Default S8 - Amazing Experience + Questions for Forum Members

Hi everyone,

I am the proud new owner of a 2007 S8. This is my first Audi -- the S8 is like a drug. All I can say is WOW.

I bought her with 49,850 miles on the odometer in Night Blue Pearl Effect. She was a lease return that was picked up at an auction by a Lexus Dealership in California. It appears (at least on the surface) that the car was pampered.

From the maintenance records I've read, the car appears to have been aggressively serviced at Santa Monica Audi. The owner did all maintenance on-time and some big wear/tear items were addressed in the last 5k miles - all brake pads and rotors were replaced @ 45k miles last year, all tires were replaced. A few other minor repairs were also in the list (trim issue, window replacement, etc).

A few days after I purchased the car, I took her to my independent Audi mechanic to get her in tip-top shape. (P.s. Found the mechanic through the AudiWorld forums -- hope he turns out to be honest, capable and reasonable)

I asked to have a detailed inspection ASAP. The issues I asked the mechanic to focus on were the ones I found after I took possession:

(1) After driving the car 60 miles, a false positive oil level warning light ("check oil min level" - yellow light) turned on. Oil level looks good from dipstick reading and oil/filter was last changed by Lexus dealership in May. (After I check the dipstick and close the hood, the warning light goes off and then turns back on in 60 miles.) mechanic tells me it is a bad sensor and he can change it out after he drains the oil.

(2) The other issue is a that the Navigation seems to be flaking out intermittently with a check DVD message. (The DVD looks like a burned copy, which might be the problem. I am also told that the DVD units fail frequently on the S8). No Aux-In or iPod connector -- no big deal, but was surprised that this as an option and not standard for a 2007.

(3) I heard a rubbing/low whine coming from the passenger side wheel well when I turn right. I only heard this noise two times in a few days of driving and for only about 2 seconds. It only seems to happen when I'm turning into my driveway, so it may just be the way the ingress/egress are affecting the suspension. Unable to reproduce noise with the mechanic during test drive, and visual inspection on the rack does not show any issues or rubbing. M
My mechanic tells me that it looks like the upper control arms were replaced in early 2013.

I asked my mechanic about preventive maintenance on the carbon-buildup issues that plagues the FSI engines. He advised that this issue is nature of the beast with FSI engines, and told me he has successfully used solvents as a preventive measure. Not sure what to believe on this issue.

In any case, I approved a 55k mile/6 year service with the carbon-buildup solvent treatment and a comprehensive inspection. A full report on the way.

QUESTIONS FOR BOARD MEMBERS

I've been lurking for a while, as I have always been fascinated by this car, and appreciate all of the expertise from the board-members. I do have a few questions for members, where my forum searching skills have failed me.

1. How many D3 S8's were produced? I read somewhere that only ~250 were imported into the United States every year. Is that true?

2. I do not have a warranty on this car. I've budgeted $15k-$20k for maintenance/repairs over the next 3 years, and intend to drive her as a weekend car w/ intention to put ~7,500 a year in mileage.Does this seem like reasonable maintenance budget assuming that car has been well cared for? --- My mechanic stated that catastrophic failures on the 5.2L V10 on the lambo (thrown rods) were known to happen -- while noting the difference between the 5.2L in the Lambo and the 5.2L in the S8. He thought catastrophic engine failures might also be a random issue with the D3 S8. But when I pressed him on this point, he admittted that he doesn't know a lot about S8 statistics (with so few of them around) and couldn't definitively advise re: the odds of a major tranny or engine failure on the car?

Is catastrophic failure of the engine/drive-train a meaningful risk with the S8? My other weekend car is an 2000 Acura NSX. The V6 there is bullet-proof -- I'm told that Acura has never had to replace a engine 3.0L or 3.2L NSX engine under warranty. Any opinions on S8 reliability and risk of catastrophic engine or tranny failure would be appreciated?

3. In light of #2 above -- does it make sense to purchase an after-market warranty? Lots of conflicting opinions on this board and others. Has anyone successfully used an after-market warranty to cover S8 tranny or engine issues? Am I better off banking the money and paying the piper if issues manifest themselves? I'm not mechanically inclined so the idea of buying a Bentley manual and becoming handy on the car beyond simple tasks is probably overzealous. ("We each play with the gifts God gives us")

Thanks in advance and cheers.

Sounds like a terrific car, hope your mechanic fixes the issues and finds the car in solid shape.

I may be in the minority on this forum, but I believe in buying a used car at a good price and spending on the best aftermarket warranty I can find. Especially on cars of this caliber when routine ware and tear gets rather pricey. I have a Fidelity extended warranty on my A8L and it has paid for itself already and I still have 16 months and 15K miles to go. I have owned warranties on BMW, Mercedes and a Cadillac and they have all done me well, absorbing well above 3 to 4 times the cost of the warranty in each case.

Personally, I wouldn't own an expensive to fix German flagship without an extended warranty.

Other's will disagree, but the facts in my case demonstrate they have been solid investments. And, I like it when I can take it to a dealer for an issue. Once out of warranty its another story. I will do as much myself as I am confident in doing so. The rest will be via a trusted independent and dealer on an as needed basis.

No warranty that i know of will cover certain "sure to fail" items given time; like the air suspension struts our cars; but yes on the compressor. Timing belt is considered maintenance and not an issue on the post 2006 models so you're good there. So the likely things to fail will be covered, suspension bushings, water pumps, a/c compressors, electronics, trunk motor, sun roof wind deflector motor, alternator, etc. will be covered. If you have the means and by your own note of budgeting $15-$20K over 3 years, it sounds like you do. I would seek the most comprehensive coverage with the lowest deductible you can find. Estimate it will cost ~$4K (maybe less).

Then drive the hell out of that amazing car....

Just my opinion!

Thank you for the prompt and helpful insight. I'm really excited and grateful to have an S8 -- part of me wants to just start using the car as a daily driver because it is an absolute joy on the road. (I drive a 2008 Cadillac STS V8 as my daily -- it's comfortable but very bland)

Glad to hear that your warranty has paid for itself many times over. I will take your experience into consideration. With the S8 I purchased being out of warranty, I don't think I will be able to find/qualify for a solid exclusionary warranty plan (which is what I suspect you have).

I know the prices for these warranties can range widely, do you mind if I ask you how much you spent on yours and how/when you purchased it?

Looking forward to hearing the experience of others.

Thanks. I assume you are referring to D3 S8 -- Between 2006 - 2010...that is an average of 325 a year. Pretty low #'s.

Save your money for a manifold off mechanical action carbon cleaning, solvents by themselves do very little if any.

USA S8 (1749);
2007 - 1144 imported
2008 - 396 imported
2009 - 209 imported

Correct, I have always purchased a minimal exclusionary plan while the used car was still under factory warranty. The price difference is significantly lower when purchased this way. IIRC, paid around $3,500 to $3,800 in 2010; with zero deductible. Shop around as dealers compete on price to sell an extended warranty. Ironically, I purchased my Fidelity warranty through my local Toyota dealer as the finance manager there simply saw it as a way to mark up a service without carrying any inventory.

Not familiar with catastrophic engine failures on these cars. The V10 is derived from the 4.2 V8 and more served as the basis of the later Gallardo and R8 V10's (with the 5.2l) as opposed to being derived from the early Gallardo engine (5.0l), as I understand.

What is a realistic figure to budget for this? Figure I will do it at some point.

Your worrying to much. Get the car up to snuff maintenance wise and just do the prevent maint. Any issues that come along the way just fix/handle them. You'll spend hours upon days thinking/planning. Sometimes you can run into a big issue (more prone to W12's), the S8 is a solid car don't worry as much, and no I'd pass on the warranty. Search through the threads as their are SOOOOOO many that cover warranties. It's a to each their own kind of topic. Me personally, use the money to fix the car whenever anything happens, and just do the maintenance on the car on time and watch it.

I have read anywhere up to $2K, it would be good to post this question in the Carbon Buildup thread as well.

I was quoted ~$1200 - $1400 (10 hours or work) by an independent Audi mechanic in the Bay Area.

Do yourself a favor and buy the extended warranty. The experienced, knowledgeable people on the forums will tell you that owning a car like ours, weather it's a daily driver, like mine or a weekend driver, like you are planning, will cost money to keep it running as it should.

I have been back to the dealer 4 times this year alone, (both front airbags on the suspension, TPMS replacement, leak on the water pump and replacement of the thermostat, trunk motor and struts). Just in these repairs, the approximate retail would have been around $6k. My warranty cost $4500 with no deductible.

The warranty has also replaced the manifold and all fuel injectors, as well as bushings, 1 rear B&O speaker, door handle and passengers arm rest.

My Beast has been serviced exclusively at Downtown LA Audi since new, (bought it 2 years ago with 44k, lease return). I now have 71k and love every minute I am in it.

BTW, my mechanic there tells me I have to drive it HARD every once in a while, to lessen the carbon build up that is prone to the 2007-10 S8's.

Besides the having to take it downtown (pain), it's become an adventure to see what loaner I am going to get. Two weeks ago I drove a 2014 S4 for a week. Fun, cute...no S8.

Hope this helps.

Default Broad warranty coverage [probably not even practical]/core engine reliability

Going back to your original question on the motor, having been here since the S8 was first intro'ed, I'm not sure I remember even one post on a catastrophic S8 motor failure, and perhaps not even one on oil burning or some such that led to a motor replace.

More generally, the core drivetrain on D3's is solid no matter what the motor. Very few reports in general on motor or tranny failures, now even with many higher mileage ones way off warranty. Much different than the D2, where the prior 5 speed tranny became well known as a weak spot. Maybe an occasional radiator issue, but not all that common either. Thus in terms of warranty, I would tend toward either extensive coverage (at the right price), or going bare and factoring the $ into your annual budget. Things likely to come up over time but where you have to be careful on exclusions/fine print are the front upper control arms, various sensor issues, some HVAC door/flap and general effectiveness (often just refrigerant) issues, MMI screen motor issues, various door switches, trunk motor and latch, TPMS sensors, soft close doors and the like. Thus even on a broad coverage basis, some of those will still be defined out. On a narrower coverage basis, likely most all.

When my CPO ran out, I was a bit too high on miles to get the broadest coverage ("Platinum") type plans. I tested the other plans (like "Gold") against the known D3 issues like some of the above and others I had experienced or knew about. Many if not most weren't even covered, or the "wear and tear" caveat would knock them out too--which I asked my service advisor about in very specific terms like upper control arms and lower sway bar links. Having since run two+ more years and 25K miles, I have mostly dealt with the things mentioned here that would not be covered except by very broad coverage plans--that I couldn't even get if I was willing to pay the premium.

Your mechanic is giving you bad advice, and there were no 2010 S8s imported into the US.
Under low load and high revs the Fine Oil Separator will start to bypass and let vaporized oil from the crankcase into the intake manifold, this has the effect of contributing even more to the problem.
Even taking that out of the equation, heating the intake valves with hard driving may help in some small manner over an extended period of time, but it would do nothing for the buildup in the intake runner area leading to the valves.

Thank you for sharing your thoughts. Your counsel is insightful. Your comments are consistent with my own due diligence -- that the D3 S8 drive-train is solid -- the weak point tends to be suspension and electrical issues. (which can cost $$$ but are not catastrophic).

I'm a huge fan of Ayrton Senna. That is one of the reasons I bought an NSX!

You are a lucky man to have attended the 1984 Monaco Grand Prix! I was not there... but then again, I was only 4 years old at that time... so even I was there, I probably would not have remembered much.

I found an aftermarket exclusionary warranty from Nissan Motor Co. (QualityGuard+) The coverage appears fairly broad. Below are the excluded items. Would appreciate feedback to the excluded items --- they appear to be wear/tear, so in my mind this is very broad coverage. The warranty terms are either 3 years/36k miles for $4300 or 4 years/48k miles for $4900.
