B7 Audi RS4 Upkeep & Patrons Information – Nick’s Automotive Weblog


The B7 (2007-2008) Audi RS4 is particular for a lot of causes; firstly, it was the one two years that Audi ever introduced the RS4 to America. It’s additionally the one widebody Audi sedan offered with a handbook transmission and a V8…and regardless that the market is beginning to warmth up, it’s nonetheless among the best bargains for Audi fanatics who need a ridiculously enjoyable automobile for below $30K.

Whether or not deserved or not, the automobile has status for being excessive upkeep…after nearly a yr of possession, plus tons of analysis on boards, homeowners teams, and talking with fellow homeowners – I’m right here to shed some gentle on this matter from the expertise of tons of of fanatics.

For many who don’t need to skip forward – my agency perception is that this automobile is extremely dependable for an fanatic car. The catch, after all, is to maintain up with the preventative upkeep. Should you’re pondering of shopping for one, understanding what has been accomplished lately (or not) will assist you to perceive should you’ve obtained plenty of payments developing or not…however to those that handle the automobile, you possibly can anticipate the engine to final nicely over 200K miles of enjoyable.

My RS4 has produced 144,444 miles of smiles.

B7 RS4 Possession Myths Debunked:

The status of the automobile being “excessive upkeep” on the boards are largely a mix of ignorance/confusion, plus the sting of recent RS4 homeowners who purchased a poorly maintained automobile and needed to foot a giant invoice of things as soon as they obtained the automobile – satirically as soon as these preliminary gadgets are mounted, the vast majority of homeowners can have troublefree possession for a few years to return…nevertheless it’s a human bias to recollect the sting of the fee, and conveniently neglect the entire occasions that nothing occurred.

Nonetheless, listed here are some chilly laborious info to know:

Timing chains/guides will not be an issue on the RS4 – the largest fable is folks worrying concerning the timing chains (and particularly the plastic guides) on this automobile…that challenge is just particular to the B7 S4 engine, and NOT the RS4. Whereas each the S4 and RS4 have V8s of the identical measurement (4.2L), these are fully completely different engines. The RS4 has the BNS motor which is greater revving (8,250 RPM redline) and produces extra energy, in addition to has direct injection. You do not want to fret concerning the timing chain service right here, so I’d argue the RS4 is definitely much less dangerous/decrease upkeep than the S4.

Upkeep prices are cheap for what you’re shopping for – particular person service gadgets are all pretty fairly priced…there are few upkeep gadgets the place an engine out service is required, and the price of elements is all fairly cheap since they’re largely shared from different Audi fashions…so elements are available and fairly reasonably priced. The problem is should you purchase a used one with years of upkeep deferred – you’re principally paying one lump sum upfront to make up for years of neglect, so after all that shall be costlier.

The motor can final a really very long time – I do know many RS4 homeowners who’ve day by day pushed their automobiles over 200,000 miles, and this example isn’t unusual. This automobile is ceaselessly day by day pushed, and never that it’s been out for 11+ years there are lots of examples nonetheless on the street which are nicely north of 100K miles with none main points.

Carbon cleansing has gotten cheaper – Count on to pay about $1,200 (plus or minus about $200 relying on the place you reside) for a great carbon cleansing. Ideally you need to do that each 20-30K miles, though I do know of some homeowners who do it quite a bit much less ceaselessly. Even should you’re day by day driving the car, that’s about $1,200 each 2-3 years of driving…concerning the set of a value of tires (and concerning the lifespan of a set of tires, too!).

So with these widespread myths debunked – what do you should find out about RS4 possession?

Essential Preventative Upkeep for the RS4

Dynamic Trip Management (DRC) – the automobile got here with an early model of magnetic experience. Whereas the automobile has a pleasant experience when working correctly, these programs are liable to failure over time and mileage…should you purchase one that’s nonetheless on the unique DRC suspension, chances are high that the struts are already leaking, or will once more quickly. Sustaining this method is dear and tough, so most homeowners inevitably substitute the system with a pleasant set of coilovers. Count on to pay wherever from $1K put in for a extra finances oriented setup (H&R Springs, Bilstien struts, alignment + set up) to over $4K for KW V3s…however the good half is that you just gained’t want to fret about this once more for a really very long time.

Carbon Cleansing – as famous earlier, you need to carbon clear the automobile each 20-30K miles. You might undoubtedly do that extra typically should you wished, as carbon begins build up instantly, however the decline in horsepower is gradual so you will get away with deferring it considerably. Should you go too lengthy, you might get some misfires and the engine gained’t be operating optimally, so should you don’t have any information of this ever being accomplished in your automobile, do it now.

Consumption Manifold Flap Failure – on a small however not insignificant variety of automobiles, the flaps on the consumption manifold will fail in certainly one of two methods…both the arms will get caught supplying you with an error code, or after a couple of carbon cleans one of many screws on the flap system will come unfastened, fall into your heads, and destroy the engine. As such, most RS4 homeowners elect to “de-flap” the car, which implies eradicating the flaps fully and changing with $30 plugs you should buy from JHM. You are able to do this throughout a carbon clear so there’s the extra labor is minimal (perhaps 1 hour, tops, to take away the flaps and set up the plugs). The one draw back is a barely rougher chilly begin, and in chilly climates it might take the engine longer to heat up. Should you’re in a northern local weather then you could possibly contemplate changing the arms with billet ones from 034, and utilizing loctite on the flap screws, however for everybody else – simply take away them in the course of the subsequent carbon clear and save your self from a probably catastrophic failure for $30…

Injector failure – one other uncommon however catastrophic occasion is that if the gasoline injectors fail/disintegrate over time, then ultimately elements get sucked into the engine. It is a failure level for any motor should you run it lengthy sufficient, so each 80K-100K miles it’s price changing the injectors. New injectors will run about $500, however whenever you’re doing a carbon clear you possibly can principally simply pop them in for little to no extra labor, and should you purchase them from FCP Euro you’ll have free replacements for all times, so it is a one-time expense of about $500…once more, a no brainer.

Oil Leaks – should you’re seeping oil from the underside of the engine, and have greater mileage, it’s in all probability the oil filter housing gasket. Change this when you’re doing a carbon clear, and also you’ll in all probability repair the difficulty. The gasket itself is reasonable, attending to it’s the tough half – however once more, whenever you’re doing a carbon clear it’s readily accessible, so a wise proprietor will do all of this on the similar time, then not have to fret about it once more for a really very long time.

Oil Cooler Traces – over time, in greater mileage vehicles, these are typically identified to fail. In principle, they need to begin with a gradual leak earlier than giving out altogether, however clearly if this goes unnoticed and also you blow a line, you’ll spray out oil in every single place…and should you don’t cease the motor instantly, you run the danger of doing harm to the motor operating it dry. You possibly can substitute this preventatively with an upgraded oil cooler line equipment for about $1,200 + labor, or you possibly can periodically examine for leaks and simply be able to shut the automobile off on the first signal of low oil stress or a low oil indicator on the sprint, after which substitute it then. This doesn’t appear to occur with all vehicles, or perhaps a majority of them, so it’s as much as you by way of your danger tolerance…I personally have opted to forgo this for now, however ought to I discover any leaking sooner or later could be one thing I’d take up.

Door blades warping – it is a small one, however the door blades are identified to retain moisture and warp. Discovering new door blades are tough as Audi not makes them, and a few of us on the RS4 Homeowners Membership on WhatsApp have begun hoarding them. Should you discover a automobile owned in a dry local weather (e.g. Southern California, Arizona, and many others.) then that is much less more likely to ever be a problem…however examine these prior to buy.

Brakes – the automobile options 8 piston Brembo brakes shared with the Lamborghini Gallardo – so don’t anticipate pads & rotors to value the identical as an A4. New entrance rotors will value about $600-800 from Brembo, pads are a couple of hundred bucks, and a full brake job will set you again $1,500 for entrance & rear (perhaps extra)…that being stated, it’s a superb setup, and never almost as dangerous as another excessive efficiency vehicles, so that is merely the value of entry IMO.

RS4 Values & What to Search for When Shopping for

So that you perceive the upkeep prices and failure factors, and you continue to need to purchase? Good for you – it’s a tremendous car, and an incredible worth, so I don’t blame you…in reality, I’ve accomplished the identical myself, and have a couple of buddies which have owned a number of RS4s as a result of they beloved it a lot they got here again to it after promoting and regretting it.

The market is getting sizzling over the past yr as individuals are catching on to what a efficiency cut price the automobile is, and likewise with V8 Guide sedans turning into rarer by the day as no producers are making new ones, and the provision of older ones dwindling as they inevitably get wrecked.

If you wish to be a wise purchaser, listed here are my tips about what to search for:

Service historical past – no matter miles, if you could find one with receipts and a documented service historical past to point out the proprietor has stored up with oil modifications and upkeep, it’s price a premium. For each merchandise above that they’ve accomplished preventatively, know that it’ll prevent 1000’s of {dollars} in upkeep, and that’s price each penny. Bonus factors for doing injectors and de-flap, as these are the one two preventative gadgets that ought to be accomplished ASAP and can prevent $3K or so of labor (assuming a carbon clear was accomplished in tandem, which 99% of the time it will likely be).

Uncommon colour or spec – whereas this was a reasonably restricted manufacturing automobile so all colours and specs are uncommon, the commonest colours are Black and Silver. Dash Blue is by far probably the most fascinating colour and often fetches a premium of $3-5K extra, and Imola Yellow and Sensible Crimson even have a powerful following. Should you discover one in an Audi Unique Coloration it may command even greater costs. In hindsight I want I had purchased a Dash Blue one each for resale worth functions and since I personally adore the colour.

Clear(ish) CarFax – Most RS4s by this level have at the very least a small blemish on their file – it’s an 11 yr previous efficiency automobile, and even when the motive force does every little thing proper you possibly can’t assist it if somebody rear-ends you or swipes you in a parking zone. A automobile with no accidents, or solely minor incidents (e.g. airbag didn’t deploy) are price a premium.

Garaged or Southern Local weather (ideally each) – Automobiles that had been nicely maintained from a detailing perspective are price a premium as they gained’t want repainted, are much less more likely to have warped sideblades, and reconditioning on the inside shall be minimal. Sticky buttons are fairly widespread and straightforward to exchange, however having unique paint in good situation is turning into rarer.

In my view, it’s price paying extra for a great instance…should you purchase the most affordable available on the market, you’re in all probability getting what you paid for. On the flip facet, I wouldn’t shrink back from greater mileage vehicles in the event that they had been maintained correctly. The engine is thought to final a really very long time, so if the earlier proprietor stored up with oil modifications & carbon cleans, and didn’t beat on it or neglect it, then you should buy fairly confidently figuring out it has loads of life left. I drive my 144K mile RS4 with none considerations or concern figuring out that the upkeep is on level and that so far as fanatic automobiles go it’s in all probability one of many extra dependable engines (particularly in comparison with any V8 BMW of the period or newer, and even the S4 of the identical era!).

In Conclusion; An Ode to the RS4

To conclude – should you’re pondering of shopping for a RS4, my suggestion is a agency sure…simply be choosy on which one you purchase, handle the preventative upkeep (or be certain another person has), and be prepared for among the best driving experiences from a sedan within the fashionable period. The excessive revving V8 is among the finest sounding V8s interval, the inside is timeless and fashionable, you possibly can row your personal gears, and the manufacturing facility wide-body traces mixed with the long-lasting wheels & Lamborghini brakes make the automobile immediately recognizable and admired by fanatics of all walks of life. I am going to an area vehicles and occasional nearly each weekend and am all the time stunned at how many individuals acknowledge the automobile and can give it compliments – far more so than vehicles price six figures that present up. As a result of Audi by no means imported the RS4 once more (a choice that also baffles me), and solely led to 2,600 of those vehicles to the US throughout a 2 yr manufacturing run (a lot of which have been totaled), it’s a uncommon automobile that may solely proceed to understand in worth over time.

Because the saying goes, they only don’t make them just like the used to…
