not? And what would be
possible causes of it not working? I've checked with VAG-COM and the ABS
module doesn't have any faults logged.
No he doesnt hence the question,
ASR = Audi's traction control
Heres an extract taken from a website
Traction control (ASR)
For today's typical high-torque engines, a form of wheelslip
regulation or traction control (ASR) can increase both comfort and safety,
particularly on surfaces with differing coefficients of friction or on
slippery roads. It makes smooth starts and acceleration possible through all
speed ranges without wheel-spin or fishtailing.
ASR only operates in conjunction with the electronic accelerator
(E gas) and uses components of the anti-lock braking system (ABS). If one
wheel suddenly begins to rotate faster than the others (slip), ASR
intervenes in the engine management system and reduces power until the wheel
ASR improves traction and can help the driver maintain control
even if the limit of adhesion is inadvertently reached while cornering. In
addition, it reduces tire wear. ASR activation, is indicated by a flashing
light in the instrument cluster; it works with the electronic differential
lock (EDL) and it is also part of the electronic stabilization program
(ESP). ASR can be deactivated with the ESP switch

Thanks for your replies, I will try it out later - however from the manual I
was under the impression that pushing the ASR button on the dash would
temporarily disable ASR and the light in the cluster would come on to say
it's off. This doesn't happen on mine - and I'm trying to find out if it's
the button, lamp, or something more serious that isn't working.
Indeed... well I have been testing some things tonight, and so far it just
looks like the bulb is gone. Would anyone here like to hook up VAG-COM to
their ABS system and tell me what (if anything) happens in measuring block
003 and 004 when you push the ASR button?
