B7 RS4: DRC alternatives

[Hoddo]

Considering a B7 RS4. I am aware of the DRC issue and have a few questions.

By now a large number of B7 RS4s will have experienced the DRC issue and had the problem replaced under warranty at Audi (this correct?). Did the replacement solve the issue or was it like for like parts. I.E. the DRC issue could happen again?

When the problem occurs is it not sensible to change to a Koni or Bilstein set up? Is this a common solution by owners?

What is the best warranty for this car? One that covers the DRC and choking issues.

Anything else I should look out for?

If recently fitted DRC shocks have a problem, then that will be covered by Audi's own parts warranty which is either 1 or 2 years, I can't remember.

Good to know, had not considered that.

While it's a known issue, not all cars appear to be affected. My car currently has near 67k miles on the clock on its original DRC shocks. I do get it checked every service and admit I think myself lucky right now.

I was under the impression it was a matter of when rather than if the DRC failed. Again, interesting to know.

Would a warranty cover engine coking? For peace of mind I would get one to cover suspension.

Can you recommend any?

There's loads of detailed advice on RS246.com if you've not been there yet, including alternative suspension set ups, though personally I would stick with the original, it's the best IMO. I assume you've seen the recent buying guide here on PH?

I recently signed up to RS246 and shall have a read about alternative suspension set ups.

Interesting to read your points re: DRC. If however you know it will fail again at some point in the near/far future why would you persist with that option? Is it purely down to having the best suspension set up regardless of the potential costs?

They're great cars but, like any performance model, not particularly cheap to run. Good luck in your search (really good members' cars come up for sale on the forum and tend to have been well looked after).

I am researching this purchase with my eyes wide open. Fully aware of the costs, however if there is a way to minimise expenditure by sourcing a vehicle with a certain suspension set-up then I will.

Some interesting lowered RS4's on that site. Not exactly my cup of tea but each to their own.

Keep on eye on the shocks.

When they leak, how obvious is it? Are you looking for a serious leak or slight seeping?

When they go properly you'll see it and know about it.

I wouldn't get rid of it for any alternatives; it works bloody well and with the latest generation parts it's fairly reliable. Get friendly with a good specialist and the cost of fixing it is far less scary than it used to be too. There are I think 2 or 3 now with the tooling to charge it.

^^^^^^ definitely, especially via a good specialist (eg Unit 20 or MRC).

A quick Google shows that Unit 20 are only half an hour away. Jackpot. Don't have any excuse now.
