A8 Front discs and Pads

[n1cka8]

Do you need the audi software box plugged in to activate the hydraulic caliper to change the pads and discs ?

Thanks.

Not on the front, you only need a computer for the rear to retract the parking brake servos.

I have 2005 a8 and was told you need to set new pad % in with a computer so the sensors are set correctly, can anyone confirm this is the case with front and / or rear pads as replacing myself if I don't need to plug laptop in.

Yes, to do the rears, because of the EPB.

Changing fronts is straightforward, leave the rears to a dealer/specialist unless you have vag-com.

Thanks dragondownsouth, a friend has vag-com so could you tell me if its easy and what I need to do for rear pads just in case I need to replace all? Wouldn't mind trying it myself if its not technically hard.

(REARS) Other than that, it's pretty generic.

I suspect you only have to enter the pad thickness for the wear warning to be accurate, but not for them to work, but I may be wrong.
When I do mine (probably later today) I will add the depth of the disc lip to the pad thickness so that the wear warning is not so belts and braces (designed for long life service regime)

Thanks for help and with this I've decided to buy my own ross tech vag-com and hope its as easy as it sounds.
