complexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, safe ty and e nvir onm en tal con­
cerns place very strict limits on the nature of
repairs and adjustments to engine and trans ­
miss io n pa rts which an owner can perform .
Maintenance, adjustments and repairs usua lly
require special tools, testing devices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliability
of your vehicle and even void your vehicle war­ ranty. The refo re, p roof of servici ng in accord­
ance w ith the maintenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, crea ting unnecessary risks for you
and your passengers.
If in doubt about any servicing, have it done
by your authori zed Audi dealer or any other
properly equipped and q ualified workshop .
We strong ly urge you to give you r a uthorized
Audi dealer the opportunity to perform all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, or iginal parts
and trained spec ialists to keep your vehicle
running properly .

ber of procedu res which can be performed on

b le. Before performing any of these proce­
dures, always tho roughly read a ll of the app li­
