brake pads warning light

[kungfupanda]

I've recently done the rear pads and discs on my D4. The Pagid ones at ECP fitted with no problems and are performing well. New wear sensors are included with the new pads. Just to confirm on my 3.0 TFSI, there are wear sensors on the rears too. Just on one side though.

Any feedback on brake dust from the pagid or brembo options ?
Genuine pads seem to be mostly made by Ferodo by the way.

Hi,
Did you do that yourself - any feedback on how difficult it was. I have plenty of experience changing pads and discs on older cars and wondering whether I can do discs and pads all round myself rather than paying the stealer (£1600)

Yeah I did them myself. I've only done the rears though. I think they're trickier than the front. It's just the same as on any vehicle except you need VCDS or a generic code reading unit to allow you to wind back the callipers. Once the callipers are wound back, you release and remove the sliding pins, remove the caliper and then wind back the callipers with a wind back tool.

Remove the calliper carrier and disc then refit all. You don't need any special tools just the usual tools you'd need for any brake change.

Nice one - thanks very much. Appreciate the info - sounds like I now have an excellent excuse to buy a VCDS as well as saving some money on the brakes!

can you tell , did you input new pad thickness pad values in vcds after you changed them ? if yes where exactly and what procedure you fallowed ?

i ordered set for front and back, pagid pads, all together(front +back) with promotion code and delivery came to £90 from ECP

[kungfupanda]

I used a generic OBD tool to wind back the pistons and then wound them back on again once I'd finished. I know that VCDS asks you to enter the new pad mm thickness but I wasn't asked with the tool I used.

Do a search on youtube on guides to change rear pads on later Audi models. I think C7 A6's have the same procedure.

update on whole procedure.

i have changed front and rear.

front: no issues, just to remember wear sensors are not icluded in set, luckily mine sensors were ok, you can buy them seperate for cost of around £8. changing procedure as any other braking system, release 2 caliper nuts and one on outer side of caliper. caliper will come off, change pads and put everything back together.

rear: release parking brake - in vcds, controller 53(parking brake) -my controller is working in UDS protocol - so go to basic settings - from drop down list choose 'start linning change procedure' - you will hear parking brake winding all way back and screen shows 'running' - once screen shows 'not running' - go out from controller- close vcds - turn off ignition - you will notice parking brake button and 'P' on dash will flash - also don't worry if during changing process both lights stop flashing, it is energy saving feature. - next thing changing pads - well piece of cake - remove 2 nuts from back of caliper - and now before you remove caliper - use flat bar or big flat screwdriver put it in between old pad and caliper on outer side of wheel hub and pry on it and your piston will go magically back and you don't have to use later any special tools and caliper will be ready to take any size of pads and new disc. i had both sensors broken on back and they are included with pads, swap them. after you changed rear pads on both wheels put ignition on press brake pedal few times until feels hard open vcds module 53 - basic setting - from list choose ' end of lining change process' you will hear again parking brake working again and wait until vdcs shows 'finished' - parking brake button and 'P' on dash stops flashing - engage parking brake through button then release and engage again - now in vcds go to 53 module erase all faults, if everything is done correctly, faults will be gone and won't come back- also go to module 08 abs clear all faults and to module 01 engine and clear all faults. go for ride and enjoy new pads. JOB DONE!


one thing - i forgot about brake fluid so when i push pistons back brake fluid came out through tank lid and went through drainage on driveway. as fluid is corrosive i used luke warm water with fairy liquid and washed tank and flushed drainage.

second thing - i didnt hook up battery charger for whole procedure but I advise you to do it.

i took us 40 minutes to do front and rear.
