DRC refill
DRC refill
Hello, anyone did it? Any ideas how much it can cost if it’s only front? And if all needed? Thanks
Re: DRC refill
Since the DRC circuits are diagonal across the car I fail to see how you think "it's only the front"!!
Re: DRC refill
It’s about £200-250 at Audi to replace fluid and pressurise
Re: DRC refill
Had mine done under warranty. As mentioned it’s a diagonally linked system with 2 valve assemblies at the rear and these can get damaged when pressure is lost.
I had knocking from the front right and rear left. Dealer refilled and pressurised (over 20+ bar) and has been OK since, so I may have been lucky and not damaged anything.

Not sure is it drc or something else, and this noise I get when I turn to the left hard when one wheel especially more higher than other, same sometimes happens when I turn to the right also when car not in horizontal position and one wheel higher than others

Re: DRC refill
Thanks for mentioning that, I definitely going to Audi dealer, that I have that noise and point them about that it could be drc refill time or these arb links. Or should I not mention them anything just tell that I have that knock sound, I can show on a video
P.S you mean those arb links in a picture I posted?
Or it’s this item https://m.autodoc.co.uk/ridex/8101055
Re: DRC refill
Yes those are correct. As you have DRC part no is 4H0411317C. I try to use a decent brand such as Lemforder, Febi, Meyle

Re: DRC refill
Same for me… I had mine done under warranty. It was only 2 bar under but had a noticeable knock on my rear left. Back up to 20+ bar and it went. Had the same issue with my RS4 B7. Tech at Audi said the knock is perfectly normal on DRC. Although my OCD on noises can’t cope with it!Rich85 wrote: ↑Sat Oct 15, 2022 10:59 pmHad mine done under warranty.

Re: DRC refill

Re: DRC refill
Agree 100%... the suspension shouldn't knock at all if everything is sound.. I've just found that out when I had a strut replaced the whole system drained and refilled..not a sound from it.Tadass910 wrote:So tech Audi said knock is perfectly normal?
