RS4 B7 Potential Purchase
Discussion
Hi I am looking at getting an RS4 B7 this weekend, im use to Audis Ur Quattros and RS2s and the cost of keeping them running in fine fettle, just wondering if any one can tell me the main points to look out for. I know about the Aux & Oil coolers that they rust through and aleak and that the pipes are a bit rubbish. It also has DRC suspension, which i would really like keep on the car.
So if you can add anything else to what i need to look at please, would really be appreciated it.

I'm looking at the S5/RS5 V8 so the coking thing is at the forefront. The engines aren't that dissimilar from what I can tell.
From what I can see, it's not the "cleaning" per se, but more so the removing of the hardened crud - so walnut blasting (circa £800).
High-pressure fuel pumps appear to be an alert.
The balljoints (iirc, the top one) can be a bit of a pig too - ie looking at rubbers etc to be replaced.
Aside from that, the Audi passenger door lock actuator (ie it needs replacing because the door won't open from the outside)......
They seemed pretty good tbh.

Thanks for the pointers, is the door lock actuator issue only specific to the RS4?From what I can see, it's not the "cleaning" per se, but more so the removing of the hardened crud - so walnut blasting (circa £800).

There's at least one other thread on here from the last week on the topic...and also a PH buyer's guide.

DRC...dampers can let go. Pipework rusts. Cylinders can fail.
Coolers as noted. Audi using two different metals in their wisdom.
Check when the brakes were last changed (budget £1k or so per axle. Maybe more).
Check for rust generally on the undersides and in the panels...as an example, the door blades can rust and I believe are hard to get hold of.
Great cars. But the newest will now be 14yrs old. Condition more than mileage as ever....and look through the history. If it has none, or it's patchy, walk.

Have you driven one? I borrowed one 10 years or so ago. I was tempted to buy one but I found it a little underwhelming. Yep it felt like a tank and made some nice noises but it didn’t feel particularly fast or fun and felt heavy. Nice but didn’t excite me. I’d been a massive fan until that point.

Thanks for your input, the front discs and pads were done 1000 miles ago and the rear discs and pads have just been changed. As for the history the owner has siad its not all there although all the servicing was done by Audi up until 2017 (i know that doesnt bode well with some people as some indies are far better than the dealer on these cars). I will go in with my eyes wide open and buy on condition, if i do buy.Your best resource is www.rs246.com.

I have not driven one, this is the first one im going to see, maybe the one you drove was in need of a carbon clean. All the report i have read and videos ive watched have all said, even for a heavy car (1650kg, not really that heavy) the V8 putting out 415hp is more than enough. I suppose it all depends on what youre used to and what youre expectaions are of the car, i will go in with an open mind and hope for the best.I went to look at one on Saturday and put a deposit down on it, should be delivered to me on Tuesday, looking forward to it and lots of plans for it too. The test drive was good and crawling all over it too was fine. Was impressed with the engine even though I couldnt see a receipt for Carbon clean so i might just get that done soon as a base to start again from.
