ECU AUDI A5 CABRIOLET 2014 Service Manual

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

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

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 servic ing 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 authorized Audi dealer or any properly
equ ipped and qua lified workshop. We st rong­
l y urge you to g ive your authorized Audi dea ler
